The bio diesel is a kind of renewable energy, and has the advantages of high sixteen value, non-toxic, non sulfur, renewable and biodegradable. Its application and promotion is the best way to solve the problem of energy substitution at this stage. Today, the development of foreign bio diesel industry is rapid, and the output is increasing year by year, while the Chinese bio diesel industry is just beginning. This review summarized the different methods of bio diesel production, and introduced the technology and strategy of the upstream and downstream of the production. Key words: Bio diesel; current situation; development prospect 0 Introduction In the rapid development of modern society, people's dependence on oil is increasingly strong, oil restricts the economic development of countries in the world, is the lifeblood of the country. But increasingly nervous energy, soaring oil prices, coupled with environmental pollution factors in, countries all over the world have to speed up the exploration of new and renewable sources of energy. Biomass energy and solar energy and other renewable energy become mainstream, and the bio diesel is a renewable and environmental protection, and has won the attention of all countries. 1 Development history of bio diesel Bio diesel is a renewable diesel fuel, which is made from the oil plant, the wild oil plant and the engineering micro-algae, and the oil and the animal fats and oils, etc.. Bio diesel is a kind of biomass energy, which is a kind of long chain fatty acid, which is obtained by the pyrolysis of biomass. Bio diesel is a kind of complex organic compounds with high oxygen content. These compounds are mainly organic compounds with high molecular weight, almost all kinds of organic compounds, such as: ether, esters, aldehydes, ketones, phenol, organic acids, alcohols, etc.. In 1983, the American scientist Quick Graham was first used to prepare the oil methyl ester was used in the engine, and put forward the set of bio diesel. In 1988, bio diesel was born in Germany Nell company, its invention to Rapeseed Oil as raw materials refined clean fuel

2 Main characteristics of bio diesel Bio diesel is a kind of biomass energy,which contains 77%carbon,12%hydrogen,11%oxygen and trace sulfur and nitrogen.Bio diesel as an exchange product of animal and vegetable oils,according to chemical composition analysis,is generally made of high fatty acid esters of 14--18 carbon atoms,and is very phase of petrochemical diesel oil.It is basically no sulfur and aromatic hydrocarbons,sixteen alkanes value of up to 52.9,can be biodegradable,non-toxic,harmless to the environment,can meet the requirements of the health impact of the u.s..In the process of producing bio diesel,the mineral energy per unit of each unit can be obtained by the energy of 3.2 units,and in all of the alternative energy,the unit value of the unit is the most.Compared with the use of petrochemical diesel,it opens high flash point, storage,use,transport are very safe,with many incomparable performance.

In the process of producing bio diesel, the mineral energy per unit of each unit can be obtained by the energy of 3.2 units, and in all of the alternative energy, the unit value of the unit is the most. Compared with the use of petrochemical diesel, it opens high flash point, storage, use, transport are very safe, with many incomparable performance.

As renewable energy, and oil reserves are different, and its supply of agricultural and biological scientists will not be exhausted. (7) Without changing the diesel engine, can be added directly to use. At the same time, no need to put gas equipment, storage equipment and personnel training in special skills. (8) Bio diesel to a certain proportion of the use of petrochemical and petrochemical, can reduce fuel consumption, improve power, and reduce pollution. It shows that the advantages of bio diesel is not only adapted to the current needs of the social and

economic development,but also a significant contribution to the sustainable development of human beings.The carbon dioxide emitted by the combustion is much lower than the carbon dioxide absorbed by the plant growth,and it also helps to slow down the greenhouse effect and is the real green diesel fuel. 3 development status of bio diesel With the rise of oil prices,bio diesel has got more and more attention,and many countries have introduced policies and measures to encourage the development of bio diesel.Bio diesel production from 2004's 21.96 L soared to 98.41 L in 2007,an average annual growth of 25.48.At present,countries in the world,especially in developed countries,are working on the development of high efficiency and non polluting energy use technology.Europe has become the main production of bio diesel oil.The United States,Italy,France has built a bio diesel production device dozens.Development of bio diesel,raw material is the key.There are many kinds of raw materials to produce bio diesel,and all countries have chosen to have their own advantages in the production of raw materials.The United States uses genetically modified soybean oil,the European development of rape,some Southeast Asian countries are using their rich palm oil.Among them,palm oil,jatropha oil,algae bio diesel feed-stock is slowly rising.China began the research and popularization of bio diesel more than ten years ago,but the shortage of raw materials is an important factor to restrict the development of bio diesel.Our country although is the world's largest rapeseed,cottonseed,and peanut production in,as well as the global fourth largest soybean producer,but oil production cannot meet the needs of the people's daily food.According to statistics,in 2004 China's per ca-pita oil consumption of 17.6kg,the total demand of 13 million people of edible vegetable oil T,while the domestic oil production is only 1400 t.To this end,2004 annual imports of edible oil of 676 million T,which imports of soybean oil 252 million T,35.3 million tons of rapeseed oil,239 million tons of palm oil,soybean imports 20.23 million T,rapeseed 47 million.Therefore,in order to develop the bio diesel industry in China,we must take the problem of solving the raw material of bio diesel.Only to solve the problem of raw materials,bio diesel in our country to have a stable development direction.China's bio diesel production technology is mainly to conventional acid-base and modification of acid and alkali,solid molecular sieve as catalyst of practical technology and lipase as catalyst and super critical without catalyst technology reserve system.At present,China's bio diesel oil is mainly based on the poor quality of the waste gas,the use of acid and alkali catalyst.Because of the short process route,it is seldom to be treated with glycerol,which is usually only used as fuel oil.In the process of the use of vacuum distillation technology,to ensure that different raw materials can produce the same quality of bio diesel.As a result of our country has no unified standard of bio diesel,the product quality is different,but

economic development, but also a significant contribution to the sustainable development of human beings. The carbon dioxide emitted by the combustion is much lower than the carbon dioxide absorbed by the plant growth, and it also helps to slow down the greenhouse effect and is the real green diesel fuel. 3 development status of bio diesel With the rise of oil prices, bio diesel has got more and more attention, and many countries have introduced policies and measures to encourage the development of bio diesel. Bio diesel production from 2004's 21.96 L soared to 98.41 L in 2007, an average annual growth of 25.48. At present, countries in the world, especially in developed countries, are working on the development of high efficiency and non polluting energy use technology. Europe has become the main production of bio diesel oil. The United States, Italy, France has built a bio diesel production device dozens.Development of bio diesel, raw material is the key. There are many kinds of raw materials to produce bio diesel, and all countries have chosen to have their own advantages in the production of raw materials. The United States uses genetically modified soybean oil, the European development of rape, some Southeast Asian countries are using their rich palm oil. Among them, palm oil, jatropha oil, algae bio diesel feed-stock is slowly rising.China began the research and popularization of bio diesel more than ten years ago, but the shortage of raw materials is an important factor to restrict the development of bio diesel. Our country although is the world's largest rapeseed, cottonseed, and peanut production in, as well as the global fourth largest soybean producer, but oil production cannot meet the needs of the people's daily food. According to statistics, in 2004 China's per ca-pita oil consumption of 17.6kg, the total demand of 13 million people of edible vegetable oil T, while the domestic oil production is only 1400 t. To this end, 2004 annual imports of edible oil of 676 million T, which imports of soybean oil 252 million T, 35.3 million tons of rapeseed oil, 239 million tons of palm oil, soybean imports 20.23 million T, rapeseed 47 million. Therefore, in order to develop the bio diesel industry in China, we must take the problem of solving the raw material of bio diesel. Only to solve the problem of raw materials, bio diesel in our country to have a stable development direction.China's bio diesel production technology is mainly to conventional acid-base and modification of acid and alkali, solid molecular sieve as catalyst of practical technology and lipase as catalyst and super critical without catalyst technology reserve system. At present, China's bio diesel oil is mainly based on the poor quality of the waste gas, the use of acid and alkali catalyst. Because of the short process route, it is seldom to be treated with glycerol, which is usually only used as fuel oil. In the process of the use of vacuum distillation technology, to ensure that different raw materials can produce the same quality of bio diesel. As a result of our country has no unified standard of bio diesel, the product quality is different, but

the basic can achieve the relevant quality of bio diesel.Compared with foreign countries,China has a considerable gap in the development of bio diesel,long-term wandering in the primary research stage, failed to form a bio diesel industry:the government has not yet set up a set of support for bio diesel fuel, incentives and incentives,but did not develop a unified standard and the implementation of industrial development.Therefore,after entering the WTO,China has become more and more urgent in the background of how to face the dual pressures of economic development and environmental protection. 4 development prospects of bio diesel The development of fuel ethanol,bio diesel and bio chemical products are in line with the national alternative energy strategy.The national development plan for bio diesel is:"Eleven-five"industrial demonstration,"twelve-five"industrial promotion,"Five -thirteen".Development of bio diesel,China is very rich in raw material resources.China has a vast territory,a large geographical span,different water and heat resources,energy and plant resources are rich and varied.At present,the development and utilization of bio diesel in our country is still in the initial stage,we must reduce the cost of bio diesel, make it play a bigger role in the transformation of China's energy structure.Along with the continuous deepening of reform and opening to the outside world,in the process of global economic integration,in China's accession to the WTO of the excellent situation,will further enhance the level of China's economy, the demand for energy will continue unabated,as long as the transformation on the bio diesel research results into productive forces,the formation of industrialization,its application in diesel engine,diesel generator,air conditioning equipment and rural fuel is very broad.With the development of modern society,the modern diesel engine makes the diesel engine of the vehicle model,which makes the demand for bio diesel is more urgent.The development of bio diesel industry,the establishment of biological raw material base,characteristic planting high yield oil crops,not only can increase the income of farmers,and promote the economic development of rural areas and the surrounding areas,but also on the country's economic and social development make an important contribution,kill two birds with one stone.Coupled with its renewable and clean characteristics,the environmental protection has advantages and disadvantages,more in line with the current social development needs,I believe that the future of bio diesel will integrate into society and become an indispensable important industry

the basic can achieve the relevant quality of bio diesel.Compared with foreign countries, China has a considerable gap in the development of bio diesel, long-term wandering in the primary research stage, failed to form a bio diesel industry: the government has not yet set up a set of support for bio diesel fuel, incentives and incentives, but did not develop a unified standard and the implementation of industrial development. Therefore, after entering the WTO, China has become more and more urgent in the background of how to face the dual pressures of economic development and environmental protection. 4 development prospects of bio diesel The development of fuel ethanol, bio diesel and bio chemical products are in line with the national alternative energy strategy. The national development plan for bio diesel is: "Eleven - five" industrial demonstration, "twelve - five" industrial promotion, "Five - thirteen".Development of bio diesel, China is very rich in raw material resources. China has a vast territory, a large geographical span, different water and heat resources, energy and plant resources are rich and varied. At present, the development and utilization of bio diesel in our country is still in the initial stage, we must reduce the cost of bio diesel, make it play a bigger role in the transformation of China's energy structure.Along with the continuous deepening of reform and opening to the outside world, in the process of global economic integration, in China's accession to the WTO of the excellent situation, will further enhance the level of China's economy, the demand for energy will continue unabated, as long as the transformation on the bio diesel research results into productive forces, the formation of industrialization, its application in diesel engine, diesel generator, air conditioning equipment and rural fuel is very broad. With the development of modern society, the modern diesel engine makes the diesel engine of the vehicle model, which makes the demand for bio diesel is more urgent. The development of bio diesel industry, the establishment of biological raw material base, characteristic planting high yield oil crops, not only can increase the income of farmers, and promote the economic development of rural areas and the surrounding areas, but also on the country's economic and social development make an important contribution, kill two birds with one stone. Coupled with its renewable and clean characteristics, the environmental protection has advantages and disadvantages, more in line with the current social development needs, I believe that the future of bio diesel will integrate into society and become an indispensable important industry
