Abstract
Abstract A synthetic fuel formulation is disclosed, together with a process of producing such synthetic fuel. Based on its total weight, the fuel is comprised of approximately fifty to about seventy-five percent of an aliphatic hydrocarbon alcohol containing two to eleven carbon atoms, about five to twelve percent water, approximately two or twenty weight percent of a solvent for the alcohol, and about one to about seven weight percent of a hydrocarbon glycol, acetone, and methyl ethyl ketone. Optional ingredients may also be included, such as anti-rust and anti-foaming agents, as well as an agent to increase the storage life of the fuel. To produce such synthetic fuel, the foregoing ingredients are mixed sequentially, starting with the alcohol and adding thereto the solvent, acetone, optional agents if utilized, methyl ethyl ketone, the glycol, and water.
