Major work on zinc chloride catalysts for hydrogenation and hydrocracking of coal has been carried out by Zielke, Gorin, Struck and coworers at Consolidation Coal (now Conoco Coal Development Co.) (1). The emphasis there has been on a full boiling-point range of liquid product, from treatment at temperatures between 385 and 425°C and hydrogen pressures of 140 to 200 bars. 

CSF [Consol Synthetic Fuels] A two-stage coal liquifaction process. In the first stage, the coal is extracted with process-derived oil and the ash removed. In the second, the extract is catalytically hydrogenated. Piloted by the Consolidation Coal Company, Cresap, WV, from 1963 to 1972. See also H-Coal, SRC, Synthoil.

Despite considerable effort to understand the chemical nature of the organic and inorganic portions of coal, and substantial advances in instrumentation and methodologies, much of coal s chemical nature remains intractable. This paper reviews methods and their limitations for the determination of specific minerals in coal, and presents results of efforts at Consolidation Coal Company to develop FTIR methods for routine coal mineralogy. 

The authors wish to thank the Coal Research Board, Commonwealth of Pennsylvania, the American Oil Co. and Consolidation Coal Co. for their support. Special thanks are due to the management of the Research Division of Consolidation Coal Co. for permitting the use of the facilities in their radiological laboratory. The spectra were recorded at Spectra Research Laboratories, Altadena, Calif, by David Lawson, whose kind cooperation is gratefully acknowledged. 

Lignite Coal. A brownish-black coal that is intermediate in coalihcalion between peat and sub-bituminous coal consolidated coal with a calorific value less than 8,300 Btu per pound (4615 Calories/kg), on a moist, mincial-matter-free basis. Synonyms include brown lignite and brown coat. Further classifications of lignite are made on the basis of calorific value ...

The Pittsburg and Midway Coal Mining Company provided the SRC-II process products that were used as feeds in these studies. They were produced in the Fort Lewis, Washington, pilot plant from a West Virginia coal (Pittsburg Seam, Blacksville No. 2 Mine of the Consolidated Coal Company). 

H-Coal naphthas and distillates derived from Illinois No. 6 (Burning Star Mine) and Wyodak coals were supplied by Hydrocarbon Research, Inc. The naphthas and distillates were blended in the appropriate proportions to obtain a whole syncrude derived from each coal. Properties of these syncrudes are shown in Table I. For comparison, Table I also shows properties of the SRC-II syncrude used in the study described in the previous chapter. The SRC-II syncrude was derived from a West Virginia coal (Pittsburgh Seam, Blacksville No. 2 Mine of the consolidated Coal Company). The H-Coal and SRC-II syncrudes are not directly comparable because the coals used to derive these syncrudes differ. 

We thank Simon C. Brassell of Stanford University, Ed L. Obermiller of Consolidation Coal Company, and Otto P. Strausz of the University of Alberta for serving on the organizing committee for the symposium and as advisers during the preparation of this volume. 

Finally, financial support that made it possible for many foreign speakers to participate in the symposium is most gratefiilly acknowledged. Substantial contributions were made by the following Amoco Production Company, Arco Oil and Gas Company, Conoco Inc., Consolidation Coal Company, Mobil Research and Development Corporation, Unocal Corporation, and the American Chemical Society Petroleum Research Fund. 

In the case of the Consolidation coal, a few data were obtained at different temperatures. Figure 5 shows the result of plotting the data as a second order rate process at temperatures...

The Pittsburgh Seam (No. 8) Bituminous coal is from the Ireland Mine of the Consolidation Coal Company. 

Much work has been reported on the destruction of caking properties of coal. Low temperature carbonization, if carried far enough, drives off enough volatile matter so that the remaining char does not agglomerate. Examples of this are Consolidation Coal Co/s Montour char used in much of the early hydrogasification work, and the more recent char... 

Particles from a run in which untreated coal was fed were also examined. This coal was from Pittsburgh No. 8 seam but from a different mine—Consolidation Coal Co/s Montour 4 mine. The hydrogasification reaction was conducted entirely in 18 feet of free fall. The run could not be completed because of gradual caking of coal in the feed tube and in the reactor. However, the structure of the residue that was obtained is of interest (Figure 4). It is much more uniform in appearance and reflectance than residues from runs with pretreated coal. Almost all of the particles have a degenerate foam structure—i.e., they are filled with...

This reaction is the basis of Consolidation Coal Co/s carbon dioxide acceptor gasification process (13,17,18), which eliminates need for oxygen to provide heat to the steam-carbon reaction. The process could be modified for recovering elemental sulfur by incorporating a step using Reaction 1.
