    Abstract: A new catalyst for the selective conversion of isobutane to isobutylene. This catalyst also could be applied to the selective dehydrogenation of other light paraffins such as propane and n-butane. The catalyst is comprised of platinum, tin, and potassium supported on K--L-zeolite. This catalyst exhibits greater than 98% selectivity for conversion of isobutane to isobutylene at isobutane conversion levels greater than 50%. In addition, this catalyst exhibits excellent stability. The preferred catalyst would have an atomic ratio of Sn to Pt greater than 1.0 as well as an atomic ratio of K to Pt greater than 1.0.

    Abstract: Disclosed are methods for generating propylene glycol, ethylene glycol and other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols from biomass using hydrogen produced from the biomass. The methods involve reacting a portion of an aqueous stream of a biomass feedstock solution over a catalyst under aqueous phase reforming conditions to produce hydrogen, and then reacting the hydrogen and the aqueous feedstock solution over a catalyst to produce propylene glycol, ethylene glycol and the other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols. The disclosed methods can be run at lower temperatures and pressures, and allows for the production of oxygenated hydrocarbons without the need for hydrogen from an external source.
