Tandem catalysts for the dehydrogenation of alkanes and/or alcohols in tandem with selective hydrogen combustion are provided. Also provided are methods of making the catalysts and methods of using the catalysis for the dehydrogenation of alkanes and/or alcohols. The catalysts include a support having a surface, dehydrogenation catalysts particles dispersed on the surface of the support, and a porous selective hydrogen combustion catalyst overcoat on the dehydration catalyst particles. The catalysts couple dehydrogenation with selective hydrogen combustion in a sequence of reactions occurring in tandem to shift the equilibrium of the dehydrogenation towards higher conversion.

Tandem catalysis for alkane and alcohol dehydrogenation coupled to selective hydrogen combustion

A method of producing a polyether alcohol that includes feeding an initiator into a reactor, feeding one or more monomers into the reactor, feeding a polymerization catalyst into the reactor, the polymerization catalyst being a Lewis acid catalyst having a general formula M(R)(R)(R)(R), separate from feeding the initiator into the reactor, feeding a hydrogen bond acceptor additive into the reactor, the hydrogen bond acceptor additive being a Cto Corganic molecule having at least two hydroxyl groups, of which two hydroxyl groups are situated in 1,2-, 1,3-, or 1,4-positions on the organic molecule, and allowing the initiator to react with the one or more monomers in the presence of the polymerization catalyst and the hydrogen bond acceptor additive to form a polyether alcohol having a number average molecular weight greater than a number average molecular weight of the initiator.

A composition and method for producing the same are provided. The composition includes transition metal oxides adhered to a surface of a cerium oxide support, and can additionally include alkali metal or alkaline earth metal promotors. The method includes incipient wetness impregnation of the support with metal salt in solution, and can include impregnation with a metal chelator salt. The composition can be useful as a catalyst for the reduction of noxious gases in combustion exhaust streams. The composition can be of particular use as a component of an automobile catalytic converter, for the specific catalytic reduction of nitrogen oxides to nitrogen gas.
