Abstract: A process is proposed for producing one or more electrolysis products using an electrolysis arrangement, which comprises the withdrawing of anode gas and water from the electrolysis arrangement in a biphasic mixture, the feeding of the biphasic mixture or a portion thereof into a separator arrangement, the treating of separator gas from the separator arrangement in a catalysis arrangement, and the feedback of catalysis gas from the catalysis arrangement into the separator arrangement, wherein the anode gas and the separator gas contain oxygen and a smaller proportion of hydrogen, and wherein the catalysis gas is depleted of hydrogen by the treatment in the catalyst arrangement. The present invention likewise provides a corresponding apparatus.

Abstract: A polymerisation system for obtaining at least one polymerisation product from at least one gaseous, hydrocarbon-rich feed stream, which system has at least one catalytic and/or adsorptive cleaning device for the at least partial extraction of at least one undesirable component in the at least one feed stream and a regeneration device for the regeneration of the cleaning device. The regeneration device is designed to at least intermittently condition and conduct a regeneration gas stream through the cleaning device by means of a partially closed gas circuit. There is further provided a corresponding regeneration method.
