This report describes work performed in a program designed to further understand and improve the Solvent Refined Coal and related liquefaction processes. Considerable progress was made as four papers were finished for presentation at the Chicago meeting of the ACS Fuel Chemistry Division in August, 1977. These papers give the results of a Coulter Counter particle size analysis method for the SRC process, the effects of mineral matter on the hydrogenation/desulfurization reactions in the SRC process, a comprehensive model for the continuous SRC reactor/dissolver, and an X-ray fluorescence technique for SRC analysis. Other results include a detailed study of the effect of initial particle size of four coals used in the SRC process, an evaluation of additional coals in the visual reactor for SRC processability, experimental data showing the viscosity peaks present in the SRC preheater/dissolver and solubility of CO/sub 2/ and CH/sub 4/ in SRC recycle solvent.
