ABSTRACT:

Bifunctional catalysts characterized by a zeolite support giving acidity and a noble metal for hydro-deshydrogenating function are promising for isomerization. They operate at 250(sup 0)C and tolerate a certain level of impurity. Influence of Si/Al ratio on activity, selectivity and stability of hydroisomerization is investigated. Kinetic study of n-hexane isomerization, transformation of cyclohexane and methylcyclopentane and their influence on n-hexane isomerization, isomerization of n-heptane and n-butane, to determine hydrocarbon chain length dependence, are examined.
