Existing technology transfer report. Liquefaction process and product studies

Technical Report ·
OSTI ID:6379147

Summaries of 4 internally funded research projects on coal liquefaction process studies performed at Air Products and Chemicals, Inc. between 1974 and 1980 are presented, and the production of carbon products from SRC are discussed. The effects of soluble and slurry catalysts on coal liquefaction yields and hydrogen consumption were examined. The coal process development unit was modified to permit coal slurries to be processed. A program was written to allow raw experimental data to be interactively entered into data files. The selectiveness and effectiveness of acid and caustic washing for removal of nitrogen compounds and phenols from SRC-I naphtha and middle distillates were determined quantitatively. Coal grinding methods were examined. Because of its condensed polyaromatic structure, coal has a much lower hydrogen-to-carbon (H/C) ratio than liquid petroleum-derived fuels. The economics of the SRC-I coal liquefaction process are improved by focusing on products having a low H/C ratio, so that the processing cost is minimized. Specialty carbon products are a very inviting market since they have very low H/C ratios, sell at premium prices, and are generally produced from petroleum. The products investigated included: anode coke and binder pitch for the aluminum industry; binder pitch for metallurgical coke; asphalt feedstock; carbon black; and Bergbau SRC/polymer blend product. An extensive bibliography is included.
