    摘要： A process for separating a primary gas component from a feed gas mixture comprising the primary gas component and secondary gas components in four or more adsorption beds. The process comprises subjecting each of the four or more adsorption beds to a repetitive cycle. The repetitive cycle comprises, in sequence, a feed step, a pressure decreasing equalization step, a provide purge step, a blowdown step, a purge step, a pressure increasing equalization step, and a repressurization step. During the pressure decreasing equalization step, rinse gas is co-currently introduced simultaneous with the withdrawal of pressure equalization gas. Rinse gas is formed by compressing blowdown gas and/or purge gas effluent from the adsorption bed undergoing the purge step. The process is particularly suited for separating H2 from a reformate stream.

    摘要： A pressure swing adsorption cycle designed to reduce the variations in ozone concentration, and produce a higher average ozone concentration, in a product gas stream throughout the cycle. The cycle includes a relatively long air sweep stage and provides for the overlapping of the air sweep stage in two adsorber vessels. Effluent from an adsorber vessel in a feed rinse stage is routed to another adsorber vessel that is in an air sweep stage.

    摘要： Adsorption process for recovering ozone from a feed gas mixture containing at least ozone and oxygen comprising (a) introducing the feed gas mixture into a first end of an adsorber vessel containing a zeolite adsorbent and selectively adsorbing ozone on the adsorbent; (b) withdrawing from a second end of the vessel a stream of oxygen essentially free of ozone; (c) terminating the flow of the feed gas mixture, introducing a purge gas into the second end of the vessel, and withdrawing from the first end of the vessel an outlet gas mixture containing at least purge gas and desorbed ozone; and (d) introducing an additional component into the feed gas mixture and/or the purge gas and adsorbing the additional component on the zeolite adsorbent. The additional component when adsorbed reduces the decomposition of ozone that would occur in the absence of the additional component adsorbed on the zeolite adsorbent.
