  • Patent number: 6610195
    Abstract: A process for conversion of hydrocarbon feed by contacting the feed with a catalyst containing heteropoly acid supported on a carrier at reaction conditions being effective in the conversion of the feed, wherein the carrier is selected from substantially inert inorganic amorphous or crystalline material, which retains characteristic structure of the heteropoly acid as evidenced by vibration frequencies around 985 and 1008 cm−1, and which has a surface area larger than 15 m2/g excluding surface area in pores below 15 Å in diameter.

  • Patent number: 5498816
    Abstract: Process for the dehydrogenation of a hydrocarbon feed stream comprising steps of contacting the feed stream with a dehydrogenation catalyst in at least one dehydrogenation zone and reacting the feed stream to a hydrogen containing effluent stream;admixing to the effluent stream an oxygen containing atmosphere in at least one mixing zone;removing hydrogen from the effluent stream by reaction with oxygen in the oxygen containing atmosphere by contact with a hydrogen oxidation catalyst in at least one hydrogen removing zone,the improvement of which comprises employing massive forms of noble metals or alloys thereof as catalyst in the hydrogen removal zone.
