METHOD OF COMBINED METHANOL AND AMMONIA PRODUCTION FROM INITIAL HYDROCARBON RAW MATERIAL Russian patent published in 2014 - IPC C01C1/04 C01B3/02 C07C31/04 

FIELD: chemistry.

SUBSTANCE: invention can be used in the chemical industry. A method of the combined methanol and ammonia production from an initial raw material is realised by means of the following stages. First, synthesis-gas of the methanol production, which contains hydrogen, carbon oxides and nitrogen, is obtained by steam reforming of an initial hydrocarbon raw material at the first stage of reforming and then at the second stage of reforming with air blast. After that, carried out are: catalytic conversion of the synthesis-gas carbon and hydrogen oxides at a single-pass stage of methanol synthesis and the discharge of the methanol-containing output product, and an effluent gas flow, containing nitrogen, hydrogen and non-converted carbon oxides. The non-converted carbon oxides of the gas flow from the preceding stage are removed by hydrogenation to methane at the stage of the catalytic methanation with the formation of synthesis-gas, which has a molar ratio H₂:N₂, equal 3:1. Ammonia is synthesised by the catalytic conversion of nitrogen and hydrogen, with the discharge of the ammonia-containing product and effluent gas flow, containing hydrogen, nitrogen and methane.

EFFECT: claimed invention provides the creation of a simple and cheap method of the combined production of methanol and ammonia.
