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: 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.
