METHOD OF METHANOL OBTAINING Russian patent published in 2008 - IPC C07C31/04 C07C29/154 

FIELD: chemistry.

SUBSTANCE: invention pertains to the method of methanol obtaining from a concentrated mixture of hydrogen and carbon oxides with the following components in vol %: H₂ - 62.0-78.5; Ar - 0.02-0.07; N₂ - 0.05-2.2; CH₄ - 1.0-3.5; CO - 10.4-29.5; CO₂ - 3.2-10.7. The methanol is obtained by concentrating it in a copper containing catalyst at high temperature and pressure in two stages. The gas mixture from the reformer is divided into two streams in volume ratios of 100 : (1-50), one of which is in direct contact with the catalyst in the flow reactor at the first stage, at temperature of 200-285°C, pressure of 5-15 MPa and volume rate of 800-2000 h^-1. The other stream is mixed with a cycled gas in volume ratio of 10 : (10-100) and with volume rate of 2500-10000 h^-1. This stream is then channelled to the second stage, with separation of methanol and water on each stage in corresponding devices.

EFFECT: increased production of methanol and increased efficiency of the process.
