Comparative Analysis of Catalytic Cracking and Hydrocracking of Waste Plastic

Abstract

Waste materials from various processes comprising of polyethylene and polystyrene were analyzed for the production of fuel using catalytic cracking and hydrocracking in an autoclave reactor. The composite catalyst USY/SBA‐16 was synthesized in the lab to be employed in the catalytic process because of its outstanding stability and regenerative capability. Each of the two processes produced a fuel with different quality and quantity. Catalytic cracking and hydrocracking of polystyrene and polyethylene were investigated at different temperatures by varying the percentage amount of catalyst and it was found that polystyrene yielded a fuel of better quality as compared to polyethylene.

Performance evaluation and conservation of waste solid plastics into alternative fuel for a pollution‐free environment

“…The quality of pyrolysis is dependent on the selection of waste plastic, feed rate, volume to feed, temperature, reactor capacity, and catalyst type (Anandaram et al., 2022; Panda & Singh, 2011; Park et al., 2002; Sudhagar et al., 2022). The waste polyethylene and polystyrene were treated with hydro‐cracking to regenerate better fuel for automotive applications (Shafeeq et al., 2022). In the same trend, the waste plastics were converted into C2 fuel via photocatalytic Conversion (Jiao et al., 2020).…”
