Refining and upgrading of synfuels from coal and oil shales by advanced catalytic processes. Quarterly report, April-June 1984
This report gives results of our current studies on refining of integrated two-stage liquefaction (ITSL) process product to distillate fuels. The experimental program on ITSL Syncrude derived from Illinois No. 6 Coal is now complete. We studied the effect of ITSL syncrude end point on the severity necessary for hydrotreating to distillate products. Lummus provided Chevron with an additional barrel of ITSL process product (Illinois No. 6, Burning Star Mine) with an end point of about 800/sup 0/F to serve as feed. A 1080-hr pilot plant test was made with this feed and ICR 106 catalyst at 0.5 LHSV and 2300 psia hydrogen partial pressure. The new feed was harder to upgrade than the lower end point feed previously tested, but we were able to make 20 mm smoke point jet fuel at these conditions and 720/sup 0/F catalyst temperature. We made a 2385-hr second-stage hydrocracking pilot plant run in which hydrotreated ITSL oil was cracked to extinction over ICR 202 catalyst. It included series of tests to determine the quantity and quality of products produced at a variety recycle cut points (350/sup 0/F, 400/sup 0/F, 450/sup 0/F, 500/sup 0/F, 525/sup 0/F, and 550/sup 0/F). At 350/sup 0/F, the entire liquid product was naphtha. At higher cut points, products included a combination of naphtha and jet fuel. The smoke point of the jet fuel fraction met the specification of 20 mm at a cut point of 550/sup 0/F. At lower cut points, it exceeded 20 mm. 4 figures, 27 tables.
