Hydrocarbonization run HC-25 was completed using Wyodak coal at a lower system pressure (150 psig) than used in previous runs to obtain information on the effect of pressure on yields. The run proceeded smoothly with no interruption of feed or other difficulties. In support of in situ gasification, block pyrolysis experiments BP-42 and -43 were conducted at 0.3/sup 0/C/min reaching surface temperatures of 900 and 1000/sup 0/C, respectively. The toughness of 2/sup 1///sub 4/ Cr-1 Mo in thick sections suitable for large coal conversion systems is being explored in the pressure vessel and piping materials work for material in the as-fabricated condition. Equipment modification for plasma spraying of CoCrAlY have been completed in the coatings inspection program. In the welding and cladding program, a range of welding parameters has been found for depositing type 320 Cb stainless steel on carbon steel clad with Inconel 82 that produces no cracking on the finished surface. The corrosion data from the fireside corrosion tests for types 304, 316, and 310 stainless steel, Alloy 600, and Alloy 800 exposed to the Fluidyne atmospheric fluidized bed combustor for 500 hr and 1500 hr are summarized. High-temperature specimens for a 3000 hr run have been prepared. A failure analysis of heat exchanger tubes from the Morgantown Energy Research Center fluidized bed combustor and progress in examining corrosion surveillance coupons from the Wilsonville, Alabama, solvent refined coal plant are reported. In the gas-fired potassium boiler experiment, about 5 hr of stable boiling operation was obtained at power levels up to about 3.5 x 10/sup 6/ Btu/hr. An evaluation was initiated of an in-situ facility for producing methanol which would then be converted to gasoline via the Mobil-M process. An effort was also initiated to develop a computer model for the HYGAS gasifier.
