During the years 1977 through 1984, laboratory and pilot plant evaluations were made at Texaco's Montebello Research Laboratory to determine the suitability of various residual materials from DOE sponsored coal liquefaction projects as feedstocks for the Texaco Gasification Process. Fourteen laboratory evaluations, eight preliminary pilot plant evaluations, four extended pilot plant evaluations and one sustained pilot plant evaluation were completed with coal liquefaction residues from seven different processes. Operating pressures from 350 psig to 1200 psig were demonstrated. Most of the residues may be fed to a Texaco gasifier either as a molten fluid or as a slurry of ground solids in water. Some of the residues, such as the Rocketdyne char and the SRC-1 mineral ash residue from the Kerr McGee solvent deashing process, can be fed to a Texaco gasifier only as a water slurry. The extended and sustained pilot plant evaluations demonstrated that SRC-II and H-Coal liquefaction residues may be efficiently gasified as molten fluids. The extruded form of the SRC-I mineral ash residue from the Kerr McGee solvent deashing process was a suitable feedstock when fed to the gasifier as a water slurry. Exxon EDS residue was difficult to handle in the pilot plant as a molten fluid because of its high viscosity and thermal instability. However, it is a suitable feedstock when fed to the gasifier as a water slurry. The slurry feed system was easier to operate than the molten feed system, however the gasifier operated more efficiently on molten feed. 3 figures, 5 tables.
