FIELD: chemistry.
SUBSTANCE: invention relates to a method of preparing fuel gas, which involves compression using a liquid-ring compressor, separating the compression product to obtain a gas and a liquid, membrane separation of the separation gas into a stripped gas and a recycled low-pressure unstripped gas, wherein before compression, raw gas is subjected to heating, catalytic dehydrocyclodimerisation and cooling; the working fluid used is prepared oil, and membrane separation of the separation gas further includes separation of a hydrogen-rich gas, which is then mixed with air and subjected to catalytic oxidation to obtain an oxidation gas, which is used as a heat carrier for maintaining temperature of catalytic dehydrocyclodimerisation.
EFFECT: high methane index and reduction of lower calorific power of the prepared gas for use on gas piston power plants.
