EDS Coal-Liquefaction Process Development. Phase V. Quarterly Technical Progress Report for the Period October 1-December 31, 1981

摘要

Operation of the recycle liquefaction units and the coal liquefaction pilot plant with various coals is reported giving yields and product data. Solvent hydrogenation studies at low process pressure (900 psig) showed that the severity of hydrogenation at these conditions decreased in agreement with the model of hydrogenation. Combustion tests of coal-derived fuels were performed in a 1450 hp boiler. Fractionation and hydrogenation of coal liquids was carried out to prepare experimental gasoline blending stock and diesel fuels (with cetane improvers). Experiments involving radioactive tracers were carried out to get data on holdups, residence time and the degree of backmixing needed for plant engineering and design. Other operations are discussed briefly. (ERA citation 07:041993)
