  • Patent number: 10850270
    Abstract: Disclosed is a method for preparing a carbon-supported metal oxide and/or alloy nanoparticle catalyst. According to the method, a carbon-supported metal oxide and/or alloy nanoparticle catalyst is prepared by depositing metal oxide and/or alloy nanoparticles on a water-soluble support and dissolving the metal oxide and/or alloy nanoparticles deposited on the water-soluble support in an anhydrous polar solvent containing carbon dispersed therein to support the metal oxide and/or alloy nanoparticles on the carbon. The anhydrous polar solvent has much lower solubility for the water-soluble support than water and is used to dissolve the water-soluble support.

  • Patent number: 10800717
    Abstract: The present invention relates to a palladium-based supported hydrogenation catalyst and a preparation method and application thereof. The catalyst is prepared by the following method: impregnating an Al2O3-containing carrier with an organic solution containing a bipyridine derivative having hydroxy group, optionally drying followed by impregnating with a mixed solution containing the main active component palladium ions and the auxiliary active component Mn+ ions, where M is one selected from Ag, Au, Ni, Pb and Cu; and then optionally drying, and calcining to obtain the catalyst. The preparation method provided by the present invention allows Pd atoms and M atoms to be highly uniformly dispersed on the carrier, which overcomes the adverse impact of the surface tension of the impregnation solution and the solvation effect on the dispersibility of active components.

  • Patent number: 10702854
    Abstract: A process of methane catalytic conversion produces olefins, aromatics, and hydrogen under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750-1200° C.; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000-30000 ml/g/h; and fixed bed), conversion of methane is 8-50%. The selectivity of olefins is 30-90%. And selectivity of aromatics is 10-70%. The catalyst for this methane conversion has a SiO2-based matrix having active species that are formed by confining dopant metal atoms in the lattice of the matrix.
