Several modifications were made in the bench scale hydrocarbonization system in an attempt to develop a procedure for handling of caking coals. Experimental work on the pyrolysis of large blocks of coal, on pressurized carbonization of residues, and on three-phase mixing was continued. Impact testing of 10-in.-thick pressure vessel steel disclosed major gradients in impact properties. Development of a variety of methods for nondestructive testing of wear- and process-resistant coating was continued. The development of welding techniques for cladding of carbon steels with Alloy 320 stainless steel has been successful. A microprobe examination of high alloy steel tubes that had been exposed in a fluidized bed combustor for 500 hr revealed about 0.001-in.-thick scales of predominantly calcium sulfate. In the gas-fired potassium boiler project design, fabrication, and installation of equipment needed for initial operations with potassium was continued. Similarly, the design study of a coal-fired boiler for an alkali metal vapor topping cycle was continued. Engineering study and technical support work continued with activities in process modeling; a survey of industrial coal conversion equipment capabilities; and studies of processes for heat recovery, rapid hydrogenation, and purification of hot gas. Process and program assistance work included studies on low-Btu gasification, high-Btu gasification, liquefaction, direct combustion, advanced power conversion, and in-situ gasification of coal.
