Gasification of residual materials from coal liquefaction: Type II preliminary pilot-plant evaluation of molten H-Coal liquefaction residue
About 5.5 tons of vacuum tower bottoms (residue) obtained from 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 on January 16-17, 1982. Two test runs with molten H-Coal liquefaction residue were completed, each at a different operating temperature. The conversions of carbon in the feed to syngas achieved during the two test runs were 99.4 and 98.6 percent, yielding 35.2 and 35.5 standard cubic feet of dry syngas per pound of residue feed. The oxygen requirement was about 0.8 pound of oxygen per pound of residue for each run. The dry syngas contained about 93.4 (vol.) percent carbon monoxide plus hydrogen. The two short pilot unit runs did confirm the operability of the Texaco Synthesis Gas Generation Process with this feedstock, and the data obtained confirm earlier predictions of performance efficiency. A comparison of the gasification efficiency of molten H-Coal liquefaction residue with the gasification efficiency of H-Coal liquefaction residue-water slurry revealed that the molten process was more efficient. The molten system required less oxygen for gasification, 0.78 versus 1.00 pounds of oxygen per pound of residue, and produced a greater volume percent carbon monoxide plus hydrogen in the product syngas, 93.4% versus 79.2%, than the residue-water slurry.
