FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing hydrocarbon compounds, which is characterised by that it includes the following: a) feeding water vapour with external supply of hydrogen gas and carbon dioxide gas into a first reverse conversion reactor, where the molar ratio of hydrogen gas to carbon dioxide gas is greater than one, in order to produce a first stream of synthetic gas which contains a mixture of at least carbon monoxide gas and hydrogen gas, water vapour and residual carbon dioxide gas; b) production of a second stream of synthetic gas from the first stream of synthetic gas through condensation and removal of at least a portion of water vapour from the first stream of synthetic gas; c) feeding the second stream of synthetic gas into a second water vapour reverse conversion reactor to produce a third stream of synthetic gas which contains a mixture of at least carbon monoxide gas and hydrogen gas, water vapour and residual carbon dioxide; d) production of a fourth stream of synthetic gas from a third stream of synthetic gas through condensation and removal of at least a portion of water vapour from the third stream of synthetic gas; and e) preparation of a mixture of at least hydrocarbon compounds from at least carbon monoxide gas and hydrogen gas from the fourth stream of synthetic gas. The invention also relates to a system for realising the said method.
EFFECT: use of the invention reduces power consumption on producing hydrocarbons from synthetic gas.
