97/00835 Coal liquefaction: PDU-scale testing at Hydrocarbon Technologies Inc

Abstract

Liquefaction of Illinois No. 6 bituminous and Wyoming Black Thunder sub-bituminous coal was successfully demonstrated in two test runs at a processing rate of 3 TPD at the Proof-of-Concept (POC) facility in Lawrenceville, NJ using HRI`s Catalytic Two-Stage Liquefaction (CTSL{trademark}) Technology. The POC Program is funded by the US DOE, Hydrocarbon Research Inc., and Kerr McGee Corporation. In the CTSL{trademark} process the first stage reactor operates at lower temperature (385--415 C) to hydrogenate the coal and recycle oil while the second stage operates at a higher temperature (425--440 C) to convert the coal and heavy oils to clean distillate products. Kerr McGee`s ROSE-SR{sup SM} solids separation technology was demonstrated during these two test runs. The Illinois coal run achieved operation with a concentrated slurry of 0.9 to 1.0 oil/coal ratio and achieved results up to 74% MAF C{sub 4}-524 C, 524 C conversion of over 85% MAF and coal conversion up to 96% MAF coal. The Wyoming coal run achieved operation with a slurry feed of 1.2 oil/coal ratio and achieved results up to 66% MAF C{sub 4}-524 C, 524 C conversion of over 86% MAF and coal conversion up to 93.5% MAF coal and IBP-360 C distillate quality ofmore » 3 ppm sulfur and 21 ppm nitrogen with on-line hydrotreating. In addition the Wyoming coal run processed 12 tons of combined plastic and coal feed and 5 tons of combined waste rubber tire and coal feed.« less
