The COED process is the multistage fluidized-bed pyrolysis of coal. Product oil from the pyrolysis is hydrotreated to produce a synthetic crude oil. Project economics for a commercial COED plant, which also produces a marketable gas and a char, are attractive. A pilot plant was constructed to process 36 tons of coal per day in the pyrolysis section and 30 barrels of oil per day in the hydrotreating section. Both sections are in operation. The pilot plant will provide data for the design and economic analysis of a commercial COED plant, and the necessary oil and char samples for large-scale evaluations. Two pyrolysis runs, P-40 and P-41, were completed in November using Utah King coal with a nominal feed rate of 2250 lbs/hr. Run P-41 was the first pilot plant run feeding Utah coal with the oil absorber recovery system on line and the initial results were encouraging. The oil filter processed 307 barrels of Utah coal oil in November for hydrotreating unit feed and absorber start-up operations. High average filtration rates (9.7 gal/hr/ft/sup 2/) were again attained in these runs. The hydrotreating catalyst loading in the pilot plant reactors was replaced with fresh catalyst in November. Two material balance runs were made with the new catalyst system to continue the process variable studies with Utah and coal oil feed.
