THE INFLUENCE OF NONTRADITIONAL METHODS OF PRETREATING WASTE TIRE FOR THE CATALYTIC HYDROGENATION PROCESSING

Nontraditional methods of pretreating waste tires such as radiation exposure and processing with liquid nitrogen were investigated for the aim of influencing to the yield of liquid products of the catalytic hydrogenation. Treatment waste tire with liquid nitrogen gave possibility to the mechanical separation of the polymer mass from the tire cord and were divided into particle size types: 0.4-0.6, 0.8-1.0, 8.0-10.0 mm respectively. The 0.4-0.6 mm particle size of tire had given a high yield of liquid product in catalytic thermal processing. After, the tire crumbs with particle size 0.4-0.6 mm was subjected under dose of radiation exposure in the ranged of 100-500 kGy. At a dose of 300 kGy was observed the highest yield of liquid product.
