Pipeline gas from coal-hydrogenation (IGT hydrogasification process). Project 9000 quarterly report No. 4, April 1--June 30, 1977
The technical feasibility of the HYGAS Process has been demonstrated by long, steady-state, pilot plant operation with lignite, bituminous, and subpituminous coals. With this program goal attained, the Institute of Gas Technology (IGT) is now concentrating on advanced process studies of the HYGAS Process using bituminous coal. Operating parameters necessary to obtain 90% carbon conversion with bituminous coals are being studied. This quarter, 90% carbon conversion was achieved for the first time, which was a significant step toward developing a commercially viable process. A study of minimum pretreatment conditions for producing nonagglomerating coal was begun. The pretreatment temperature was successively lowered in one series of tests. Because less severe pretreatment conditions mean that the coal contains more carbon when it enters the reactor--resulting in greater process efficiency--the investigation of these minimum conditions was another step toward achieving the goal of an economically viable coal gasification process. Four hydrogasification tests, Tests 60 through 63, were conducted this quarter with Peabody No. 10 mine bituminous coal.
