Frontiers Catalytic Pyrolysis of Plastic Waste: Moving Toward
Pyrolysis is a common technique used to convert plastic waste into energy, in the form of solid, liquid and gaseous fuels. Pyrolysis is the thermal degradation of plastic waste at different temperatures (300–900°C), in the absence of oxygen, to produced liquid oil ( Rehan et al., 2017 ). Catalytic cracking of polyethylene plastic waste using Therefore, this has led us to explore the catalytic pyrolysis of plastic waste using zeolite Y synthesized from kaolin deposit in Covenant University, Sango Ota, Ogun state of Nigeria. A stainless steel packed bed reactor was used in the cracking of low-density polyethylene (LDPE) plastic wastes into liquid fuel components at a temperature of 300 ℃ using zeolite Y catalyst.
