Abrégé
The present invention provides a slurry-bed reactor comprising a reactor housing (1), and a lowergas inlet assembly, a reaction zone vessel (6), sedimentation tube (5) and an upper outlet (14), wherein the upper outlet (14) is used for discharging gas materials from said chamber and said lowergas inlet assembly is a Venturi equipment. The outlet of the lowergas inlet assembly is in fluid communication with the lower part of the reaction zone vessel (6)and the lower end of the sedimentation tube (5) is in fluid communication with the flank of the lowergas inlet assembly. The inside of the reactor house is configured to allow a slurry to pass through the reaction zone vessel (6), the sedimentation tube (5), the lower gas inlet assembly and the reaction zone vessel (6) sequentially to form a flow cycle. In examples described, the gas inlet assembly facilitates the mixing and mass transfer efficiency in said reactor. The present invention also provides a method for conducting slurry-bed reaction using the slurry-bed reactor.
