Three operability tests for hydrocarbonization of Illinois No. 6 coal were conducted with encouraging results; remedial measures are planned for some problems encountered. Progress in support of in situ gasification continued on the matrix of planned experiments involving the pyrolysis of large blocks of bituminous coal. In the coal-solvent-hydrogen mixing project, fluid dynamics data for cocurrent upflow of air and coal slurry through the packed column were measured. Metallurgical analyses of test coupons exposed for 500 hr in the Fluidyne fluidized bed coal combustor have shown only slight to moderate corrosion. In the gas-fired potassium boiler project, all of design work and construction of equipment tower was completed. During the next several months, work will continue on the installation of piping, electrical wiring and heaters, and the instrument and control system, In the design studies of a coal-fired, alkali-metal-vapor topping cycle the first phase of a cycle analysis and the design and analysis of a metal vapor turbine were completed. The design of an atmospheric pressure fluidized bed furnace, the condenser-steam generator, and the layout work for the overall system is continuing. In the engineering studies evaluation project, work continued on: process modeling; preparation of a Synthetic Fuels Research Digest; a survey of industrial coal conversion equipment capabilities; and studies of fluidized bed hydrothermal liquefaction, rapid hydrogenation, hot gas cleanup, large air separation plants, and processes for heat recovery. In the process and program analysis project, studies continued on low-Btu gasification, high-Btu gasification, liquefaction, direct combustion, advanced power conversion, and coal beneficiation. The coal-burning gas turbine project has been reoriented to the development of technology for fluidized-bed coal combustion, closed-cycle gas turbine systems for potential industrial applications requiring heat and electrical energy.
