Abstract: This invention relates to a novel fluidized bed membrane reactor for autothermal operations. More particularly, this invention pertains to a unique fluidized bed membrane reactor which includes internal catalyst solids circulation for conveying heat between a reforming zone and an oxidation zone. A method of producing hydrogen gas from a hydrocarbon gas and steam comprising forming a fluidized bed of a suitable particulate catalyst in a reactor, wherein the catalyst is disposed in the reactor in two reaction modes, the first being an endothermic dehydrogenation reaction mode and the second being an exothermic oxidation or partial oxidation reaction mode, introducing a mixture of steam and hydrocarbon gas into the bottom of the fluidized bed to fluidize the particulate catalyst and form the fluidized bed, reacting the steam and hydrocarbon gas within the first endothermic dehydrogenation reaction mode to produce hydrogen gas, separating said hydrogen gas from other gases in the first endothermic dehydrogenation reaction mode as molecular or atomic hydrogen through a perm-selective membrane that permits the transfer of hydrogen therethrough while preventing or minimizing the transmission therethrough of the other gases in the endothermic dehydrogenation reaction mode, introducing oxidant in the second exothermic oxidation or partial oxidation reaction mode, and mixing same with other gases in the second exothermic oxidation and partial oxidation mode, and directing resultant oxidized gases to the first endothermic dehydrogenation reaction mode.

Abstract: A reactor configuration for fluidized bed reactors in which large exposed fixed surface area per unit reactor volume is required. The configuration uses a serpentine or hairpin bend arrangement of continuously connected and communicating thin channels, with the containing surfaces of these channels being vertical. This configuration enables uniform fluidization of particles throughout the cross-sectional area of the reactor and facilitates dispersal of membrane surfaces, heat transfer surface and baffles in gas-solid fluidized bed reactors.

Abstract: Hydrogen gas is generated in a fluidized bed reactor by reacting gases namely steam and a hydrocarbon gas such as methane or natural gas in a fluidized bed of particulate catalytic material. The catalytic material is fluidized by injecting the mixture of the reacting gases at the bottom of the bed. Hydrogen generated within the bed is removed via a selectively permeable membrane that extends through the bed and through a freeboard area above the bed. The reaction is endothermic and therefore heat to maintain the bed at the desired temperature is added as required. Preferably a separator separates particulate catalytic material entrained in the gases in the freeboard area and delivers the particulate material separated from the gas back into the bed.
