Abstract

Catalytic cracking is a promising approach to realize the resource utilization of waste tires. Herein, a new composite catalyst, nano-ZSM-5/MgAl-LDO, is synthesized, and catalytic cracking of waste tires over the composite catalyst is explored. Experimental results indicate that nano-ZSM-5/MgAl-LDO composite catalyst is characterized by high dispersion of nano-ZSM-5 on the surface of LDO, large Brunauer–Emmett–Teller-specific surface area, large pore diameter and volume, and suitable acid and basic properties. Moreover, not only does the nano-ZSM-5/MgAl-LDO composite catalyst increase the conversion rate (62.04%) and degradation rate (1.33 × 10⁻³ s⁻¹) of waste tires, but it also enhances the selectivity (33.32%) of light hydrocarbons in pyrolysis products, which was nearly 10% higher than that of thermal pyrolysis.
