Abstract: Processes for conversion of propylene polyol feed into useful petrochemical products, including olefin monomers, are described. Such processes comprise: adding a feed stream comprising one or more propylene polyols, hydrogen, and optionally water, to a catalytic conversion reaction zone in the presence of a first solid acid catalyst component and a hydrogenation catalyst component and reacting at a pressure and temperature sufficient to form a first product stream comprising a propanol component. The first product stream can be added to a dehydration reaction zone in the presence of a dehydration catalyst and reacted at a pressure and temperature sufficient to form a second product stream comprising propylene.

Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using supported metal oxides and heat are described. The supported metal oxides improve the depolymerization reaction by decreasing the half time 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.

Abstract: Pre-treatment methods for polyolefin-based feed streams before depolymerization are described. Polyolefins are separated from other material in the polyolefin-based feed stream using density differences in an aqueous solution, which allows for a pre-treatment method that does not affect the depolymerization catalyst. By removing the non-polyolefin materials from the feed stream, the depolymerization of the polyolefin material can proceed at lower temperatures for longer cycles. This results in a more efficient process with a smaller carbon footprint.

Abstract: 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.

Abstract: Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The compositions are a composite of at least one zeolite catalyst with one or more co-catalyst(s) that is a solid inorganic material. These composite catalysts, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of non-polyolefin polymers that may be present. This results in a shorter residence time in the depolymerization unit and more efficient process.

Abstract: Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The catalytic compositions are mixed metal oxides demonstrating equal or higher conversion than noncatalytic pyrolysis. These mixed metal oxide catalysts and a polyolefin-based material are heated in the presence of oxygen to form a product comprising one or more olefin monomers.

Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using styrene oligomers or polymers, and heat are described. The styrene oligomers or polymers improve the depolymerization reaction by decreasing the halftime 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.
