WebSep 23, 2024 · In batch reactors, the degree of conversion of reactants to products depends on the amount of time the reaction is allowed to proceed. In CSTRs operating at steady-state, on the other hand, the fractional conversion depends on the residence time … WebHeterogeneous catalytic systems have been widely studied, both experimentally and theoretically. Mathematical modelling of such processes can be classified depending upon the approach taken to address three issues. The reactor system : e.g. assemblages of catalyst particles in a gradientless environment, CSTR models, differential reactor …
