A dielectric barrier discharge reactor packed with both Hopcalite & glass beads has been investigated for the total oxidation of toluene adsorbed on Hopcalite. The catalytic activity and selectivity through possible formation by-products during NTP abatement irreversibly have by FT-IR mass spectrometer. regeneration used established (i) determining amount regenerated Hopcalite, (ii) investigati...

Mold powders in continuous casting of steel contain fluorine through mainly CaF2 and occasionally NaF and Na3AlF6. Fluorine develops dangerous gases such as SiF4 and HF at high temperatures. In this study, CaF2 is partly replaced by substances such as Na2CO3, ZnO and Fe2O3.Sulfur free Portland cement clinker containing gypsum was used as a new product base. These additions developed comparable ...

Recovery of manganese from ores was investigated by reductive leaching method using reeds as a reductant in the sulfuric acid medium. Cellulose, hemicellulose, and lignin are natural reducing agents which widely used to recover manganese. Effects calcination temperature holding time on efficiency impurities were examined. The have significant effect extraction experimental results demonstrated ...
