The objective of this project is to continue and advance pilot plant studies (initiated under prior contract) directed at the development of a commercial process for the production of pipeline-quality gas from coal; to demonstrate the feasibility of the HYGAS pilot plant to produce substitute natural gas using lignite, bituminous, and subbituminous coal feedstocks. Tests 62 and 63 were conducted during June. Test 62 lasted 3 days and was terminated because of operational problems in the product-gas quench system. Sixty-eight tons of pretreated coal were fed to the reactor. Test 63 included 7 days of self-sustained operation, and carbon conversions of around 80 percent. This test was terminated when it was impossible to transfer solids from the reactor and from the second-stage gasifier to the steam-oxygen gasifier. Modifications of the liquid-phase methanation unit to eliminate fire hazards were begun and should be completed next month. The quench system is being studied. Also, a cold-flow model is under construction to increase understanding of the initiation of solids flow to the steam-oxygen fluidized bed and the stability of the system to process transients.
