    3. Effect of the physico-chemical properties of bifunctional catalysts

    The hydroisomerization of long-chain n-alkanes over bifunctional Pt/H zeolite catalysts, a transformation for which the effect of the physico-chemical characteristics of the bifunctional catalysts (concentration of their redox sites and accessible proton acid sites and ratio of these concentrations, spatial organization and pore size of the zeolites, etc.) is the most precisely established, was naturally chosen.

    3.1 Influence of the "balance" between hydrogenating and acid functions

    The quantitative effect of this "balance" was established for the first time in the transformation of n-heptane (n-C 7 )
