  • Publication number: 20110230572
    Abstract: Improved reaction efficiencies are achieved by the incorporation of enhanced hydrothermally stable catalyst supports in various water-forming hydrogenation reactions or reactions having water-containing feeds. Examples of water-forming hydrogenation reactions that may incorporate the enhanced hydrothermally stable catalyst supports include alcohol synthesis reactions, dehydration reactions, hydrodeoxygenation reactions, methanation reactions, catalytic combustion reaction, hydrocondensation reactions, and sulfur dioxide hydrogenation reactions. Advantages of the methods disclosed herein include an improved resistance of the catalyst support to water poisoning and a consequent lower rate of catalyst attrition and deactivation due to hydrothermal instability. Accordingly, higher efficiencies and yields may be achieved by extension of the enhanced catalyst supports to one or more of the aforementioned reactions.

  • Publication number: 20080183020
    Abstract: Catalytic reactions are taught for air or oxygen oxidative chemical conversion of primary alcohols to aldehydes, glycol ethers and related products and secondary alcohols to ketones and related products at ambient pressure. The catalytic process converts ethanol to acetaldehyde and 2-ethoxyethanol, n-propanol to propionaldehyde and its glycol ethers, 2-propanol to acetone, and other reactants to similar products. The catalysts are based on molecular strings of di-, tri- and/or poly- groups of transition metal complexes possessing a degree of symmetry. Laboratory results have demonstrated [manganese (II)]2, [cobalt (II)]2, [vanadium (II)]2 and similar families of catalysts to be effective for oxidative catalytic conversion of primary alcohols to products comprising related aldehydes and glycol ethers, and secondary alcohols to products comprising ketones and related products.

  • Patent number: 7297324
    Abstract: Microchannel devices and method of use are disclosed wherein a reaction microchamber 52 is in thermal contact with a heat exchange channel 61. An equilibrium limited exothermic chemical process occurs in the reaction microchamber 52. Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamber 52 down its length to substantially increase at least one performance parameter of the exothermic chemical process relative to isothermal operation. Optionally, an endothermic reaction occurs in the heat exchange channel 61 which is sustained by the exothermic chemical process occurring the exothermic reaction chamber. Both the reaction chamber 52 and the heat exchange channel 61 can be of micro dimension. Catalyst 75 can be provided in the microchamber 52 in sheet form such that reactants flow by the catalyst sheet.
