Abstract: In a method for operating an adsorption device a laden gas stream is fed to an inlet of a sorption buffer device. In the device the laden gas stream passes through a sorbent for receiving a loading of sorbable substance along a sorption path from the inlet to an outlet. The sorbable substance passes from the gas stream to the sorbent, or vice versa, depending on the loading of the gas stream and the sorbent. During a phase of elevated loading, a region with an elevated loading of the sorbent extends from the inlet along the sorption path. During a phase of reduced loading, the region with the elevated loading of the sorbent is shifted in the direction toward the outlet. Length of the sorption path and quantity of the sorbent in the sorption buffer device are selected for accommodating at least three different regions of elevated loading.

Abstract: The invention relates to a method for generating an alkene, in which a hydrocarbon-comprising feed material is subjected to a dehydrogenation and a product material comprising at least one alkene is generated. A gas stream coming from an adsorber is cooled by a gas stream which comprises the feed material, and the gas stream coming from the adsorber is cooled by a condensed component of the gas stream coming from the adsorber in a first cooling phase. Feed material is cooled in a second cooling phase by a condensed component of the gas stream coming from the adsorber. The flow of the condensed component of the gas stream coming from the adsorber, fed to the first and/or second cooling phase, is varied depending on the temperature of the gas stream leaving the first cooling phase which comprises the feed material and which is fed to the dehydrogenation.

Abstract: The invention relates to a method for production of a methanol-synthesis gas product stream (2), an H2 product stream (3) and a CO product stream (4) from an H2- and CO-containing synthesis gas stream (5).
