    • The invention concerns a process for selective hydroisomerization of compounds with an n-alkane chain containing more than 10 carbon atoms, in which the compound to be treated is brought into contact with a catalyst comprising at least one hydro-dehydrogenating element and at least one molecular sieve having a one- or two-dimensional pore network, the accessible pore openings of which are delimited by 10 oxygen atoms, and a distance termed the bridging distance between the pores of less then 0.70 nm, and the zeolite is such that a catalyst which undergoes a standard n-heptadecane isomerization test has, for a conversion of 95%, a selectivity of at least 70% for isomerized products, and the catalyst contains at least 5% by weight of at least one hydro-dehydrogenating element selected from the group formed by non noble GVIII metals, GVIB metals, and niobium, and the catalyst preferably contains phosphorous. The sieve is preferably a NU-10, NU-23, NU-87, EU-13 or Theta-1 zeolite.
