【Abstract】 The theory and applcation of simulated moving bed adsorption separation technology is introduced in this paper. It points out that the technology mainly applied to the separation of n-paraffins and xylenes, and expatiates the development of this technology recently. The research focuses on the selection of sorbent-desorbent and the investigation in the model to determine the fundamental data of adsorption separation process. At last, the researching status of this technology in our country and the problems existed are presented.更多还原
