The following study demonstrates the possibility of producing different activated carbons from a mixture of waste tires and tubes. The mixture was pyrolyzed at different temperatures namely (400,450 and 500 о C) for two hours for the determination of best condition of heating. It was found through the study that semi carbonized marital produced via pyrolyis at 500 о C was the best; thus it was ...

The adsorption of hydrogen on carbon nanotubes and activated carbons has generated considerable interest in relation to hydrogen storage for fuel cells applications[1-3]. However, the widespread use of hydrogen as a fuel is limited by the lack of a convenient and cost-effective method of hydrogen storage. Adsorption of supercritical hydrogen is limited by the low interaction energy between hydr...

Twelve well-characterized activated carbons with average micropore widths between 0.7 and 2 nm, total surface areas of 378–1270 m2 g−1 and specific capacitances C up to 320 F g−1 have been investigated, using H2SO4 2 M as electrolyte. Some of the carbons have also been oxidized with (NH4)2S2O8, which leads to specific oxygen contents between 0.4 and 7.1 mol m−2 of carbon surface area. It appear...
