  • Catalyst containing metal cluster in structurally collapsed zeolite, and use thereof
    Patent number: 10406510
    Abstract: This invention relates to a hydrogen spillover-based catalyst and use thereof, wherein a hydrogen activation metal cluster is dispersed in the form of being encapsulated in a crystalline or amorphous aluminosilicate matrix which is partially or fully structurally collapsed zeolite, thereby exhibiting high hydroprocessing or dehydrogenation activity and suppressed C—C hydrogenolysis activity.
    Type: Grant
    Filed: October 26, 2018
    Date of Patent: September 10, 2019
    Assignees: SK INNOVATION CO., LTD., KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Min Kee Choi, Ju Hwan Im, Do Woan Kim, Do Kyoung Kim, Tae Jin Kim, Seung Hoon Oh, Tae Hong Seok
  • Transition metal-noble metal complex oxide catalyst for dehydrogenation prepared by one-pot synthesis and use thereof
    Patent number: 10307737
    Abstract: Disclosed are a complex oxide catalyst for dehydrogenation, a method of preparing the same, and use thereof, wherein the catalyst includes a first transition metal selected from the group consisting of gallium, vanadium, chromium, manganese, molybdenum, and zinc, a hydrogen-activating metal including at least one selected from the group consisting of Groups 8, 9, 10, and 11 elements in a periodic table, and alumina, the amount of the first transition metal being 0.1 wt % to 20 wt %, the amount of the hydrogen-activating metal being 0.01 wt % to 2 wt %, based on the amount of the alumina, the first transition metal being loaded on the alumina, and the hydrogen-activating metal being surrounded by the alumina.
