  • Zeolite Catalysts
    Publication number: 20070246400
    Abstract: A process for cracking C4+ hydrocarbons comprising heating the hydrocarbons at a temperature of 400-800° C. in the presence of an H-ZSM-5 catalyst having a silicon to aluminium ratio of 61-1000.
    Type: Application
    Filed: January 5, 2006
    Publication date: October 25, 2007
    Inventors: Klaus Jens, Trond Myrstad, Ivar Dahl, Ase Slagtern
  • Method for in-situ synthesis of crystalline microporous metalloaluminophosphate in a formed body
    Publication number: 20050171394
    Abstract: The invention concerns a method for production of microporous crystalline metalloaluminiumphosphates (ELAPO) based adsorbents or catalysts by in-situ crystallisation of ELAPO inside a formed body. First the formed body containing aluminium phosphate (AlPO) and binder is prepared, thereafter the organic structure directing agent, EL source and water are added and finally ELAPO is crystallised in-situ at elevated temperature and pressure, while keeping the shape and size of the formed body.
    Type: Application

    Inventors: Terje Fuglerud, Arne Gronvold, Rune Wendelbo, Ase Slagtern, Ivar Dahl
  • Method of synthesising crystalline microporous metalloaluminophosphate for a solid body
    Publication number: 20050003956
    Abstract: The invention concerns a simple and cheap method for production of microporous crystalline metalloaluminiumphosphates (ELAPO) for use as adsorbent or catalyst by wholly or partially filling the pores of particles containing aluminium phosphate (AIPO) with an aqueous mixture containing an active source of metal and an organic structure directing agent and perform crystallisation at elevated temperature under autogenous pressure to form crystals of ELAPO.
