A SLURRY-BED REACTOR AND A METHOD FOR CONDUCTION SLURRY-BED REACTION USING THE SLURRY-BED REACTOR

摘要

A slurry-bed reactor is provided in the present invention, which comprises: a reactor vessel (1), a plurality of descending pipes (28), a plurality of injectors (13) and a gas distributor (27) provided in the reactor vessel, a middle external circulation apparatus and/or a top external circulation apparatus, wherein the middle external circulation apparatus draws out at least a portion of slurry materials in the reactor vessel and at least a portion of the slurry materials is recycled back to the reactor vessel, the top external circulation apparatus draws out at least a portion of gas materials in the reactor vessel and liquid materials separated from at least a portion of the gas materials is recycled back to the reactor vessel, wherein the plurality of descending pipes are provided along the inner wall of the reactor vessel (1), the injectors (13) are provided at different vertical height in a central region of the vessel (1) with injector openings of injectors (13) being directed upwardly or obliquely upwardly. The particle suspension, liquid-solid mixing,mass transfer and heat transfer are enhanced by the slurry circulation in the slurry-bed reactor. A method for conducting the slurry-bed reaction is also provided in the present invention.
