Due to their chemical and thermal stability, electrical conductivity, and high specific surface
areas, nanocarbons and porous carbon materials have found use in numerous key …

The effects of different atmospheres on the distribution of organic and inorganic sulphur
compounds during high-pyrite coal pyrolysis were investigated. Sulphur compound releases …

In this study, two Chinese coals, Jiexiu (JX) and Yanzhou (YZ) raw coals, their deashed
coals and depyrited coals, were used to investigate the effects of CO 2 on sulfur removal and …

High sulfur coal sample from C1 seam in Tabas mine (Iran) was studied. The effect of
microwave pre-irradiation followed by a peroxyacetic acid (PAA) desulfurization on sulfur …

A comparative study of the effect of microwave irradiation on the determination of organic
sulfur forms in high sulfur coal samples of Tabas coal was studied by atmospheric pressure …

Atmospheric pressure-temperature programmed reduction (AP-TPR) and X-ray
photoelectron spectroscopy (XPS) techniques were applied to low rank coals sulphur study …

Two Bulgarian high sulphur coals, ie subbutiminious (Pirin) and lignite (Maritza East), and
one Turkish lignite (Cayirhan-Beypazari) are biodesulphurized on laboratory scale. Prior to …

Oil shale samples were retorted in a quartz tube reactor to determine the effect of the
retorting temperature on the product yield and release characteristics of gases and shale oil …

The selective heating of pyrite (FeS 2) in coal by microwave makes its removal more
efficient, but the gas produced by high-sulfur coal during microwave irradiation may affect …

Chinese Yima coal and its HCl/HF and HCl/HF/HNO3 treated samples were pyrolyzed in a
fixed bed reactor under a pressure of 2 MPa. The effect of mineral on organic and pyrite …
