Development of a recycle reactor system and modelling of a fixed bed catalytic reactor

Abstract

An ex erimental set up was.developed to study the kinetics .of heterogene us catalytic reactions in a recycle reactor system. Literature r iew was made on the kinetics, mechanism, multiplicity, and oscillatory behaviour of carbon monoxide oxidation and an experimental program was suggested. In part II of the thesis, a model was developed for simulating shift converters. The conversion of carbon monoxide with steam can be achieved in a number of different ways. Various possible strategies were discussed and the most widely accepted and economic system was simulated for various operating conditions to find the minimum amount of catalyst required. Different combinations of inlet temperatures and outlet carbon monoxide concentrations to both the high temperature and low temperature shift converters are tried in.anattempt to develup optimum operating conditions. The models are used to simulate twO operating plants in the country and the results indicate consistency of plant conditions to that of the simulated results wlthin acceptable range.
