Abstract

Nowadays converting synthesis gas to makes olefins is an important issue and researcher has been focused on it. The kinetic experiments for synthesis gas reactions over RIPI-Co/Mn catalyst to light olefin are carried out in a micro-fixed-bed reactor under the following conditions: temperature 220–300°C, pressure 1–5 atm, H2/CO feed ratio 1–3, and space velocity of 450-600 h−1. In order to obtain the parameters of the kinetic model, the optimum values of the kinetic parameters have been obtained. The global minimum for the optimized function has been achieved, with using the genetic algorithm. The data of this study were best fitted by a Langmuir-Hinshelwood (LH) rate form Rco = kPcoPH21/2/ (1+aPco+bPH21/2)2.
