CONVERSION AND SELECTIVITY o Conversion is that fraction of component entering a reactor that is converted to products and byproducts o Conversion is generally based on one or more independent key components of primary interest in the reaction system o The selectivity of a key component with respect to a specified product is the fraction of that component converted to the specified product divided by the total conversion of the key component. /2099 Chemical reactor Characterization 59/20/99 Chemical Reactor Characterization 5 CONVERSION AND SELECTIVITY u Conversion is that fraction of component entering a reactor that is converted to products and byproducts u Conversion is generally based on one or more independent key components of primary interest in the reaction system u The selectivity of a key component with respect to a specified product is the fraction of that component converted to the specified product divided by the total conversion of the key component
