    Abstract: A fluidized bed reactor system including a fluidized bed reactor configured to receive a heated light hydrocarbon feed stream flowing upwards and a heated regenerated catalyst at a temperature sufficient to crack the heated light hydrocarbon feed stream to produce a product effluent stream containing hydrogen and spent catalyst having coke deposits, a catalyst regeneration unit operatively connected to a bottom portion of the fluidized bed reactor, the catalyst regeneration unit being configured to receive the spent catalyst flowing downwards and combust the coke deposits to produce the heated regenerated catalyst and a heated gas effluent for generating the heated light hydrocarbon feed stream, and a riser externally attached to the fluidized bed reactor and the catalyst regeneration unit, the riser being configured to receive the heated regenerated catalyst and a gas-based stream to flow the heated regenerated catalyst upwards to the fluidized bed reactor.

    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.

    IPC: C10G11/16

    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.
