A laboratory evaluation of a 20-pound sample of vacuum tower bottoms from the Exxon Donor solvent (EDS) liquefaction process was completed at Texaco's Montebello Research Laboratory. The sample was obtained during the liquefaction of Texas lignite from the Martin Lake mine at the EDS liquefaction process pilot plant in Baytown, Texas. The residue is judged to be suitable feedstock for the Texaco Gasification Process charged as an aqueous slurry of pulverized solid at ambient temperature. Feeding the residue as a molten fluid would require that it be stored and fed to the gasifier at temperatures in excess of 600/sup 0/F. It is thus judged to be a marginally acceptable feedstock for the Texaco Gasification Process as a molten fluid. Based on the laboratory tests, operating conditions and yields were estimated for gasifying 1600 pounds per hour of solid residue in a water slurry and for gasifying 1000 pounds per hour of molten residue, both at a gasifier pressure of 1000 psig.
