Abstract: A system and process for carrying out one or more chemical reactions are provided and include one or more chemical reactors having particulate solids forming a bed therein, and a gas stripping zone forming a non-mechanical seal between said reactors which includes a conduit connecting the reactors. The conduit includes an inlet for a stripping gas which is adapted to prevent process gas from passing between reactors while permitting particulate solids to pass between reactors.

Abstract: Implementations of the disclosed subject matter provide a process for the aromatization of a methane-containing gas stream including contacting the methane-containing gas stream in a reaction zone comprising an aromatization catalyst particulate and a hydrogen acceptor particulate under methane-containing gas aromatization reaction conditions to produce reaction products comprising aromatics and gaseous hydrogen. At least a portion of the gaseous hydrogen produced is bound by the hydrogen acceptor particulate in the reaction zone and removed from the reaction products in the reaction zone. Further, the hydrogen acceptor particulate may be separated from the aromatization catalyst particulate in a separation zone under separation conditions.

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.
