Simultaneous thermogravimetry-mass spectrometry studies of a pyrolytic decomposition of mixtures of different plastic wastes/coking coal were carried out. The investigation was performed at temperatures up to 1000oC in a helium atmosphere under dynamic conditions at a heating rate of 25 oC/min. Five thermoplastics, commonly found in municipal wastes: low density polyethylene (LDPE), high densit...

Coal based thermal power generation accounts for 44.7% of the world's electricity and coal alone provides about 80% of the total energy demand in India. Energy-intensive industries deteriorate the air quality of the residential areas due to release of different pollutants, especially a range of deleterious heavy metals like Hg, Cd, Cu, Pb, and Cr. Near about 53.3 percent of the coal produced ev...

An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on 0.5mm coal fines using flotation and oleo flotation by splitting at size 0.063mm.Size fraction of 0.5mm-0.063mm and -0.063mm size were treated in flotation and Oleo flotation respectively. The washability studies ...

Hydrocarhon free radicals play a very important role in many thermalchemistry processes. including combustion. petroleum and coal coking, coal liquefaction and pyrolysis. oil shale retorting, thermal stability of fuels as well as free rddiciij polymerization. To obtain heats of formation (AH",) of the radicals is very essential for the fundamental understanding of thermal chemistry and mechanis...
