  • Solid phosphoric acid with controlled porosity
    Patent number: 8063260
    Abstract: The present invention relates to a solid phosphoric acid catalyst and a process for conversion of hydrocarbons using a solid phosphoric acid catalyst. The solid phosphoric acid catalyst comprises silicon orthophosphate, and has a silicon orthophosphate to silicon pyrophosphate ratio of at least about 5:1. The total pore volume of the solid phosphoric acid catalyst is at least about 0.17 cm3 per gram of catalyst, of which at least about 0.15 cm3 per gram is contributed by pores with diameter of at least about 10,000 ?.
    Type: Grant
    Filed: July 7, 2009
    Date of Patent: November 22, 2011
    Assignee: Sud-Chemie Inc.
    Inventors: Ling Xu, Wayne Turbeville, Gregory A. Korynta, Jeffrey L. Braden
