OSTI ID:6313720
A fuel for a carburetor type engine consisting essentially of isobutene oligomers and methyl tert.-butyl ether, said fuel prepared by a process comprising: (A) in a first step contacting a mixture of straight chain and branched butanes and butenes with an acid catalyst whereby to oligomerize 50% to 90% by weight of the isobutene contained therein: (B) contacting the reaction mixture from step (A) with at least a molar amount of methanol, relative to the residual isobutene, in the presence of an acid catalyst; and (C) separating off from the reaction mixture unreacted butanes and butenes.
