Abstract: A process includes flowing a catalyst composition comprising catalyst particles into a radial flow moving bed reactor, wherein the catalyst particles move by gravity through the radial flow moving bed reactor to an exit point of the radial flow moving bed reactor, wherein the catalyst particles form a moving catalyst bed in the radial flow moving bed reactor, flowing a light hydrocarbon feed stream comprising C1 to C3 alkanes into the radial flow moving bed reactor in a manner so that the light hydrocarbon feed stream flows radially inward or radially outward through the moving catalyst bed and thereby contacts the catalyst particles under reaction conditions to produce a product effluent stream comprising a C2 to C10 hydrocarbon product and hydrogen, and flowing the product effluent stream from the radial flow moving bed reactor.

Abstract: Methods for regenerating spent catalysts, including spent catalysts used in in the catalytic conversion of a hydrocarbon feedstock. The method and associated processes comprising the method are useful to recover spent catalysts used in the petroleum and chemical processing industries. The method generally involves the use of an aqueous leaching solution to leach catalytically active metals from the spent catalyst so that solid carbon built up on the catalyst may be separated from the catalyst metals. The recovered catalyst metals, or a catalyst formed therefrom, may then be re-used in a catalytic conversion process.

Abstract: A reactor uses catalyst blocks for conversion of light hydrocarbons to hydrogen and to liquid hydrocarbons. The catalyst blocks stacked on top of one another within the reactor facilitate conversion of the light hydrocarbons. Electric heaters can be arranged in a variety of orientations within the reactor to supply heat for the conversion reaction. Alternatively, the catalyst blocks can be located within reaction tubes within the reactor and heated by combustion of a fuel adjacent to the reaction tubes. When operated in a regeneration mode, coke that accumulates within the reactor is removed by oxidation.
