METHOD OF METHANOL SYNTHESIS Russian patent published in 2009 - IPC C07C31/04 C07C29/151 C07C27/06 C07C29/145 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining methanol from feeding flow enriched with hydrogen, carbon monoxide and carbon dioxide. Method includes: (a) contacting of feeding flow with methanol synthesis catalyst and obtaining technological flow which contains methanol, aldehides and ketones and unconverted hydrogen, carbon monoxide and carbon dioxide, (b) cooling of obtained technological flow to temperature between 20° and 200°C, (c) contacting of cooled technological flow with hydrogenisation catalyst active in reaction of aldehide and ketone hydrogeniosation into corresponding alcohols and obtaining technological flow enriched with methanol and depleted of aldehides and ketones, (d) cooling and condensation of technological flow enriched with methanol and depleted of aldehides and ketones, and separation of stage (d) technological flow into gas phase and liquid phase with raw methanol.

EFFECT: ensuring efficient obtaining methanol from feeding flow, enriched with hydrogen, carbon monoxide and carbon dioxide.
