Summary
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. 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 set of two feed coals and 45 oils from Wilsonville Run 254 were analyzed to provide information on the performance of these coals in catalytic/catalytic operation in close-coupled integrated two-stage liquefaction (CC-ITSL) with ash recycle. Oils from Wilsonville Run 254 were dewaxed to evaluate any improvement on donor solvent quality. One oil from Wilsonville Run 254 was distillated both at Consol and at Wilsonville using their respective distillation procedures. The distillation fractions were analyzed. Carbon isotope ratios were determined on the two planned feedstocks for Wilsonville Run 255 (Ohio 6 coal and Martin Lake lignite). Three microautoclave tests were made to access the donor liquefaction reactivity of Elkhorn 3 coal. Sixteen microautoclave tests were made to ''calibrate'' the reactivity of our standard coal. Six microautoclave tests were made with two oils from Wilsonville Run 254 to determine the reproducibility of microautoclave tests as applied to samples containing high concentrations of solids. A series of ten fluid-coker tars, produced by Lummus-Crest, Inc., from coal liquefaction vacuum bottoms, was characterized to evaluate their use as liquefaction recycle oils. 11 refs., 26 tabs.
