This bench-unit program simulated the Catlettsburg H-Coal Pilot Plant start-up procedure in Run 6, which used catalytic cracker slurry oil, an aromatic petroleum oil. These included a catalyst tracer study in conjunction with Sandia Laboratories tests on letdown valve trims for Battelle a fluid dynamics study with Amoco and special high-pressure liquid sampling for the Oak Ridge Laboratory. Four additional studies were successfully completed during PDU 10. Microautoclave testing was introduced as an operational aid. Steady operations at more » lower oil/solids ratios were demonstrated. High hydroclone efficiency and high solids content in the vacuum still were maintained throughout the run. PDU 10 achieved improved yields and lower hydrogen consumption compared to PDU 6, a similar operation. Amocat 1A catalyst was qualified for Pilot Plant operation based on improved operation and superior performance. Targeted coal conversion of 90 W % was exceeded with a C/sub 4/-975/sup 0/F distillate yield of 43 to 48 W%. PDU Run 10, a 46-day H-COAL syncrude mode operation using Wyodak coal, successfully met all targeted objectives, and was the longest PDU operation to date in this program. Steady operations more » at lower oil/solids ratios were demonstrated.
