Methane, the main constituent of natural gas, is deemed to be an alternative source to replace crude oil for the production of chemicals and fuel. Direct non-oxidative methane conversion (DNMC) has been recognized as a single-step technology that directly convert methane to olefins and higher hydrocarbons. High reaction temperature and low catalyst durability, due to endothermic reaction nature and coke deposition, are two main challenges. In this talk, we would like to highlight our recent innovation in membrane and catalytic wall reactors that promotes DNMC by providing stable methane conversion, hydrocarbon selectivity, coke yield and long-term durability. These effects originate from initiation of DNMC on reactor wall, and maintenance of the reaction by gas phase chemistry in reactor compartment. The results obtained under various temperatures and gas flow rates form a basis for optimizing the process towards lighter C2 or heavier aromatic products. A process simulation was done by Aspen Plus to understand the practical implications of these reactors in DNMC.
