Laboratory Program to Support H-Coal Pilot Plant Operations. PDU Run 6:Syncrude Mode Operating Using Wyodak Coal.

摘要

PDU 6was a thirty-day run in the H-Coal syncrude mode using Wyodak coal. It simulated the planned operating conditions for Run 3of the H-Coal Pilot Plant Technical Management Plant. The major achievements and observations from this milestone run are summarized. This is the first PDU operation in which Wyodak coal was successfully processed in a balanced syncrude mode with an equilibrated catalyst bed as in the Pilot Plant. Coal conversion was higher than Pilot Plant design,from 91to 93.5% of MAF coal feed and the C sub 4 -975exp 0 F distillate yield equilibrated at 45 W % of dry coal in operations with a catalyst replacement rate of 1.1lbs/ton of coal. A yield of 50% C sub 4 -975exp 0 F distillate was obtained in early operations of the run. The equilibrated distillate yield level was about 2 W % below the Pilot Plant design basis with gas yield 3% higher. After the 30-day run,the catalyst was removed in a free flowing condition with no agglomeration or evidence of calcium induced deposits. (ERA citation 04:044228)
