The purpose of this research program is to develop an improved method for producing a highly effective solvent for the Integrated Two-Stage Liquefaction (ITSL) process and to study the characteristics of the solvent at a variety of process conditions. The ITSL process for conversion of coal to distillate liquids combines Short Contact Time (SCT) hydroliquefaction and expanded bed hydrogenation and hydrocracking of the coal extract, either before or after deashing. Experimental microautoclave work in Subtask 2.3 (solvent hydrocracking with catalysts) was completed. A total of fourteen catalysts were tested from which six were chosen for further evaluation in Subtask 3.2. The six catalysts are: Shell 324 Mod. Ni/Mo; Shell 317 Ni/Mo; American Cyanamid Beaded Co/Mo; Katalco NM-506 Ni/Mo; American Cyanamid 1442B Co/Mo; and Procatalyse HT-841 Ni/Mo. Scheduled microautoclave work in Subtask 3.2 (coal extract and solvent hydrogenation) was completed. Initial results show that the quality of the hydrogenated product, based on hydrogen content, depends primarily on the hydrogen content of the SCT paste solvent which made the extract feedstock to Subtask 3.2. The choice of catalyst in the hydrotreater and the severity of the SCT extract production step were of lesser significance to the quality of the hydrogenated product. The catalytic reactor conditions also are of great importance in product quality and may be used to adjust the hydrogen content of an insufficiently hydrogenated or overly hydrogenated recycle paste solvent stream. 2 figures, 10 tables.
