Abstract : A cooperative demonstration program between industry and the Department of Energy yielded a sizable quantity of coal derived, mid distillate fuel producted by the Exxon Donor Solvent (EDS) process. Eighty-three 55-gallon drums of this product were made available to the Belvoir Fuels and Lubricants Research Facility at Southwest Research Institute for evaluation through the U.S. Army Belvoir Research, Development and Engineering Center, Ft. Belvoir, VA. The EDS mid-distillate was characterized in the laboratory for chemical and physical properties, and evaluated in a medium-speed diesel engine. Due to the low cetane number, toxicity, poor storage/thermal stability, and incompatibility with elastomers, this fuel was not evaluated as received in the normal operation of diesel engines. A 69/31 blend of the EDS mid-distillate and a petroleum-derived diesel fuel was used with relative success in a medium speed diesel engine. A similar blend evaluated in single-cylinder diesel engine burned less efficiently than the petroleum fuel.
