The largest volume of coal mined in the USA comes from the Powder River Basin (PRB) located in Wyoming and Montana (EIA 1995). Combustion of the PRB coal produces a high-Ca Class-C fly ash (22-32 wt% CaO) that is widely used as a replacement for Portland cement in concrete. An XRD pattern of this...

The present paper presents batch autoclave data on the direct hydrocracking of a single sub-bituminous coal from the Powder River basin of southeastern Montana. Comparative data were also obtained with the Pittsburgh Seam bituminous coal that was used in the previous work (I). Data on the regeneration of simulated spent melts from such an operation are also given in a continuous bench-scale, fluidized-bed combustion unit.

In order to determine the origin of sulfur in coals, Hackley and Anderson (18) studied the sulfur isotopic composition of various coals from the western United States. Coals from the Powder River Basin, Wyoming were found to have anomalously low values (-18.7 to 3.9 parts per mil). The unusual values of these coals suggest that original plant material and isotopically light secondary sulfur from bacterial activity were the major contributors to the sulfur content of these coals. 

The Hanna Basin coals from Wyoming had higher 63ife values than coals from the Powder River Basin. The pattern of sulfur isotopic composition found in coals from the Hanna Basin revealed that coals near the top of the coal seam contained more of the heavy sulfur isotope than coals stratigraphically lower in the coal seam. The sulfur isotope pattern observed in the Hanna Basin coals suggests that sulfur was introduced in sulfate-rich water from the top of the coal seam.

The oldest and most common application of size enlargement by agglomeration for solid fuels, which now also include biomass [B.25, B.48] (Section 8.2), utilizes different forms of pressure agglomeration. More modem uses of the technology try to convert abundantly available cheap sub-bituminous coal from, for example, the Powder River Basin in Wyoming, USA, into an improved product with increased heating value [6.10.2] (Section 6.10.2).
