Conoco Coal research Division 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. The approach taken is to obtain analyses of a large number of well-defined process oils taken during periods of known operating conditions and known process performance. A variety of coal liquefaction process oils were dewaxes by variants of commercial processes in order to improve their quality as donor solvents. Twenty-five oils were analyzed from Hydrocarbon Research Incorporated's (HRI) Catalytic Two-Stage Liquefaction (CTSL) Run 227- 27. Ten microautoclave tests were made to ''calibrate'' the reactivity of our standard coal. Nineteen samples of coal and reaction products of coal and potassium/crown ether, supplied by Purdue University, were analyzed by infrared spectroscopy to derive quantitative and qualitative structural information. 22 refs., 13 figs., 38 tabs.
