West Virginia coal

Three West Virginia coals were supplied by the West Virgmia Geological Survey (WVGS). The particular coals were chosen on the basis of rank, petrographic composition, and mineral matter content The coals were limited to the bituminous rank since these coals are the most amenable to the NMP solvent extraction process and are mdigenous to the Appalachian region. Some of the coal characteristics are listed in Table 2. [Pg.212]

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). [Pg.82]

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. [Pg.121]

Some work has been reported utilizing alcohols for supercritical extraction of coal. Makabe et al.(5) reported extraction of coal with ethanol-sodium hydroxide mixtures with the objective of maximizing extraction yield no sulfur data were reported. Methyl alcohol reaction with a low volatile bituminous West Virginia coal at higher temperatures (460-600 °C) was reported by Garner et al.(J>). Promotion of coal gasification was the objective of that study sulfur content of the resultant char was not reported. [Pg.83]

Heavy oils derived from petroleum were separated by using the method developed by the USBM-API (5) Project 60 and analyzed by means of mass spectroscopy. The procedure used for separation and characterization of petroleum heavy oil was adopted to study heavy oil from coal liquids derived from Char-Oil-Energy-Development (COED) Syncrude from Utah coal (6) and western Kentucky coal (7) and Synthoil from West Virginia coal (i, 8). [Pg.258]

Treatment of many materials results in the liberation of the trace elements into the environment, which can have an impact on health. Coal is a particularly useful example of a major source of trace elements poured into the environment from coal combustion. Coal contains an alphabet soup of trace elements, including arsenic, mercury, uranium, selenium, and chromium. Pyrite is a ubiquitous mineral found in coal, but coal can also contain a variety of other mineral phases. West Virginia coal, for example, includes clay minerals such as kaolinite (35%) and illite (35%i), quartz (18%i), pyrite (7%), and calcite (3%). A number of projects that utilize coal for power generation while minimizing the impact on the environment have been described. An excellent example is the SNOX (trademark owner Haldor Topsoe) demonstration project, which utilizes high-sulfur coal (2.8%). The demonstration project of this technology, equally funded by the U.S. Department of Energy and participants at a total cost... [Pg.3129]

Slags were prepared by mixing preweighed amounts of additives and coal ash. The coal ash was obtained from Bituminous Coal Research, Inc. It was prepared by ashing Loveridge Seam, West Virginia coal in air at 750°C, followed by a reduction in a 60%CO-40%C02 gas at 1000°C, then cooled under nitrogen. [Pg.174]

Analyses of the coals tested are given in Table II. Most of the tests were conducted with the 1.6-percent-sulfur Pittsburgh seam coal. Twelve tests were carried out with the 3.1-percent-sulfur West Virginia coal. [This also is a Pittsburgh seam coal, but is referred to as "West Virginia coal" (from Marion County, West Virginia) to facilitate discussion.] Two tests were conducted with the 1.0-percent-sulfur Kentucky coal. [Pg.356]

Kentucky Coal (1.0 Percent Sulfur) and West Virginia Coal (3.1 Percent Sulfur). Two tests were conducted with a Kentucky coal containing 1.0 percent sulfur, and six tests were conducted with a West Virginia coal containing 3.1 percent sulfur. Bag-house temperature was maintained at 400-420°F, and the cycle times were either 15 or 30 minutes. [Pg.362]

The solvent-refined coal heavy distillate (SRC II HD, bp 260-450 °C) that was analyzed and used in this study was collected during the processing of a West Virginia coal from the Pittsburgh seam. Data from the analysis of a solvent-refined coal vacuum residue (SRC II VR) from the same process was also used. A coal tar was obtained from the National Bureau of Standards. This tar was a medium crude coke-oven tar... [Pg.240]

The causes of structure fires resulting in civilian deaths and injuries indicate that other equipment caused 31 percent of the civilian deaths and 49 percent of the civilian injuries. As a point of historical reference, the deadliest U.S. fire or explosion on record in the industrial or manufacturing property class was the 1907 Monongha, West Virginia, coal-mine explosion that claimed 361 lives. [Pg.332]

The scope of each is indicated in the analyses of a West Virginia coal (Table 6.2) in which the ultimate analysis has been converted to the as-received basis. The analysis on the as-received basis includes the total moisture content of the coal received at the plant. Similarly, the as-fired basis includes the total moisture content of the coal as it enters the boiler furnace or pulverizer. Standard laboratory procedures for making these analyses appear in ASTM D 271, Sampling Analysis, Laboratory, Coal Coke. ... [Pg.897]

Finally, I want to thank my wife, Natasha, for her interest and support throughout this project. She was a member of Ken Martis s field trip to the West Virginia coal fields where she witnessed Appalachian megaengineering impacts firsthand, she faithfully attended the conference in 2008, and survived the fall 2007 Fulbright experience in Semipalatinsk, Kazakhstan. I am very grateful for her affection and constant companionship. [Pg.2278]
