Yunxian Zhu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metal loaded catalyst and preparation method thereof
    Patent number: 9643172
    Abstract: A metal loaded catalyst comprises a support and main active metal components and optional auxiliary active metal components, wherein the main active metal components are elementary substances and obtained by ionizing radiation reducing precursors of main active metal components. The catalyst can be widely used in the catalytic reactions of petrochemistry industry with high activity and selectivity. The catalyst can be used directly without being reduced preliminarily by hydrogen.
    Type: Grant

  • Catalyst for selective hydrogenation
    Patent number: 6627578
    Abstract: A catalyst for selective hydrogenation, which comprises, on the basis of the total weight of catalyst, 1-30 wt % of copper as the first active component, 0.001-5 wt % of palladium as the second active component, 0.001-6 wt % of at least one metal selected from Ag, Pt, Pb, Mn, Co, Ni, Cr, Bi, Zr and Mo as cocatalyst, and the balance of at least one support selected from alumina, silica or titania. The present invention further relates to its preparation, its use in removal of alkynes from alkyne-enriched C4 cuts through selective hydrogenation and its regeneration.
