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 to a dehydration cleavage reaction zone in the presence of a dehydration cleavage catalyst and reacting at a pressure and temperature sufficient to form a product stream comprising propionaldehyde, a dioxolane component, and a dioxane component; and adding the product stream and hydrogen to a dehydration reaction zone in the presence of a hydrogenation catalyst to form and reacting at a pressure and temperature sufficient to form a second product stream comprising a propanol component. The second product 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 third product stream comprising propylene.

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.
