Robin, A. M.

A laboratory evaluation of a 20-pound sample of Vacuum Flash Drum Bottoms from the SRC II Plant at Ft. Lewis, Washington was completed. The sample, which was obtained from the liquefaction of Powhatan coal, was judged to be a suitable feedstock for the Texaco Synthesis Gas Generation Process. It can be charged directly to the gasifier at a temperature of about 615/sup 0/F. The material is too viscous to be pumped with the pilot plant equipment, however, which is capable of maintaining a temperature of only 515/sup 0/F. The addition of 3 to 5 percent cutter will be required for the pilot plant tests. No cutter will be required for a commercial plant. Based on these results, operating conditons and yields were estimated for gasifying 1000 pounds per hour of molten undiluted residue at 350 psig. A Type II preliminary pilot plant evaluation is planned.
