Production of Jet Fuels from Coal Derived Liquids. Volume 6. Preliminary Analysis of Upgrading Alternatives for the Great Plains Liquid By-Production Streams

摘要

Amoco and Lummus Crest have developed seven cases for upgrading by-product liquids from the Great Plains Coal Gasification plant to jet fuels, and in several of the cases, saleable chemicals in addition to jet fuels. The analysis shows that the various grades of jet fuel can be produced from the Great Plains tar oil, but not economically. However the phenolic and naptha streams do have the potential to significantly increase (on the order of $10-15 million/year) the net revenues at Great Plains by producing chemicals, especially cresylic acid, cresol, and xylenol. The amount of these chemicals, which can be marketed, is a concern, but profits can be generated even when oxygenated chemical sales are limited to 10 percent of the U.S. market. Another concern is that while commercial processes exist to extract phenolic mixtures, these processes have not been demonstrated with the Great Plains phenolic stream.
