摘要： The invention relates to a process for isomerizing normal paraffins, particularly C.sub.5 -C.sub.6, in the presence of at least one catalyst based on an omega zeolite having a molar ratio SiO.sub.2 /Al.sub.2 O.sub.3 ranging from 6.5 to 80, a content by weight of sodium lower than 0.2%, crystalline parameters "a" and "c" respectively smaller than or equal to 1.814 nm and 0.760 nm, a capacity of adsorption of nitrogen, measured at 77K under a partial pressure of 0.19, higher than about 8% by weight, the catalyst also comprising at least one metal from group VIII of the periodic table of elements, preferably platinum or/and palladium.
