  • Hydroisomerization process and catalyst
    Patent number: 4149993
    Abstract: A process for the hydroisomerization of paraffinic hydrocarbons employing a catalyst composed of a noble metal, alumina and chlorine. The catalyst is prepared by treating a composite of noble metal and alumina with an aluminum compound such as an inorganic or organic salt of aluminum, preferably aluminum nitrate, calcining the treated composite and thereafter contacting the treated composite with a conventional chloride activating agent. By treating and calcining the composite with an aluminum salt, the amount of noble metal retained on the catalyst's surface during chloride activation is maximized enabling high conversions of normal paraffins to isoparaffins to be realized.
    Type: Grant
    Filed: March 6, 1978
    Date of Patent: April 17, 1979
    Assignee: Texaco Inc.
    Inventors: Babu Y. Rao, John T. Nolan, Jr., John H. Estes
  • Recovery of ethers
    Patent number: 4144138
    Abstract: Methyl tertiary butyl ether may be recovered from etherification reaction effluent by azeotropic distillation to recover methanol-ether azeotrope overhead which is water-washed to give pure ether raffinate plus ether-methanol bottoms, the latter being azeotropically distilled to yield ether-methanol overhead which is recycled to water-washing.

  • Hydroisomerization of normal paraffin with a catalyst of noble metal, alumina support and chlorine
    Patent number: 4113789
    Abstract: A process for the hydroisomerization of paraffinic hydrocarbons employing a catalyst composed of a noble metal, alumina and chlorine. The catalyst is prepared by treating a composite of noble metal and alumina with an aluminum compound such as an inorganic or organic salt of aluminum, preferably aluminum nitrate, calcining the treated composite and thereafter contacting the treated composite with a conventional chloride activating agent.
