The Scott Group Publishes New Findings on Plastic Upcycling in Chem
Recent publication from the Scott Group demonstrates improvement in their innovative process that turns polyolefin into high-value alkylaromatics.
UCSB researchers in collaboration with researchers at the University of Illinois, Urbana-Champaign, Cornell University, and the Institute for Cooperative Upcycling of Plastics continue to tackle the global plastic waste problem. In the original process of turning polyethylene into long chain alkylaromatics, the platinum on alumina catalyst was slow and the yield of products low. In the improved process, the speed and selectivity of the reaction is enhanced by increasing the acidity of the alumina via the addition of chlorine or fluorine. This process enhances the viability of chemical upcycling as an alternative to mechanical recycling.
