FIELD: chemistry.
SUBSTANCE: method of preparing a mixture of hydrogen and carbon monoxide from a gaseous mixture of hydrocarbons containing methane, ethane and optionally hydrocarbons with a large number of carbon atoms involves the following steps: (a) preliminary reforming of the mixture of hydrocarbons in the presence of a suitable reforming catalyst with conversion of ethane and optionally hydrocarbons with a large number of carbon atoms to methane, carbon dioxide and hydrogen, (b) heating the gaseous mixture obtained at step (a) to temperature of 750-900°C, (c) partial oxidation by bringing the heated mixture obtained at step (b) into contact with an oxygen source in the burner of the reactor to obtain a reaction stream. The mixture of hydrogen and carbon monoxide obtained at step (c) is used at step (d) for Fischer-Tropsch synthesis, in which gas containing hydrogen and carbon monoxide obtained at step (c) is converted at one or more steps at least partially to liquid hydrocarbons in the presence of a Fischer-Tropsch type catalyst which contains at least one metal or a metal compound selected from group eight of the periodic table of elements.
EFFECT: invention reduces oxygen consumption.
