    Abstract: A fluidized reactor system includes a reactor containing a fluidized bed situated above a distributor plate arranged within the reactor, a fluidizing gas fed into the fluidized bed via the distributor plate to cause uniform fluidization of the fluidized bed and promote creation of solid polymeric granules, and a valve assembly penetrating a sidewall of the reactor to remove a mixture of the fluidizing gas and the solid polymeric granules from the fluidized bed. The valve assembly is coupled to the sidewall at a downward angle relative to the sidewall such that an upward-facing opening of the valve assembly extends into the fluidized bed.

    Abstract: The present invention is generally directed to a reactor for the production of low-carbon syngas from captured carbon dioxide and renewable hydrogen. The hydrogen is generated from water using an electrolyzer powered by renewable electricity or from any other method of low-carbon hydrogen production. The improved catalytic reactor is energy efficient and robust when operating at temperatures up to 1800° F. Carbon dioxide conversion efficiencies are greater than 75% with carbon monoxide selectivity of greater than 98%. The catalytic reactor is constructed of materials that are physically and chemically robust up to 1800° F. As a result, these materials are not reactive with the mixture of hydrogen and carbon dioxide or the carbon monoxide and steam products. The reactor materials do not have catalytic activity or modify the physical and chemical composition of the conversion catalyst. Electrical resistive heating elements are integrated into the catalytic bed of the reactor so that the internal temperature decreases by no more than 100° F. from the entrance at any point within the reactor. The catalytic process exhibits a reduction in performance of less than 0.5% per 1000 operational hours.

    Abstract: A mixing device used in a fluidized catalytic cracking apparatus which mixes feed and a catalyst includes a cylindrical reaction container which supplies a catalyst in a vertical direction; a plurality of feed injection nozzles arranged along an outer circumference of the reaction container; and a catalyst flow regulator which is provided in the reaction container and regulates a flow of the catalyst in the vicinity of the feed injection nozzles. The catalyst flow regulator has no feed supply function and forms a catalyst moving bed having a hollow tubular shape which is coaxial with the reaction container in the vicinity of the feed injection nozzles. The catalyst flow regulator can effectively prevent backward flow of injected fuel. Although the mixing device has a simple structure, it has a high cracking rate and maintenance of the fluidized catalytic cracking apparatus can be performed easier.
