The oxidative coupling of methane (OCM) has attracted much attention in the target of scientific and commercial interest for recent decades due to the huge potential of the technology to reduce cost, energy, and environmental emissions in the production of ethylene. In general, hot-spot is significantly occurred with high exothermic reaction such as OCM leading to a concomitant increase of byproduct formation, and must be avoided by a proper design and selection of operation parameters. In the present study, the efficient reactor type and scale-up methodology using multi-channel fixed-bed reactor to minimize a hot-spot formation has been investigated by applying a properly selected OCM catalyst. The reactor allows a coupling of the exothermic (OCM) and endothermic (methane reforming) reaction by virtue of their thermal matching. An experimental study confirmed that the heat absorbed in the reforming reaction indeed partly come from that evolved in the OCM reaction, and the temperature of OCM catalyst bed were steadily controlled during OCM reaction. |
