In a process for converting methane to aromatic hydrocarbons, a feed containing methane and a particulate catalytic material are supplied to a reaction zone operating under reaction conditions effective to convert at least a portion of the methane to aromatic hydrocarbons and to deposit carbonaceous material on the particulate catalytic material causing catalyst deactivation. At least a portion of the deactivated particulate catalytic material is removed from the reaction zone and is heated to a temperature of about 700 C. to about 1200 C. by direct and/or indirect contact with combustion gases produced by combustion of a supplemental fuel. The heated particulate catalytic material is then regenerated with a hydrogen-containing gas under conditions effective to convert at least a portion of the carbonaceous material thereon to methane and the regenerated catalytic particulate material is recycled back to the reaction zone.
