Isomerization of Hexane on Nickel Catalysts Supported on Modified Montmorillonite

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Nickel catalysts supported on activated montmorillonite modified with titanium dioxide and mordenite were prepared by various methods. The catalytic properties of these catalysts in the isomerization of hexane were studied. The greatest hexane conversion (36.2%) was achieved on a nickel catalyst supported on activated montmorillonite modified with mordenite and TiO2 introduced by mixing the components. The optimal composition of the catalyst at 350°C and 1 atm gave the conversion of hexane into C4C7 isomers in 34.2% yield and 93.6% selectivity. Among the catalysts studied, this composition has the greatest specific surface, greatest amount of mesopores, as well as greatest total content of weak and medium-strength acid sites.
