  • Hydrodesulfurization catalysts based on supports prepared from rehydratable alumina
    Patent number: 4120826
    Abstract: Disclosed is a method for producing a hydrodesulfurization catalyst and the catalyst produced thereby. The HDS catalyst is prepared by solution impregnation of an alumina catalyst support which has been made from a rehydratable form of alumina.
    Type: Grant
    Filed: June 14, 1976
    Date of Patent: October 17, 1978
    Assignee: American Cyanamid Company
    Inventors: Robert H. Ebel, Donald P. Spitzer, William Edward Bambrick
  • Staged rehydration of alumina
    Patent number: 4120942
    Abstract: Disclosed is a method for forming shaped catalysts from a rehydratable alumina composition. The method includes a staged rehydration procedure to stabilize the rehydratable alumina to facilitate extrusion processing.
    Type: Grant

    Assignee: American Cyanamid Company
    Inventors: Donald P. Spitzer, William Edward Bambrick
  • Process for preparing shaped particles from rehydratable alumina
    Patent number: 4065407
    Abstract: Disclosed is a process for preparing shaped alumina particles for catalysts or catalyst supports by passing droplets of an aqueous slurry of a rehydratable alumina composition through a shaping medium, such as a column of water-immiscible liquid. The alumina composition undergoes rehydration while being shaped as it passes through the shaping medium, and accordingly, firm, discrete alumina bodies are produced.
