A table is presented, which shows a comparison of conditions and results of hydrogenation of Scholven coal at 300 and 700 atm. Advantages of the conversion to the higher pressures were: catalysts could be used which contained no scarce metals, did not attack the converter by corrosion, and were cheaper. A higher reaction temperature might be used with consequent higher production, a somewhat greater decomposition and particularly a decrease in the asphalt produced, which assured a trouble-free processing of the residue. In spite of the higher temperature, gasification was decreased. Another table is included, which shows the processing conditions and the most important results of the liquefaction of Silesian bituminous coal by various processes. From the gasoline plus middle oil process through the 30 and 50% heavy oil processes to the extracting hydrogenation at approximately equal reaction temperatures the conditions changed in stages with respect to: increase in coal throughput, decrease in heavy oil content of the pasting oil (which must be partly compensated by an increased let-down return), decrease in H/sub 2/ supply, and saving of Bayermasse and sulfigran in extracting hydrogenation, with consequent better filterable let-down. The effects of these changes were the following: the throughput, the oil yield based on input coal, and the heavy constituents of the oil yield, such as asphalt, decreased, but equal boiling fractions also became heavier and H/sub 2/ -poorer. Gasification and, to a certain degree, decomposition decreased. 2 tables.
