Book excerpt: Our current operating hypothesis is that coal consists of a cross linked macromolecular network of high aromatic clusters held together by linkages which include ethers and methylene groups. These clusters are arranged like beads on a string with 3 to 5 beads between branch points. Coal can be liqufied most readily by cleaving the links between the clusters. Doing chemistry on the clusters in the whole coal is very difficult because of the problems of getting to the clusters by reagents. It is fortunate that the linkages between clusters are quite reactive. But even with this, it is clear that coal liquefaction is a formidable chemical problem. There is much wisdom is Sternberg's suggestion that the chemistry of the freed clusters (pre-asphaltenes) be developed. Our model indicates that the chemistry which results in freeing the clusters from the network also should be explored and broadened.

Available in PDF, EPUB and Kindle. Book excerpt: In the lifetimes of the authors, the world and especially the United States have received three significant “wake-up calls” on energy production and consumption. The first of these occurred on October 15, 1973 when the Yom Kippur War began with an attack by Syria and Egypt on Israel. The United States and many western countries supported Israel. Because of the western support of Israel, several Arab oil exporting nations imposed an oil embargo on the west. These nations withheld five million barrels of oil per day. Other countries made up about one million barrels of oil per day but the net loss of four million barrels of oil production per day extended through March of 1974. This represented 7% of the free world’s (i. e. , excluding the USSR) oil production. In 1972 the price of crude oil was about $3. 00 per barrel and by the end of 1974 the price of oil had risen by a factor of 4 to over $12. 00. This resulted in one of the worst recessions in the post World War II era. As a result, there was a movement in the United States to become energy independent. At that time the United States imported about one third of its oil (about five million barrels per day). After the embargo was lifted, the world chose to ignore the “wake-up call” and went on with business as usual.

This book was released on 2017-02-03 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Structure in Paleozoic Bituminous Coals Views and conceptions of the origin, composition, and general na ture of coal differ so widely that to determine the real extent of actual knowledge is no easy matter. The chemist finds difficulty in attacking the chemical problems and the engineer lacks a broad chemical basis for the study of his problems. Thus the economical and efficient utilization of coal in the industries suffers froma lack of knowledge of the composition of coal itself. Most scientists interested in this matter, as has been brought out in discussions during the recent investigation of coal problems, appear to have only a vague idea of the components of coal and their origin. Some are even in doubt as to whether substances derived from the wood and resins of plants form a part of coal; and few seem to have more than' the dimmest idea of what are the components of coal, the condition in which these now exist, and the transformations that they have undergone.
