Abstract

The increase in waste and used tires has become a serious problem in environmental pollution. As vehicles increase and the average mileage of each vehicle increases, this pollution increases every day. Having a significant amount of thermal energy in tires has made their recycling very attractive to solve environmental problems, so that the recycling of waste tires not only has no harmful effects on the environment, but also the source of industrial development and economic profitability and processing and production of other products. In this research, the aim of this study is to investigate the two-stage heat-catalytic pyrolysis process of waste tires on ZSM-5, Y and β zeolite catalysts in order to produce quality of liquid fuel. The properties of the catalysts were evaluated using X-ray diffraction (XRD) spectroscopy, scanning electron microscopy (SEM) and nitrogen adsorption-desorption analysis. The performance of commercial catalysts in the catalytic cracking of liquid product resulting from thermal pyrolysis of waste tires in the presence of nitrogen gas was investigated. The results showed that zeolite Y with liquid yield of 78.91% by weight had better performance in the above process than the other two catalysts.
