Provided herein is an alkane dehydrogenation catalyst, a method of manufacturing an alkane dehydrogenation catalyst, and a method of converting alkanes to alkenes.

Alkane dehydrogenation catalyst and methods of converting alkanes to alkenes

A multimetallic catalyst having a substrate, intermediate layer and catalyst layer. The catalyst exhibits selectivity greater than 90% and a conversion rate of greater than 30%.

Multimetallic catalysts

A high surface area catalyst with a mesoporous support structure and a thin conformal coating over the surface of the support structure. The high surface area catalyst support is adapted for carrying out a reaction in a reaction environment where the thin conformal coating protects the support structure within the reaction environment. In various embodiments, the support structure is a mesoporous silica catalytic support and the thin conformal coating comprises a layer of metal oxide resistant to the reaction environment which may be a hydrothermal environment.

Hydrothermal performance of catalyst supports

Highly uniform cluster based nanocatalysts supported on technologically relevant supports were synthesized for reactions of top industrial relevance. The Pt-cluster based catalysts outperformed the very best reported ODHP catalyst in both activity (by up to two orders of magnitude higher turn-over frequencies) and in selectivity. The results clearly demonstrate that highly dispersed ultra-small Pt clusters precisely localized on high-surface area supports can lead to affordable new catalysts for highly efficient and economic propene production, including considerably simplified separation of the final product. The combined GISAXS-mass spectrometry provides an excellent tool to monitor the evolution of size and shape of nanocatalyst at action under realistic conditions. Also provided are sub-nanometer gold and sub-nanometer to few nm size-selected silver catalysts which possess size dependent tunable catalytic properties in the epoxidation of alkenes. Invented size-selected cluster deposition provides a unique tool to tune material properties by atom-by-atom fashion, which can be stabilized by protective overcoats.

Subnanometer and nanometer catalysts, method for preparing size-selected catalysts

A two phase catalyst is disclosed with one or more transition metals such as Cu, Co, Fe, Ag and Mo supported on a molecular sieve having a pore size not greater than 8 &#x212b; along with a stabilizing oxide of one or more of the oxides of Zr, Mo, V, Nb or the rare earths coating the molecular sieve. A method of preparing the two phase catalyst and using same to remediate NOin combustion gases is also described.

A process and apparatus are provided for in-situ production of hydrogen (H ) by alcohol decomposition for emission reduction from internal combustion engines. Hydrogen is generated by a catalytic process for in-situ production from alcohols, either neat, or in a hydrocarbon mixture, such as gasoline. The in-situ production of hydrogen is achieved using a solid basic catalytic bed provided with the internal combustion engine. The preferred catalyst is a copper (Cu) containing layered double hydroxide (LDH)-derived catalyst, such as a Cu/Al LDH-derived catalyst. At least a portion of an alcohol containing fuel is passed through the catalyst bed to generate hydrogen gas from the alcohol substantially without producing carbon monoxide. The fuel and generated hydrogen gas is injected into the internal combustion engine. Catalytic reactions are provided at temperatures in a range between ambient and 500&deg; C., preferably between 150&deg; C. through 400&deg; C.

A method for encapsulating hazardous cations is provided comprising supplying a pretreated substrate containing the cations; contacting the substrate with an organo-silane compound to form a coating on the substrate; and allowing the coating to cure. A medium for containing hazardous cations is also provided, comprising a substrate having ion-exchange capacity and a silane-containing coating on the substrate.

A process for efficiently converting methanol to C.sub.3 -C.sub.12 olefins or paraffinic gasoline components is disclosed. A gaseous reaction mixture containing methanol and olefins is contacted with a solid acid catalyst in a reaction zone under conditions whereby a positive methanol concentration is maintained throughout the reaction zone. The process provides extended catalyst life, reduced deactivation rates, improved yields, and enhanced selectively for valuable products.
