Abstract: Implementations of the disclosed subject matter provide a process for the aromatization of a methane-containing gas stream may include contacting the methane-containing gas stream in a reaction zone comprising an aromatization catalyst particulate and an inert heat carrier particulate under methane-containing gas aromatization reaction conditions to produce a product stream comprising aromatics in the reaction zone. The inert heat carrier particulate may be separated from the aromatization catalyst particulate in a separation zone under separation conditions. The aromatization catalyst particulate may have a first minimum fluidization velocity and the inert heat carrier particulate may have a second minimum fluidization velocity which may be greater than the first minimum fluidization velocity. The ratio of the second minimum fluidization velocity to the first minimum fluidization velocity may be less than 200 and may be more than 15.
