Exploring conversion of biphasic catalytic reactions: Analytical solution and parameter study
Industrial Engineering and Chemistry Research, 2007, 46(11), 7073-7078
Conversion, yield, selectivity, and catalyst consumption are among the key targets of chemical reactions in general and are particularly important for industrial application of reactions since they are the measure of overall reaction efficiency. Biphasic systems are commonly applied in the chemical industry, especially in catalytic reactions. Because of the number of physically important parameters and their interdependencies, it is difficult to predict thermodynamic conversion and yield for biphasic systems. The results of this work allow the prediction of the maximum conversion as well as the yield of any catalyzed biphasic reaction. Analytical solutions for both conversion and yield as a function of substrate ratio, phase volume ratio, equilibrium constant, and partition coefficients are given. General trends and interdependencies of the parameters of interest are discussed. The theoretical considerations are compared to experimental results. Even though simplifications were applied, the predictions fit well with the experimental outcome.
