Abstract

ABSTRACT Carbon dioxide rather than oxygen seemed to be an alternative oxidant for the catalytic reaction of methane to produce C 2 hydrocarbons via oxidative coupling of methane (CO 2 OCM). The proper amount of medium and strong basic sites and the reducibility of the catalyst enhanced the CH4 conversion and C 2 hydrocarbon yield, which may be due to the synergistic effect among CeO 2 , CaO and MnO in the catalyst. The C 2 hydrocarbons selectivity and yield of 75.6% and 3.9%, respectively were achieved over the 12.8CaO-6.4MnO/CeO 2 catalyst. The catalyst showed a good stability for 20 h time on stream in the CO 2 OCM process.
