Abstract

ABSTRACT: In this research, the effect of operating conditions, such as GHSV, temperature and CH4/O2 ratio was investigated on the catalytic performance of OCM in a Fixed-Bed reactor. 50 g of catalyst was loaded in a stainless steel reactor. Heat control in OCM is very important. With attention to this fact series of experiment were designed to investigate the influence of above-mentioned parameters on C2+ selectivity, CH4 conversion and the YIELD of C2+. The C2+ selectivity of 73 % was obtained at a CH4 conversion of 12.58% at 840oC, 1320 hr-1 GHSV and CH4/O2 ratio 4 to 1. The OCM reaction is strongly dependent on the operating condition particularly GHSV and the CH4/O2 ratio. The comparison of these results and micro reactor in literature, show that the scale up of fixed bed reactor in OCM reaction without too much change in YIELD and selectivity of C2+, CH4 conversion and COx selectivity, with an appropriate GHSV, CH4/O2 ratio is technically feasible and economic.
