Extrusion additive manufacturing process for producing polyethylene articles

A nano platelet gibbsite treated with compound of formula (OR)Si&#x2014;Ror of formula R&#x2014;COOH wherein Requal to or different from each other is a C-Calkyl radical; Ris a C-Chydrocarbon radical and Ris a C-Chydrocarbon radical is used as a catalyst support.

Supported catalyst system

Methods of depolymerizing polyolefin-based material into useful petrochemical products using metal oxides and heat are described. The metal oxides improve the depolymerization reaction by decreasing the onset temperature for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.

Polyolefin depolymerization with metal oxides

A method of depolymerizing plastics using a halloysite catalyst is described herein. The method reduces the energy required for the depolymerization process while achieving improved depolymerization results.
