Continuous bottoms recycle operations continued in the 50 pound-per-day Recycle Coal Liquefaction Unit. Yield data were taken at 60 minutes nominal liquefaction residence with Pittsburgh No. 8 bituminous coal (Ireland Mine) on the one ton-per-day Coal Liquefaction Pilot Plant (CPP). Operations with Ireland mine coal continued to be good. In addition, construction of the bottoms recycle modification was completed on the CLPP and shake-down operations were started. The Ni/Mo-10 catalyst activity maintenance study completed 13 days-on-solvent. A series of experiments on the Continuous Stirred Coking Unit (CSCU) is underway to determine the effect of reduced temperature and feed dilution on coker yields. These runs, as is the FBU study, are being made to test the feasibility of operating the FLEXICOKING prototype unit at reduced temperature to determine the effect of operating near the bogging limit on bed fines retention. Work began on an engineering screening study to evaluate the value of coal liquids products from an EDS plant. A range of product value scenarios are being developed from public sources. These scenarios will be used to determine the effect on net cash flow and process configurations for the coals studied to date. Sensitivities to the Market Flexibility Case RISP were developed to illustrate the effects of various possible government incentives designed to stimulate the development of the synthetic fuels industry.
