- W122121502 abstract "Non-catalytic liquefaction of West Virginia (Ireland Mine) coal in creosote oil was studied in a four stage, packed continuous reactor. Reactor conditions included 425/sup 0/C, 4000 psi, liquid space velocities of 140 to 1600 lbs/h-ft/sup 3/ and gas rates of 260 to 2800 MSCF/ton of coal to bracket conditions used in the SYNTHOIL preheater. Gas flow rates had no significant effect on the coal liquefaction processes. Preasphaltene content and the viscosity of the coal liquid increased rapidly early in the reactor; feed of this high preasphaltene product into a subsequent catalytic reactor could lead to plugging and coking. Approximately 50 percent of the sulfur was removed rapidly and little additional removal occurred at low liquid space velocities. Over 90 percent of the organic matter in the coal was converted to THF soluble products and over 70 percent to benzene soluble products at liquid space rates below 150 lbs/h-ft/sup 3/. At these low rates, the hydrogen/carbon ratio of the product and gas formation also increased. The data shows qualitatively the reactions occurring in preheaters for coal liquefaction plants; specifically the packed preheater for the SYNTHOIL Process. Residence time data needs to be obtained to provide quantitative engineering design data." @default.
