Pennsylvania anthracites

The low ratio of hydrogen to oxygen in the anthraxolite (0.534) is similar to that of Pennsylvania anthracites though the latter have, on the average, nearly twice as much of these components. 

The similarity between x-ray diffractograms of Pennsylvania anthracite and the anthraxolite suggests a common metamorphic history rather than a common origin. The dimensions of the carbon crystallites in the anthraxolite have been approximated on the basis of published relationships between crystallite dimensions, carbon contents, and interlayer spacing. These data indicate... 

The apparent specific gravity of the various lithotypes was measured. Results (Table VI) indicate that the order of increasing density for the lithotypes is vitrain, durain, and fusain. For Pennsylvania anthracites, the specific gravity for vitrain was found to vary between 1.36 and 1.53 for durain between 1.43 and 1.73 for fusain between 1.93 and 2.30. 

Emission spectroscopy analyses of the anthracites (Table IX) show that 90% of the ash of Pennsylvania anthracites is composed of silicon, aluminum, and iron-bearing minerals. 

Kinetics of Volatile Matter Release from Pennsylvania Anthracites... 

Philip L. Walker Hardgrove grindability data for many Pennsylvania anthracites have been determined and reported on in the Proceedings of the 1956 Anthracite Conference held at Pennsylvania State University. 

L. L. Newman Dr. Mackowsky has already asked you if you related your studies on the kinetics of volatile matter release from Pennsylvania anthracites to the petrographic constituents of the coal. Can you not say in effect that the coals from the various collieries differ from each other quite significantly with respect to their petrographic composition and that identification of a coal by source may identify it petrographically to some extent How do the results of these studies relate decrepitation actually experienced in industrial operations ... 

Labelled Oxygen Adsorption. When five milliliters of oxygen labelled with a trace of 0-15 were injected onto the Pennsylvania anthracite, about 5% was retained on the column at low temperature. All of this oxygen was desorbed during the heating cycle. When a mixture of labelled O2, CO2 and H2O labelled with 0-15 in proportions of 80 15 5 in 5 cc of nitrogen was injected onto the column with no added carrier (approximately 10 molecules of O2 due to ppm impurities of 0-16, 02), all of the activity was retained on the column. When 1 cc of O2 was added to the mixture only activities which corresponded to CO2 and H2O were retained on the column. When 1 cc of a 50 50 mixture of CO2 and O2 was added only about 5% of the activity was retained on the column. This activity probably corresponds to the water activity.

The EECP project will be located adjacent to an existing power plant owned by WMPI in Gilberton, Pennsylvania. It will process 4,700 tons per day of eastern Pennsylvania anthracite coal waste (culm) to produce 3,732 barrels per day (b/d) of upgraded CTE diesel, 1,281 b/d of stabilized CTE naphtha, and 39 MW of electric power for export. Other products will include steam and sulfur. The gross plant efficiency is estimated to be 45% (5). A schematic flow diagram of the EECP is shown in Figure 2.

All of the anthracites used in this investigation were from Pennsylvania except two, a Russian anthracite and a Welsh anthracite. Tables I and II indicate the various designations and sources of the anthracite and lithotype samples.

At the end of the settling period, the suspended solids were decanted, and the settled solids were recovered. Each fraction was placed in an evaporating dish, oven dried and weighed. Selective flocculation of coal mixtures with pyrite was made on suspensions containing equal proportions of coal and pyrite, using 200 mg/l PAAX dispersant at pH 10. The flocculation procedure was the same as described above, except that the products were qualitatively analyzed by visual inspection of both fractions. The coal samples used in these experiments were anthracite coal, supplied by Wilkes-Barre, Pennsylvania, and the pyrite used was pure crystals from Wards Natural Sciences, Inc., Rochester, N.Y. 

Curve 4 of Fig. 1 shows the scattered intensity for Pennsylvania Buck Mountain anthracite (PSOC 081). Quite similar scattering curves were recorded for some other anthracites. 

Bituminous and sub-bituminous coals account for the major share of all coal produced in the United States. In 2000, production of all types of coal totaled almost 1.1 billion short tons, of which about 95 percent was bituminous or sub-bituminous (Fig. 19.1). Despite its clean burning characteristics, anthracite, most of which is mined in northeastern Pennsylvania, accounts for a diminishing share of total coal production. Figure 19.2 presents data on coal consumption in the United States.
