System for the manufacture of methanol and simultaneous abatement of emission of greenhouse gases

摘要

A method for the joint i) abatement of emission of a "greenhouse" gas by removing carbon dioxide from an effluent and ii) manufacture of methanol by reaction of hydrogen with carbon dioxide which includes: a) reacting carbon dioxide in the effluent by flowing contact of the effluent with a bed of basic metal oxide at a temperature suitable to form a metal carbonate, b) then stopping the effluent flow after said bed has become substantially converted to the carbonate, c) heating the carbonate to a temperature suitable to release carbon dioxide, d) then mixing the released carbon dioxide with hydrogen while passing the mixture over a catalyst of another metal oxide at a suitable temperature and pressure for a reaction, and thereby forming methanol.
