Theoretical Investigations of Methane Conversion to Heavier Hydrocarbons in a Plasma Reactor

Abstract

In this study, mathematical modelling of oxidative coupling of methane (OCM) to C2hydrocarbons (C2H6and C2H4) over La2O3/CaO catalyst in a fixed-bed reactor operated under isothermal and non-isothermal conditions was investigated using the MATLAB program. In this process, methane and acetylene were the inputted feed and ethane, ethylene, propylene, propane, i-butane and n-butane were the output products. The amount of methane conversion obtained was 12.7% for the former feed however; if pure methane was inputted this conversion rose to 13.8%. Furthermore, the plasma process would enhance the conversion, selectivity towards desired product and process yield. A comparison between the thermal and the plasma process showed that the methane conversion and production yield in the plasma were higher than in the thermal process under the same operating conditions. Finally, the results of the catalytic OCM and methane conversion processes in the plasma phase were compared with one another.

“…As can be seen, many research works have been done experimentally 16 – 19 and it has seen a number of limitations and difficulties. Therefore, it will be highly valuable to investigate these systems using modeling and simulation methods 20 , 21 . For this reason, this research study was conducted using modeling and simulation.…”
