A method to decompose a hydrocarbon reactant into a gaseous product and a solid product includes generating a mist of a liquid material within a reactor volume, heating the reactor volume, introducing a hydrocarbon reactant into the reactor volume to produce a solid product and a gaseous product, separating the solid product from the liquid material, removing the solid product and gaseous product from the reactor volume, and recirculating the liquid material be re-introduced to the reactor volume.

An integrated process for producing C3-C4 olefins or di-olefins including: contacting a hydrocarbon feed and a catalyst feed in a fluidized dehydrogenation reactor under conditions such that a product mixture is formed and the catalyst is at least partially deactivated; transferring the product mixture and the catalyst from the reactor to a cyclonic separation system under conditions such that the product mixture is converted to form a new product mixture and is separated from the catalyst; transferring at least a portion of the catalyst to a regenerator vessel and heating it in order to combust the coke deposited thereon; subjecting the catalyst to a conditioning step to form an oxygen-containing, at least partially reactivated catalyst; and transferring the partially reactivated catalyst back to the fluidized dehydrogenation reactor.

A method for flue gas denotation includes the step of, in the presence of ammonia, enabling flue gas in a denitration reactor to pass through a plurality of catalyst beds from the bottom to the top to participate in a denitration reaction. Each catalyst bed contains a catalyst support component and a granular denitration catalyst stacked on the catalyst support component, and, in every single catalyst bed, the granular denitration catalyst moves along a same direction on the catalyst support component. Between every two adjacent catalyst beds, the granular denitration catalyst falls from the tail of a previous catalyst support component to the head of a next catalyst support component, making the granular denitration catalyst travel along the catalyst support components reciprocatively.

An olefin polymerization reactor capable of efficiently removing heat of reaction and having excellent energy saving properties is described. The olefin polymerization reactor includes a tubular powder container forming a moving bed in which powder moves downward by gravity, and including a plurality of intermediate openings provided spaced apart from each other in a vertical direction, a gas container that accommodates gas discharged from the plurality of intermediate openings, a powder feed pipe that feeds, to an upper portion of the tubular powder container, polyolefin powder and/or slurry containing polyolefin powder and olefin monomer liquid, a liquid feed pipe that feeds olefin monomer liquid to an inside of the tubular powder container, and a gas discharge pipe that discharges olefin monomer gas from the gas container to outside.
