Oxidative coupling of methane, ethylene, synthesis gas, dual function catalyst, membrane reactor.
Abstract
The direct route for the production of ethylene from natural gas via oxidative coupling of methane (OCM) in a single step is still high on the industrial wish-list, but has proven a major scientific and technological challenge. However, when the exothermic oxidative coupling of methane is combined with endothermic steam/dry reforming of the by-products of the OCM and additional methane, ethylene and syngas can be produced simultaneously in an autothermal process. Thus, a higher methane conversion (avoiding a large methane recycle) and efficient use of the by-products of the OCM is combined with optimal heat integration.
The integration of the exothermic and endothermic reactions is optimally achieved on the catalyst particle scale, which would make the reactor configuration much simpler (no lateral temperature gradients in the reactor) and cheaper compared to a non-isothermal membrane reactor. Detailed simulations on the integration of the reactions on the particle scale have been carried out in a previous ASPECT project titled ‘Simultaneous production of ethylene and synthesis gas combining the oxidative coupling and reforming of methane in a reverse flow membrane reactor with a dual function catalyst’, and have shown that it is theoretically indeed possible to integrate the oxidative coupling and steam reforming of methane on the particle scale, making effective use of intra-particle mass transfer limitations.
The simulations have led to a first possible design of the dual-function catalyst particle. In this follow-up project, we propose to actually fabricate the dual-function catalyst and to demonstrate its performance for the combined autothermal process experimentally. The deliverables of the project are new knowledge on the fabrication of dual-function catalysts, detailed reaction kinetics for this reaction system and an experimental proof-of-principle of reaction integration on the particle scale in a packed bed membrane reactor.
