Consolidation coal Research and Development is characterizing samples of direct coal liquefaction process oils based on a variety of analytical techniques to provide a detailed description of the chemical composition of the oils, to more fully understand the interrelationship of process oil composition and process operations, to aid in plant operation, and to lead to process improvements. A set of 23 oils from Hydrocarbon Research, Inc., (HRI) was analyzed to provide information on the performance of Burning Star No. 2 mine (Illinois 6) bituminous coal, in the ''demonstration'' run of the Catalytic Two-Stage Liquefaction (CTSL) process. Two feed coals (cleaned and uncleaned Ohio 5/6) for HRI CTSL were analyzed. A set of microautoclave experiment was made to determine the potential benefits of a low-temperature pretreatment on donor liquefaction yields. Samples of nitric acid treated North Dakota lignite, produced at four sets of reaction conditions by JGS Research Co., Inc., were analyzed. Three cal products from Purdue Resarch Foundation were characterized by FTIR for chemical and structural information. We have composited the individual oil sampels obtained from various PDU and pilot plan runs. Two earlier reports included results obtained from the analysis of oils produced in the Signal Research/UOP continuous coal/petroleum coprocessing unit. Some of those yield data were incorrect. All appropriate re-calculations were performed. 45 refs., 32 figs., 17 tabs.
