Method for obtaining carbohydrogens and / or oxygenates

Abstract

The invention relates to the field of organic chemistry, in particular to a method for the synthesis of hydrocarbons and their oxygenates in the presence of a cobalt-manganese-containing Fischer-Tropsch synthesis catalyst. The claimed method is carried out in the following stages: - a methane synthesis mixture containing hydrogen and carbon dioxide is brought into contact with a methane synthesis catalyst, so that the methane synthesis catalyst contains from 2 wt. % to 20 wt. % on an elemental basis to ensure the flow of methane product. % cobalt and 0.5 wt. % to 15 wt. % manganese; - at least a portion of the methane from the methane product stream is passed to a reforming feedstock containing aqueous methane and / or oxygen; - the reforming feedstock is reformed to produce a reforming product stream containing carbon monoxide and hydrogen; and - contacting the mixture for the synthesis of hydrocarbons containing hydrogen and carbon monoxide with a Fischer-Tropsch hydrocarbon synthesis catalyst, wherein the mixture for the synthesis of hydrocarbons includes at least a portion of the reforming product stream, for example, with a selectivity for C5+ hydrocarbons of at least 50% and / or a selectivity for oxygenates of at least 20%, to obtain a hydrocarbon product stream containing C5+ hydrocarbons and / or oxygenates.
