Publication number: 20150174546Abstract: The present invention relates to a fluidized bed reactor capable of varying flow velocity, in which the flow velocity in the fluidized bed reactor varies to maintain the smooth transportation of solid particles while increasing the concentration of a gaseous reactant in relation to the solid particles. The fluidized bed reactor comprises: a lower high-speed unit into which solid particles and fluid particles are introduced; a middle low-speed unit continuously connected to an upper portion of the lower high-speed unit so that the flow velocity therein becomes lower than that in the lower high-speed unit; and an upper high-speed unit continuously connected to an upper portion of the middle low-speed unit so that the flow velocity therein becomes higher than that in the middle low-speed unit.Type: ApplicationFiled: May 21, 2013Publication date: June 25, 2015Applicant: KOREA INSTITUTE OF ENERGY RESEARCHInventors: Chang-Keun Yi, Ho-Jung Ryu, Young-Cheol Park, Sung-Ho Jo, Gyoung Tae Jin, Dowon Shun, Dal-Hee Bae, Jaehyeon Park, Seung-Yong Lee, Jong-Ho Moon, Dong-Ho Lee
