Coal desulfurization by low temperature chlorinolysis was conducted by the Jet Propulsion Laboratory, California Institute of Technology. An engineering scale batch reactor system was constructed and operated for the evaluation of five high sulfur bituminous coals obtained from Kentucky, Ohio and Illinois. Forty-four test runs were conducted under conditions of 100 x 200 mesh coal, solvents - methylchloroform and water, 60 to 130/sup 0/C, 0 to 60 psig, 45 to 90 minutes and gaseous chlorine flow rate of up to 24 SCFH. Sulfur removals demonstrated for the five coals were: maximum total sulfur removal of 45 to 66%, pyritic sulfur removals of 71 to 95% and organic sulfur removal of 46 to 89% (4 of 5 coals with methylchloroform) and 0 to 24% with water. In addition, an integrated continuous flow mini-pilot plant was designed and constructed for a nominal coal feed rate of 2 kilograms/hour which will be operated as part of the follow-on Phase III program. Equipment flow sheets and design drawings are included for both the batch and continuous flow mini-pilot plants.
