Plastic Waste Conversion over a Refinery Waste Catalyst

Ina Vollmer et al.

Summary: Research has shown that industrial Fluid Catalytic Cracking catalyst can effectively convert polypropylene, and through separate testing, the limitations of transmission have been revealed. The equilibrium catalyst produced the same aromatic content as the fresh catalyst, but with less coke formation, likely due to reduced activity of the zeolite domains and enhanced cracking activity of the matrix.

Low-temperature catalytic upgrading of waste polyolefinic plastics into liquid fuels and waxes

Yosuke Nakaji et al.

Summary: A new low-temperature catalytic method using CeO2-supported Ru (Ru/CeO2) catalyst has been developed for upgrading waste polyolefinic plastics to valuable chemicals such as liquid fuels and waxes, with high yields of 92%. This catalyst is effective in hydrogenolysis of various polyethylenes and polypropylene, providing valuable chemicals with yields ranging from 83% to 90%. Additionally, commercial plastic bags and waste polyethylenes can be transformed to valuable chemicals with yields of 91% and 88%, respectively.

Impact of Heteroatom Speciation on the Activity and Stability of Carbon-Based Catalysts for Propane Dehydrogenation

Simon Buchele et al.

Summary: The study focuses on different porous properties, heteroatom types, contents, and specifications in polyaniline-derived and activated carbon platforms. The main functionality governing activity is carbonyl groups, and the main deactivation path is oxygen loss via propane-driven water evolution. Carbon catalysts derived from KOH-post-treated polyanilines show significantly enhanced stability compared to others, highlighting the importance of controlling nanostructure for longevity.

Conversion of Polyolefin Waste to Liquid Alkanes with Ru-Based Catalysts under Mild Conditions

Julie E. Rorrer et al.

Summary: Chemical upcycling of waste polyolefins via hydrogenolysis using Ru/C catalysts demonstrates high activity and selectivity in the conversion of polyethylene into liquid alkanes and light alkane gases under mild conditions. The study also shows the feasibility of producing C-7-C-45 alkanes from long chain, low-density polyethylene and postconsumer LDPE plastic bottles, providing promising pathways for plastic waste valorization using Ru-based catalysts.
