Experimental Study of Hydrogasification of Lignite and Subbituminous Coal Chars
The experimental facility for pressure hydrogasification research was adapted to the pressure of 10 MPa and temperature of 1300 K, which ensured repeatability of results and hydrogen heating to the process temperature. A hydrogasification reaction of chars produced from two rank coals was investigated at temperatures up to 1173 K, pressures up to 8 MPa, and the gas flow rates of 0.5-5 dm(n)(3)/...
متن کاملEffect of Pulp Density on Biodesulfurization of Mongolian Lignite Coal
Biological processes based on oxidation of sulfur compounds by chemolithotrophic microorganisms are emerging as an efficient and eco-friendly technique for removal of sulfur from the coal. In the present article, study was carried out to investigate the potential of biodesulfurization process in removing the sulfur from lignite coal sample collected from a Mongolian coal mine. The batch biodesu...
متن کاملRare Earth Elements in Soils of Jharia Coal Field
There are many sources trough which the soil get enriched and contaminated with REEs. The determination of REEs in environmental samples has been limited because of the lack of sensitive analytical techniques. Soil samples were collected from four sites including open cast coal mine, natural coal burning, coal washery and control in the coal field located in Dhanbad, India. Total concentrations...
متن کاملCoal fly ash as a resource for rare earth elements
Rare earth elements (REE) have been recognised as critical raw materials, crucial for many clean technologies. As the gap between their global demand and supply increases, the search for their alternative resources becomes more and more important, especially for the countries which depend highly on their import. Coal fly ash (CFA), which when not utilised is considered waste, has been regarded ...
متن کاملThe Pyrolysis Behavior of Victorian Lignite at Elevated Pressures: Contrast to Bituminous Coal
Victorian lignites (brown coals) in Australia have long been the mainstay of the Victorian economy, providing low-cost electricity to the state. In order to secure energy supplies for the future and to reduce the environmental impacts of power generation using the lignites, the Cooperative Research Centre (CRC) for Clean Power from Lignite is developing an Advanced Pressurized Fluidized-Bed Com...
