Description
Summary:Fischer−Tropsch conversion of natural gas to liquid hydrocarbon fuel typically includes Fischer−Tropsch synthesis followed by refining (hydrocracking and distillation) of the syncrude into mostly diesel or kerosene with some naphtha (a feedstock for gasoline production). Refining is assumed necessary, possibly overlooking the exceptional fuel qualities of syncrude for more direct utilization as a compression−ignition (CI) fuel. This paper evaluates cetane number, viscosity, cloud-point, and pour-point properties of syncrude and blends of syncrude with blend stocks such as ethanol and diethyl ether. The results show that blends comprised primarily of syncrude are potentially good CI fuels, with pour-point temperature depression being the largest development obstacle. The resulting blends may provide a much-needed and affordable alternative CI fuel. Particularly good market opportunities exist with Environmental Policy Act (EPACT) applications.
