NOVEL, HIGHLY EFFICIENT ECO-FRIENDLY PROCESSES FOR CONVERTING CO2 OR CO-RICH STREAMS TO LIQUID FUELS AND CHEMICALS

The invention provides a process for preparing liquid fuels and chemicals, which process comprises feeding carbon monoxide and hydrogen to a hydrogenation reactor, wherein the molar ratio CO:H2 is in the range of 1:0.5 to 1:0.9, catalytically hydrogenating said carbon monoxide in said hydrogenation reactor, condensing the effluent of said hydrogenation reactor to recover one or more organic liquid(s) and an aqueous solution, feeding a non-condensable component of said effluent into an oligomerization reactor; condensing an effluent discharged from the oligomerization reactor to obtain an additional organic liquid and an additional gaseous stream, separating said additional organic liquid, and either combusting said additional gaseous stream to produce heat and electricity, or processing same to obtain recyclable gaseous streams utilizable in said process.
