1. A process for the reforming of a hydrocarbon feedstock comprising contacting the feedstock with a reforming catalyst at reforming conditions to obtain an aromatics-rich effluent stream, the catalyst comprising:

  • (a) a nonacidic large-pore molecular sieve having a unit empirical formula on an anhydrous basis of mA;

    (SnwAlxSiy)O2;

    where A is at least one exchangeable cation selected from the group consisting of alkali and alkaline earth metals, “

    m”

    is the mole fraction of A and varies from about 0.01 to about 0.49, “

    w”

    is the mole fraction of tin and varies from about 0.01 to about 0.49, “

    x”

    is the mole fraction of aluminum and varies from about 0.01 to about 0.49, and “

    y”

    is the mole fraction of silicon and varies from about 0.50 to about 0.98;

    (b) a platinum-group metal component; and

    , (c) an non-acid inorganic-oxide binder.
