Development of C-C and C-O bond cleavage catalysts for the depolymerization of plastics

Wei-Tse Lee

Chemical recycling of plastics provides more flexibility for materials circulation than landfill disposal or incineration. Intensive research efforts have been devoted to maximizing the efficiency of chemical recycling through catalyst development. The fro ...

Mechanistic classification and benchmarking of polyolefin depolymerization over silica-alumina-based catalysts

Paul Joseph Dyson, Mounir Driss Mensi, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee, Jed Russell Carullo

Carbon-carbon bond cleavage mechanisms play a key role in the selective deconstruction of alkanes and polyolefins. Here, we show that the product distribution, which encompasses carbon range and formation of unsaturated and isomerization products, serves a ...

Direct conversion of plastic materials into methane and liquid fuels

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee

The invention relates to a method for direct conversion of plastic materials into methane and/or liquid fuel and use of ruthenium-modified zeolite to catalyse this conversion. ...

Indirect CO2 Methanation: Hydrogenolysis of Cyclic Carbonates Catalyzed by Ru-Modified Zeolite Produces Methane and Diols

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee, Zhangjun Huang

We report a ruthenium‐modified zeolite which efficiently transforms propylene carbonate to propylene glycol and methane, under solvent‐free conditions. The catalyst achieved high product selectivity and no significant ageing effect was observed after multi ...
