Abstract: An apparatus for performing continuous flow chemical reactions such as oxidation, oxidative dehydrogenation and partial oxidation processes involving a reactor design characterized by controlled/optimized addition of a reactant with the objective of: (i) avoiding the explosion regime of the reactant mixture (e.g., hydrocarbon/oxidant mixture); (ii) maximizing the selectivity of the reaction to the desired product; (iii) limiting the reactor temperature gradient and therefore the threat of reaction runaway; and (iv) controlling the operating temperature of the reaction zone so that desirable temperature range is maintained over the entire zone.

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: 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.

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.
