  • Patent number: 10329209
    Abstract: A process for preparing C2 and C3 olefins comprises contacting a feedstream including hydrogen, carbon monoxide, and a bifunctional catalyst in a reaction under certain specified conditions. The catalyst includes as components (1) chromium oxide and zinc oxide mixed metal oxides, and (2) a SAPO-34 molecular sieve. The resulting product of the reaction is relatively high in the target lower olefins and relatively low in less desirable products, including C2 and C3 paraffins, C4+ hydrocarbons, oxygenates, and methane, thereby reducing or eliminating the need for certain previously common and costly separations. The bifunctional catalyst as used in the inventive process also offers improvements in catalyst life in comparison with some methanol-to-olefins catalysts. The process may be carried out as a single unit operation.

  • Patent number: 9005552
    Abstract: Provided is a new catalyst capable of removing carbon monoxide economically without adding particular reaction gas externally. Also provided are a process for producing and an apparatus using such a catalyst. Impregnation of a Ni—Al composite oxide precursor of a nonstoichiometric composition prepared by the solution-spray plasma technique with a ruthenium salt to be supported and performing reduction treatment allows CO methanation reaction to selectively proceed even in the high-temperature range in which CO2 methanation reaction and reverse water-gas-shift reaction proceed preferentially with conventional catalysts. Selective CO methanation reaction occurs reproducibly with another Ni—Al composite oxide precursor or an additive metallic species.

  • Patent number: 9006131
    Abstract: A composite oxide for an exhaust gas purification catalyst is provided which can burn PM in diesel engine exhaust gas at low temperatures and has a good S desorption property. The composite oxide for an exhaust gas purification catalyst is composed of Ce, Bi, Pr, R, and oxygen in a molar ratio of Ce:Bi:Pr:R=(1?x?y?z):x:y:z. The ratios of Ce, Bi, Pr, and R satisfy 0<x+y+z?0.5 and preferably 0<x?0.1, 0<y?0.25, and 0<z?0.3. Particularly, when R is Zr, the composite oxide exhibits a good S desorption property at a temperature of about 600° C. and can recover its catalytic activity at low temperatures. Therefore, the exhaust gas purification catalyst is suitable as a PM combustion catalyst.

  • Publication number: 20150099622
    Abstract: A method for preparing a catalyst having catalytically active materials selectively impregnated or supported only in the surface region of the catalyst particle using the mutual repulsive force of a hydrophobic solution and a hydrophilic solution and the solubility difference to a metal salt precursor between the hydrophobic and hydrophilic solutions. The hydrophobic solvent is a C2-C6 alcohol. The hydrophobic solvent is introduced into the catalyst support and then removed of a part of the pores connected to the outer part of the catalyst particle by drying under appropriate conditions. Then, a hydrophilic solution containing a metal salt is introduced to occupy the void spaces removed of the hydrophobic solvent, and the catalyst particle is dried at a low rate to selectively support or impregnate the catalytically active material or the precursor of the catalytically active material only in the outer part of the catalyst particle.

  • Patent number: 8999283
    Abstract: In one embodiment, carbon dioxide is converted into a chemical feedstock by providing a mixture of plasmonic material and oxygen-conducting material, exposing the mixture to sunlight so that solar energy is absorbed by the plasmonic material which then heats the oxygen-conducting material so that oxygen vacancies are generated, passing carbon dioxide through the mixture, and the oxygen-conducting material removing oxygen atoms from the carbon dioxide to form carbon monoxide.
