权利人:BOLTON LESLIE W; GRACEY BENJAMIN P; BP CHEM INT LTD
摘要:Process for converting carbon oxide(s) and hydrogen containing feedstocks to oxygen containing hydrocarbon compounds, in the presence of a particulate catalyst, by reacting carbon oxide(s) and hydrogen in the presence of a particulate catalyst in a conversion reactor to form products containing oxygen containing hydrocarbon compounds. Ether(s) selected from ethyl, propyl and butyl ether are added and reacted inside the conversion reactor.
