Coal liquefaction study under the nonisothermal reaction temperature: Final report

Technical Report ·
OSTI ID:5638765
Kentucky No. 9 coal was soaked with 1-methylnaphthalene 60 minutes at 250/sup 0/C and 300/sup 0/C and liquefied with molecular hydrogen for 15 minutes at 380/sup 0/C to investigate effects of soaking temperatures on liquefaction in the presence of various hydrogen donor solvents. Coal liquefaction runs were conducted for both Kentucky No. 9 coal and Wyodak coal, increasing coal liquefaction temperatures from 200/sup 0/C or 300/sup 0/C up to 380/sup 0/C for 15 minutes to identify roles of hydrogen donor solvents in the early stages of coal liquefaction. Effects of reaction severity on liquefaction of coal in the presence of water were investigated. A series of coal liquefaction runs were conducted for Kentucky No. 9 coal, increasing coal liquefaction temperatures from 200/sup 0/C or 300/sup 0/C up to 380/sup 0/C. Objectives are (1) to investigate effects of reaction severity on coal liquefaction, (2) to understand roles of hydrogen donor solvents in the early stage of coal liquefaction, (3) to study effects of initial liquefaction temperatures on coal liquefaction, and (4) to evaluate effects of hydrogen donor solvents on product distributions in the early stages of liquefying Kentucky No. 9 coal at nonisothermal liquefaction temperatures. 16 figs., 5 tabs.
