About 6.7 tons of vacuum tower bottoms (residue) which were obtained during the liquefaction of Illinois No. 6 coal from the H-Coal liquefaction process pilot plant at Catlettsburg, Kentucky were successfully gasified at Texaco's Montebello Research Laboratory. The single 9.5-hour run with H-Coal liquefaction residue-water slurry was completed at 750 to 760 psig gasifier pressure. The run consisted of two test periods, each at a different gasifier temperature. Over 99.6 percent conversion of carbon in the feed to syngas was achieved yielding 32.9 to 33.7 standard cubic feet of dry syngas per pound of residue charged. The oxygen requirement was about 1.0 pound of oxygen per pound of residue. The dry syngas contained 78.5 to 79.7 (vol.) percent carbon monoxide plus hydrogen.
