About 2 1/4 tons of vacuum tower bottoms from the Exxon Donor Solvent Process from the liquefaction of Illinois No. 6 coal were successfully gasified in a 1/2 ton per hour pilot plant at Texaco's Montebello Research Laboratory. The single five hour run was completed at 24 atmospheres pressure. A 99 percent conversion of the carbon in the feed to syngas was achieved yielding 37.1 SCF of dry syngas per pound of residue charged. The dry syngas contained about 90 (vol) percent carbon monoxide plus hydrogen. The melt point range and viscosity of the residue were so high that it was difficult to handle this material in the pilot plant equipment. The short pilot plant run did confirm the operability of the Texaco Coal Gasification Process with this feedstock, and the data obtained confirm earlier predictions of performance efficiency.
