Reduction of Sulfur and Ash from Tabas Coal by Froth Flotation [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2007 Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high

A global platform for accelerating coal efficiency (PACE) [PDF]
The World Coal Association released this concept paper in December 2014 on establishing a Platform for Accelerating Coal Efficiency (PACE). The vision of PACE would be that for countries choosing to use coal, the most efficient power plant ...

Combustion of coal gas fuels in a staged combustor [PDF]
, 1982 Gaseous fuels produced from coal resources generally have heating values much lower than natural gas; the low heating value could result in unstable or inefficient combustion. Coal gas fuels may contain ammonia which if oxidized in an uncontrolled manner

Mechanism‐Guided Thermoelectric Strategies for Smart Fire Prevention
Advanced Materials, EarlyView.This review highlights recent advances in thermoelectric materials for smart fire prevention and early warning. Mechanism‐guided strategies—such as structural design, energy filtering, ion doping, and ionic thermoelectric effects—are systematically discussed, offering insights into the development of self‐powered, high‐sensitivity fire warning systems ...

A novel dry coal feeding concept for high-pressure gasifiers [PDF]
, 1977 A novel dry coal feeding concept was developed for injecting ground coal into high-pressure gasifiers. Significant power savings are projected because the coal is injected directly with a ram and there is no requirement for pumping large volumes of gas ...

Advanced Materials Interfaces, EarlyView.The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Water absorption and salt attack resistance of coal ash brick made of different percentage of foam content [PDF]
, 2014 Coal ash which constitute of fly ash and bottom ash were proved to be used as main component in brick production. However, published work on the coal ash brick with addition of foam in order to produce lightweight brick is still lacking. This thesis

Advanced Materials Technologies, EarlyView.Graphene is grown from pyrene and its carboxylated derivative, 1‐pyrenecarboxylic acid (1‐PCA). The carboxylic acid group of 1‐PCA underwent decarboxylation to produce pyrene and CO2, thereby triggering the Boudouard reaction. This reaction results in graphene with high charge‐carrier mobility by decreasing vacancy‐type defects and oxygen groups in the
