Finally, a pressure-swing reactor would allow to automize the cycling of the reagents and to perform much more CSC cycles, creating a precursor with a thickness of /xm. 

Four basic regenerative procedures - or hybrids thereof - can be used in conjunction with adsorptive reactor operation pressure swing, temperature swing, elution, and reaction.

Optimization of the pressure levels and the duration of inert and product sweeps in pressure swing adsorptive reactors was referred to in Section 7.4.3. One can,...

Units combining reaction and separation (a) reactor with countercurrent moving bed, (b) simulated moving-bed reactor with four catalyst layers (bold lines show gas streams during a quarter of cycle), (c) pressure-swing adsorption reactor separator (on the left i given time dependency of pressure during a cycle)...

The reactor effluent usually contains a mixture of reactants and products. It is fed into a separation section where the products are separated by some means from the reactants. Because of their economic value, reactants are recycled back to upstream units toward the reactor. The products are transported directly to customers, are fed into storage tanks, or are sent to other units for further processing. The separation section uses one or more of the fundamental unit operations distillation, evaporation, filtration, crystallization, liquid-liquid extraction, adsorption, absorption, pressure-swing adsorption, etc. In this book we typically use distillation as the separation method because of its widespread use and our considerable experience with it. Everyone is a victim of his or her experience. Our backgrounds are in petroleum processing... 

Pressure swing reactors (PSR) or sorption enhanced reaction process (SERP)... 

The usual FSR or SERF reactors combine pressure swing adsorber with a periodic flow-forced fixed-bed reactor, and involve feeding reactants in a reactor having a mixture of catalysts and sorbents. The sorbents...
