  • Catalyst composition and catalytic processes for producing liquid hydrocarbons
    Patent number: 10589257
    Abstract: The invention relates to potassium-promoted, Fe2+(Fe3+yAl3+i-y)2o4 [0.3<y?0.7] silica-containing extrudates, processes for the preparation of the extrudates with the aid of colloidal silica, and the use of the extrudates to catalyze processes for producing liquid hydrocarbons.
    Type: Grant
    Filed: April 6, 2016
    Date of Patent: March 17, 2020
    Assignee: B.G. Negev Technologies and Applications Ltd., at Ben-Gurion University
    Inventors: Mordechay Herskowitz, Miron Landau, Roksana Vidruk, Meital Amouyal

  • Catalysts based on silicoaluminophosphate SAPO-11 and uses thereof
    Patent number: 10399067
    Abstract: The invention provides a process for preparing SAPO-11, that comprises combining in an aqueous solution alumina source, P 2 O source and a silica source in the presence of a crystallization template and a surfactant to form a gel, which is then subjected to hydrothermal crystallization and calcination. The so-formed SAPO-11, which possesses unique silicon distribution, high resistance to hydrothermal degradation (desilication) and high surface area, forms another aspect of the invention. Hydroprocessing of a vegetable oil in the presence of a catalyst comprising the Pt and SAPO-11 of the invention is also demonstrated.
