Most of the Paleogene coal mined in the Powder River Basin today has less than one percent sulfur, which makes it the lowest sulfur coal mined in the United States. Moisture is also an important parameter in Wyoming coal.

The Powder River Basin (PRB), located in the western United States, is a coal mining region that has evolved throughout the half century since the first largescale mine began in the 1970s, as shown in Fig. related to commodity pricing, high inflationary periods and, more recently, low demand, associated with power producers switching from coal to natural gas or renewable energy ...

The objective of this research is to develop a costeffective catalytic pyrolysis process for producing highquality oil and gas from coal with low CO 2 emission. Catalytic pyrolysis of the Powder River Basin coal using composite Na 2 CO 3FeCO 3 catalysts has been investigated in a fixed bed reactor between 500 and 800 °C under atmospheric pressure to evaluate effects of catalyst on quantity ...

The Powder River Basin (PRB) of Wyoming and Montana, USA, is a prime candidate to investigate the feasibility of extracting REE/CM from coal and associated sediments. The more » PRB hosts thick (>50 ft) coal seams that are mined at the surface and more than 40% of the coal produced in the US comes from the PRB.

COAL QUALITY Connor (1989) reported that the Mammoth coal in the Bull Mountain Basin ranges in apparent rank from subbituminous A to high volatile bituminous C coal. Details of Mammoth coal quality are available in Connor (1989). Pontolillo and Stanton (1994) analyzed two samples from the basin.

The estimate assumed that Powder River Basin coal generates 8,500 BTUs per pound, and that one million BTUs would produce pounds of CO2, consistent with Department of Energy figures. The final calculation was 199 million tons of CO2 per year in "direct" emissions from the coal exports.
