METHOD AND APPARATUS FOR PRODUCING METHANOL WITH HYDROGEN RECIRCULATION Russian patent published in 2011 - IPC C07C29/48 C07C31/04 C07C47/48 C07C27/12 B01J12/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing methanol, involving feeding a first stream of hot hydrocarbon-containing gas into a reactor, feeding an oxygen-containing gas into the reactor, oxidation of the hot stream of hydrocarbon-containing gas in the reactor with oxygen from the oxygen-containing gas to form a stream of products containing methanol and formaldehyde; and transferring heat from the stream of products to the first stream of hydrocarbon-containing gas, extracting methanol from the stream of products and extracting CO₂ and formaldehyde from the stream of products to form a reduced stream of products containing hydrocarbons through physical absorption thereof with an absorbent, wherein the first stream contains at least a portion of the reduced stream of products, as well as apparatus (versions) for realising said method.

EFFECT: invention enables to obtain an end product using an efficient and cheap method.
