Gasification of residual materials from coal liquefaction. Quarterly report, July--September 1977
A total of seven type I Laboratory Evaluations and one type II Preliminary Pilot Plant Evaluation have been completed to date. A final report on the type II Preliminary Pilot Plant Evaluation of 20 bbls of H-Coal Syncrude Vacuum Tower Bottoms was completed and submitted to ERDA for approval. Pertinent results are summarized. Two 5-gallon samples were received: The first is a sample of vacuum flash drum bottoms from the SRC II coal liquefaction pilot plant in Tacoma, Washington, and the second is a sample of vacuum tower bottoms from the Exxon Donor Solvent coal liquefaction process. Type I Laboratory Evaluations have been completed and reports have been written. The expected yields and operating conditions based on the laboratory evaluation of the SRC II vacuum drum bottoms are summarized. The sample, which was obtained from the liquefaction of Kentucky No. 9 and 14 coal, was judged to be a suitable feedstock for the Texaco Coal Gasification Process. It may be charged directly to a Texaco gasifier as a molten fluid at 700/sup 0/F. The material is too viscous to be pumped with the pilot plant equipment available, however. If pilot plant tests are desired, a suitable cutter stock must be added to reduce the viscosity to an acceptable level. The expected yields and operating conditions based on the laboratory evaluation of the Exxon vacuum tower bottoms are summarized. The sample, which was obtained from the liquefaction of Illinois No. 6 coal, was judged to be a suitable feedstock for the Texaco Coal Gasification Process. It may be charged directly to a Texaco gasifier as a molten fluid at 700/sup 0/F. The material is too viscous to be pumped with the pilot plant equipment available, and, therefore, will require the addition of a cutter to reduce its viscosity.
