FIELD: oil and gas industry.
SUBSTANCE: invention refers to the method involving synthesis gas obtaining stage at which raw materials of gaseous carbons contained in natural gas are subject to reforming in presence of catalyst with steam and/or carbon dioxide so that synthesis gas is obtained; stage for obtaining liquid hydrocarbons according to Fischer-Tropsch, at which synthesis gas is subject to effect in conditions of Fischer-Tropsch reaction in presence of catalyst so that Fischer-Tropsch reaction product is obtained; then, Fischer-Tropsch reaction product is divided into liquid hydrocarbons according to Fischer-Tropsch and gaseous products, and upgrading stage at which the hydrocarbon product according to Fischer-Tropsch is subject to hydraulic cleaning in presence of catalyst so that hydraulically cleaned product is obtained; then, hydraulically cleaned product is refined so that light hydrocarbons and kerosene and gas oil end products are obtained where at least some part of light hydrocarbons separated by means of refining at the above upgrading stage is recycled to the above stage for obtaining synthesis gas as part of raw materials of gaseous carbons.
EFFECT: light hydrocarbons representing a byproduct having low added value can be reused, and the basic unit of raw materials can be improved.
