The main effort was directed toward the shakedown runs in the PDU. A number of equipment problems surfaced which have been, or are being, corrected. The combustion system has been operated successfully, and some short runs have been made in which both liquids and gases have been produced. Longer runs at hydrogen-to-coal ratios of 0.2 to 0.3 will be made during the forthcoming quarter. From work done in the bench-scale unit it has been found that a large fraction of steam in the carrier gas significantly alters the distribution of carbon among products. Carbon oxide yields are increased and hydrocarbon liquid yields are decreased; ethane yields were essentially unchanged, and methane yields were decreased slightly. An equipment flow sheet for a commercial hydropyrolysis plant for producing fuel gases, blending gasoline constituents, and fuel oil from coal has been developed and is being used as a base case for process analysis. A number of processing options have become apparent that will require a further analysis before estimates of total plant investment and selling prices of products can be completed.
