Thermal and catalytic coprocessing of coal and waste materials
- Univ. of Utah, Salt Lake City, UT (United States); and others
Coprocessing of coal with waste materials to produce liquid fuels with emphasis on determining reasonable reaction pathways and catalysts for such processing is presently the subject of intensive investigation. Previous work by us and others indicates that both thermal and catalytic reactions must be utilized to achieve direct liquefaction. Kinetic studies of the coprocessing of coal, rubber tires and commingled plastic were performed at different reaction temperatures and times. DECS 6 (Blind Canyon Coal, Penn State Coal Sample Bank), a high volatile bituminous coal, was tested with pure polymers, rubber tire materials, and commingled plastic. Results shows that coprocessing of coal/commingled plastic can be achieved at relatively high reaction temperatures and reasonable reaction times. Coprocessing of waste rubber tires with coal in the presence of a molybdenum catalyst and hydrogen gas at 350{degrees}C and 430{degrees}C will be reported. The significance of the results for understanding coal/waste coprocessing reactions are discussed.
