  • Process for the hydration of mixed butenes to produce mixed alcohols
    Patent number: 9593059
    Abstract: Mixed butenes from a cracking process, or raffmates of MTBE or tert-butyl alcohol (TBA), are simultaneously hydrated using water in the presence of a catalyst to produce sec-butyl alcohol (SBA) and tert-butyl alcohol as the principal products, the mixed butanols having utility as fuel additives, e.g., as oxygenates and octane enhancers to replace MTBE, and as a neat fuel.
    Type: Grant
    Filed: January 9, 2012
    Date of Patent: March 14, 2017
    Assignee: SAUDI ARABIAN OIL COMPANY
    Inventors: Wei Xu, Farhan M. Al-Shahrani, Abdennour Bourane, Stephan Ralf Vogel
  • Olefin hydration process with an integrated membrane reactor

  • Hydrated niobium oxide nanoparticle containing catalysts for olefin hydration
    Patent number: 8629080
    Abstract: An olefin hydration catalyst and method for producing same is provided. The olefin hydration catalyst can be prepared by contacting a niobium containing compound with a strong Bronsted acid, such as sulfuric or phosphoric acid, to produce niobium oxo sulfate or niobium oxo phosphate nanoparticles. The nanoparticles can be separated, dried and utilized in a reactor for the hydration of olefins to their corresponding alcohols.
