FIELD: petrochemical processes. SUBSTANCE: natural and oil-associated gases are catalytically processed into liquid hydrocarbons via process including catalytic conversion of feedstock and recycling streams using air and high-temperature raw material to form synthesis-gas subjected further to catalytic processing giving rise to liquid hydrocarbons. Remaining gas products are subjected to after-burning to give combustion products, from which carbon dioxide is isolated. Method is distinguished by additionally including low-temperature conversion of mixture composed of recycling gaseous synthesis products and carbon dioxide isolated from combustion products. In the course of low-temperature conversion, carbon dioxide is catalytically reduced into carbon monoxide and water with participation of hydrogen contained in the mixture. Resulting products are either introduced into synthesis-gas subjected to further to catalytic processing or are divided into two portions, one of which is combined with oil feedstock subjected then to conversion and the other is added to synthesis-gas subjected then to catalytic processing. EFFECT: reduced power consumption and increased yield of liquid hydrocarbons. 9 cl, 2 dwg
