  • ADSORBENT FOR DIENES REMOVAL FROM LIQUID AND GAS STREAMS
    Publication number: 20080194902
    Abstract: It is now possible to purify diene-contaminated liquid and gas streams by treating these streams with adsorbents comprising single or multiple transition metal polycation-exchanged faujasites having silicon to aluminum ratio from 0.9 to about 9.0, wherein said transition metal (Tr) polycations have the general formula [Tr?O?]n+, wherein a varies from 2 to 8, ?—from 0 to 4, and n—from 1 to 3 and wherein said transition metals include IB. IIB, VIIB and VIII Group metals preferably selected from the group consisting of copper, cadmium, zinc, manganese, nickel and iron.

  • Process of paraffin isomerization and heteropoly acids supported on inert supports as isomerization catalysts
    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.
    Type: Grant
