    Patent number: 4159257
    Abstract: The improvment of the preferred Pt-Sn on alumina bimetallic catalyst (and similar catalysts) for hydrotreatment of hydrocarbons, comprising the catalyst further containing silicon in combined form.
    Type: Grant
    Filed: April 4, 1977
    Date of Patent: June 26, 1979
    Assignee: Compagnie Francaise des Petroles

  • Catalysts for the hydrotreatment of hydrocarbons and a process for the preparation and utilization thereof
    Patent number: 4071437
    Abstract: Catalysts are disclosed for the hydrotreatment of hydrocarbons, and particularly for reforming, which contain no platinum and which consist of:A refractory-mineral carrier (alumina).0.05 to 5 wt. % of at least one first metal from the group consisting of iron, cobalt, and nickel.At least one second metal from the group consisting of tin (0.01 to 5%), lead (0.01 to 10%), and germanium (0.01 to 4%).Possibly from 0.01 to 0.5% of sulfur.Processes for preparation of these catalysts, by impregnation, and for their use are disclosed. It is preferable to deposit the metal (or the metals) from the tin-germanium-lead group before the metal or metals from the iron-cobalt-nickel group are deposited.
