Effect of Temperature and Reactants Flow Rate on the Synthesis Gas Production in a Fixed Bed Reactor

The effects of reaction temperature and flow rate of reactants on the methane conversion, product selectivity, product ratio, and carbon deposition were investigated with 13wt% Ni/MgO catalyst. Reaction temperatures were changed from 600 to 850^{circ}C, and reactants flow rates were changed from 100 to 200 mL/mim. There were no significant changes in the methane conversion observed in the range of temperatures used. It is possibly stemmed from the nearly total exhaustion of oxygen introduced. The selectiveties of hydrogen and carbon monoxide did not largely depend on the reaction temperature. The selectivities of hydrogen and carbon monoxide were 96 and 90%, respectively. Carbon deposition observed was the smallest at 750^{circ}C and the largest at 850^{circ}C. It is found that the proper reaction temperature is 750^{circ}C. The best reactant flow rate was 150 ml/min.
