A method and apparatus for producing a methane-containing erdgassubstituts and associated power supply system.

摘要

The present invention relates to a method and a device for generating a methane-containing erdgassubstituts from a kohlenoxidhaltigen feed gas and to a power supply system which is equipped with such a device.According to the invention, the feed gas is subjected to a methanisation reaction, for which a hyperstoichiometric proportion of hydrogen, is adjusted in the educt gas. The product gas of the methanisation reaction, by means of a gas separation into a methane-containing, the supplying for natural gas retentate divided and comprises an hydrogenous permeate gas flowing. At least a portion of the permeate, in order to feed gas is returned, and this with the formation of the educt gas for the methanisation reaction is mixed with.Use of, for example, for regenerative power supply systems with biomass recovery.
