Laboratory-scale screening tests were carried out on PSOC 276, Pittsburgh Coal from Harrison County, Ohio to establish chlorination and hydrodesulfurization conditions for the batch reactor production of chlorinolysis and chlorinolysis-hydrodesulfurized coals. In addition, three bituminous coals, Pittsburgh No. 8 from Greene County, PA, Illinois No. 6 from Jackson County, Illinois and Eagle No. 5 from Moffat County, Colorado were treated on the lab scale by the chlorinolysis process to provide 39 to 62% desulfurization. Two bituminous coals (PSOC 276, Pittsburgh Coal from Harrison County, Ohio and 282, Illinois No. 6 Coal from Jefferson County, Illinois) and one subbituminous coal (PSOC 230, Rosebud Coal fom Rosebud County, Montana) were then produced in 11 to 15 pound lots as chlorinolysis and hydrodesulfurized coals. The chlorinolysis coals had a desulfurization of 29 to 69%, reductions in volatiles (12 to 37%) and hydrogen (6 to 31%). Hydrodesulfurization provided a much greater desulfurization (56 to 86%), reductions in volatiles (77 to 84%) and hydrogen (56 to 64%). The three coals were combustion tested in the Penn State plane flame furance to determine ignition and burning characteristics. All three coals burned well to completion as: raw coals, chlorinolysis processed coals and hydrodesulfurized coals. The hydrodesulfurized coals experienced greater ignition delays and reduced burning rates than the other coals because of the reduced volatile content. It is thought that the increased open pore volume in the desulfurized-devolatilized coals compensates in part for the decreased volatiles effect on ignition and burning. 4 figures, 2 tables.
