  • Low pressure naphtha hydrocracking process
    Patent number: 6709571
    Abstract: This invention is directed to an extinction recycle naphtha hydrocracking processes. Large pore zeolite catalysts with Constraint Indices less than 2, such as USY or beta, which are loaded with noble metals such as Pt or Pd or with transition metals such as Ni in combination with Mo or W are employed. Preferably, low hydrogen partial pressures, and a feedstock relatively rich in hydrogen and low in aromatics content, are used, in order to extend catalyst cycle length.
    Type: Grant
    Filed: July 20, 1999
    Date of Patent: March 23, 2004
    Assignee: Mobil Oil Corporation
    Inventors: Kenneth J. Del Rossi, David A. Pappal, Brenda H. Rose
  • Supported heteropoly acid catalysts
    Patent number: 5475178
    Abstract: There is provided a catalyst comprising a heteropoly acid, such as phosphotungstic acid, supported on a mesoporous crystalline material, such as M41S. A particular form of this M41S support is designated as MCM-41. There is also provided a method for preparing this catalyst by impregnating the heteropoly acid on the support. There is also provided a process for using this catalyst to catalyze acid catalyzed reactions, such as the isomerization of paraffins and the alkylation of aromatics.
    Type: Grant

  • Supported heteropoly acid catalysts for isoparaffin-olefin alkylation reactions
    Patent number: 5324881
    Abstract: The alkylation of isoparaffin with olefin to provide alkylate is carried out in the presence of, as catalyst, a supported heteropoly acid. The support may be MCM-41, and the heteropoly acid may be dodecawolframophosphoric acid (i.e., phosphotungstic acid, i.e., H.sub.3 PW.sub.12 O.sub.40).
