Abstract: Methods for gas-phase deoxygenation of a bio-oil are provided. In embodiments, such a method comprises exposing a bio-oil vapor comprising hydrocarbon compounds having oxygenated aromatic groups, to hydrogen gas in the presence of catalyst under conditions to induce deoxygenation of the oxygenated aromatic groups to provide a deoxygenated aromatic species, wherein the catalyst is a transition metal-incorporated mesoporous silicate having platinum deposited thereon and the transition metal is selected from Nb, W, Zr, and combinations thereof. The transition metal-incorporated mesoporous silicate catalysts are also provided.

Abstract: A process for epoxidizing an olefin comprising contacting an olefin with an oxidant in the presence of an insoluble oxidation catalyst in a solvent system comprising an organic water-miscible solvent to form an alkylene oxide. The insoluble oxidation catalyst comprises a metal, preferably selected from the group consisting of tungsten, cerium, and niobium. The metal is directly incorporated within a solid mesoporous silicate support, such as one selected from the group consisting of KIT-5, KIT-6, and TUD-1.
