Abstract
A continuous process for recovery of acetylene-free gaseous mixture from gaseous feedstreams containing acetylene and optionally other low molecular weight hydrocarbons by contacting the acetylene-containing feedstream with an alkanol in combination with a super acid catalyst, Lewis acid, Bronsted acids, or mixtures thereof, under conditions of reaction sufficient to form a mixture containing at least one acetal organic compound, and a gaseous product substantially free of acetylene. Preferred catalysts include boron trifluoride in methanol with mercuric oxide. Processes according to the invention are, advantageously, used for recovery of acetylene-free gaseous mixture from gaseous feedstreams containing a mixture of acetylene, a synthesis gas comprising dihydrogen and carbon monoxide, and optionally one or more members of the group consisting of dimethyl ether, formaldehyde, ethylene, and propylene.
