Abstract
A process and catalyst for use therein for the production of aromatics via the oxidative coupling of methane and methane co-aromatization with higher hydrocarbons in a single reaction stage. First, methane is partially converted to ethane and ethylene on an OCM catalyst component, and the OCM intermediate mixture containing methane, ethane and ethylene is subsequently converted into aromatics on an aromatization catalyst component. The reaction may be conducted at 550-850° C. and at about 50 psig. The claimed process and catalyst used therein achieves high methane conversion at lower temperatures (less than 800° C.), higher methane conversion into the aromatic products and significant reductions in production cost when compared to the traditional two (or more) step processes.
