Appalachian Coal Ash Richest in Rare Earth Elements
Appalachian Coal Ash Rare Earth Elements
2016/6/12
A study of the content of rare earth elements in U.S. coal ashes shows that coal mined from the Appalachian Mountains could be the proverbial golden goose for hard-to-find materials critical to clean ...
Qualitative and quantitative ATR-FTIR analysis and its application to coal char of different ranks
qualitative quantitative FT-IR coal char
2015/3/11
This paper analyzes the coal to char stages of char formation of six coals of different ranks by using Fourier transform infrared coupled with attenuated total reflectance (ATR-FTIR). The chars were o...
Transformation of chlorine in NaCl-loaded Victorian brown coal during the gasification in steam
chlorine gasification volatile-char interactions XANES
2014/4/28
This study is to examine the changes in Cl volatilizations and chemical forms in NaCl-loaded Victorian brown coal during gasification in steam at 800 ℃ using Cl K-edge X-ray absorption near-edge struc...
Co-liquefaction of Enriched Coal Maceral Constituents and Sawdust
co-liquefaction coal vitrinite
2009/11/16
Co-liquefaction of coal and sawdust was studied in the presence of hydrogen-donor solvent, tetralin. Coal samples were prepared through floatation of the Xinwen coal, followed by enrichment of maceral...
Coal in the Commonwealth study: points to the future of coal in Australia
Coal the Commonwealth study Australia
2009/11/3
Continued robust use of coal and broad deployment of clean coal technologies is crucial for Australia's energy and economic future, according to a multi-disciplinary study released today by The Univer...
Combustion and air gasification of mechanically activated micro-ground coals in the flux have been studied. Influence of mechanically activated methods at coals grinding on their chemical activeness a...
A STUDY ON SPONTANEOUS IGNITION OF BITUMINOUS COAL
self-heating spontaneous ignition bituminous coals
2009/10/14
The thermal properties of four bituminous coals were studied using isothermal and temperature-programmed calorimeters, such as a differential thermal analysis, a heat flux calorimeter C80 and an therm...
OPTIMISATION OF PULVERISED COAL COMBUSTION BY MEANS OF CFD/CTA MODELLING
CFD modelling pulverised coal-fired boiler thermal radiation
2009/10/13
The objective of the work presented in this paper was to apply a method for handling two-phase reacting flow for prediction of pulverised coal combustion in large-scale boiler furnace and to assess th...
THE '3R' ANTHRACITE CLEAN COAL TECHNOLOGY: ECONOMICAL CONVERSION OF BROWNCOAL TO ANTHRACITE TYPE CLEAN COAL BY LOW TEMPERATURE CARBONIZATION PRE-TREATMENT PROCESS
clean coal carbonization anthracite thermolysis
2009/10/13
The preventive pre-treatment of low grade solid fuels is safer, faster, better and less costly versus the "end-of-the-pipe" post treatment solutions. The "3R" Recycle-Reduce-Reuse integrated environme...
