FIELD: chemistry.

SUBSTANCE: present invention relates to the method for producing paraffinic products from carbon raw materials. The method involves the partial oxidation of carbon raw materials to produce a mixture containing hydrogen and carbon monoxide, the implementation of the Fischer-Tropsch synthesis using the obtained mixture and recovery of paraffinic product and exhaust gas, hydrogenation of at least part of the exhaust gas from the Fischer-Tropsch reaction, optionally after removing hydrocarbons using a molar ratio of steam to exhaust gas in the range of from 0.5 to 1.5, and the catalyst containing copper and zinc, or a catalyst containing copper, zinc and manganese, convertion of at least part of the formed gas, using a catalyst based on nickel which contains not more than 0,2 wt % of cobalt, not more than 0,2 wt % of iron and not more than 0,2 wt % of ruthenium, per total weight of the catalyst and obtaining a hydrogen-containing gas from at least part of the obtained gas using reforming, steam reforming, methane/water steam reforming, adiabatic steam reforming, steam reforming with flame heating or autothermal steam reforming.

EFFECT: invention provides an optimized method for producing the paraffinic product, as well as increase of catalyst service life.
