Abstract

The main emphasis of this study is the production of black shoe polish using carbon black from waste car tyre. Waste car tyre was pyrolysed in a hot muffle furnace made up of stainless steel in a temperature range of 450-600oC at a heating rate of 20oC/min with size range of 2-4cm long. The maximum carbon black yield was obtained at lower temperature of 450oC, due to the incomplete devolatilization of used tyre. The obtained pyrolytic carbon black residues were studied to investigate their characteristics such as ash content ,moisture content, bulk density, pore volume, porosity, TGA, SEM, BET and FTIR. Characterizations were used to investigate the features of pyrolyzed carbon black. It was treated with acid for demineralization. Adsorption capacities for methylene blue by raw and acid treated carbon black were compared, and the results showed that the acid treated carbon black had the highest adsorption capacity. Thermogravimetric analysis was used to determine the kinetic behavior of the waste car tyre carbon black and standard carbon black and the effect of heating rate on the mass loss of waste car tyre, SEM image indicated that carbon black has variety of pores. Surface area on produced carbon black and demineralized carbon black were compared and the results show that the demineralized carbon black had the larger surface area than the produced carbon black. FTIR was used to observed the functional groups of the carbon black and finally black shoe polish was manufactured
