Abstract

Abstract The effect of a range of operation variables such as pressure, low temperature and H2/CO molar feed ration the catalytic performance of 80%Co/20%Ni/30wt% La2O3/1wt% Cs catalyst was investigated. It was found that the optimum operating conditions is a H2/CO=2/1 molar feed ratio at 260°C temperature and 2bar pressure. Reaction rate equations were derived on the basis of the Langmuir–Hinshelwood–Hougen–Watson (LHHW) type models for the Fischer–Tropsch reactions. The activation energy obtained was 59.69kJ/mol for optimal kinetic model.
