Selective conversion of HDPE to waxes via thermocatalytic deconstruction
A novel process to selectively convert HDPE waste into valuable hydrocarbon waxes using thermocatalytic deconstruction. The process optimizes solvent-catalyst-polymer interactions to control product selectivity, enabling the production of high-value waxes for lubricants and coatings.
Overview
This innovative technology focuses on the selective thermocatalytic deconstruction of post-consumer high-density polyethylene (HDPE) into valuable hydrocarbon waxes. By optimizing the interactions between solvents, catalysts, and polymers, the process enhances selectivity and efficiency, enabling the production of waxes with controlled molecular weight distributions. These waxes have significant applications in high-performance lubricants, adhesives, and coatings, offering a sustainable solution to upcycle plastic waste and mitigate environmental pollution.
