Abstract
The artificial moving bed of this invention includes a fluid distribution apparatus consisting of an upper fluid distributor and a lower fluid distributor, and a plurality of processing chambers held and fixed between the upper and lower fluid distributors. Each fluid distributor has a rotary valve held in a slidable condition between a fixed supply valve and a pipe fixing plate. These fluid distributors are formed with fluid passages therein. The processing chambers are divided into several groups, each assigned a specific process. Using this artificial moving bed, the processing chambers are operated simultaneously and when the process is finished in each group of processing chambers, the fluid distribution apparatus is rotated clockwise when viewed from above so that each group of chambers proceeds to the next process, thus allowing continuous adsorption operation.
