Obtaining Carbon materials from rubber crumb

Abstract In the paper, obtaining carbon materials from crumb rubber are presented. The process were carried out at 300-400°C by thermal processing (carbonization) method under the inert gas. During carbonization, the percentage of weight loss of samples and their surface area were determined. During the carbonization of rubber crumbs at a temperature of 300 °C from the first 14.82 g of carbon material was obtained and the weight change was 25.9 %. According to increase temperature, the products were decreased. As well as at the temprature 390 °C, the product mass droped to 9.84g and mass changing increased to 51.8%. The result of the electron microscopic analysis of rubber crumb from worn automobile tires, shows that it has heteros tructures with only very small pores. It is established that the spectrum of carbon materials obtained by carbonization with IR spectroscopy has functional groups according to activated carbon's functional groups. The specific surfacearea of the carbon material obtained by carbonization at 300 °C was 2.096 m2/g. At a temperature of 350 °C reaches a maximum value (5,409 m2/g). It shows that the effective carbonization temperature of rubber crumbs is 350 °C.
