In a continuing program to upgrade solvent refined coal (SRC-1) supported by the U.S. Department of Energy, runs made in LC-Fining laboratory process development units of the C-E Lummus Co. with commercially available catalysts demonstrated that the proportion of solvent can be reduced from 50 to 30%; processing with a higher boiling range solvent increases conversion and denitrogenation; a Wyoming coal from the Amax Belle Ayr mine can be processed; and operations with cool noncatalytic zones yield a lower over-all conversion but identical denitrogenation. A distillate product (390/sup 0/-850/sup 0/F) contained 0.3% nitrogen. The conversion of 850/sup 0/F+ is essentially thermal whereas denitrogenation and desulfurization are catalytic.
