摘要：
The present invention is a method for operating a rapid cycling pressure swing adsorption (RCPSA) having a cycle time, T, to separate a feed gas into a non-adsorbed gas and tail gas. The method includes the steps of passing the feed gas having a purity of F % at high pressure into a first end of a bed which selectively adsorbs the tail gas and passes the product gas out a second end of the bed for a time, F. The product gas has a purity, P %, and a rate of recovery of R %. Then the bed is cocurrently depressurized for a time, t co , followed by countercurrently depressurizing the bed for a time, tCN. The bed is then purged for a time, tP, wherein desorbate (tail gas) is released at the first end of the bed at a pressure greater than 30 psig. Subsequently the bed is repressurized for a duration, tRP
