Process for the isomerization of normal paraffins in presence of at least a catalyst supported on a given zeolithe omega.

摘要

Process for the isomerisation of normal, particularly C5-C6 paraffins in the presence of at least one catalyst based on an omega zeolite which has an SiO2/Al2O3 molar ratio of between 6.5 and 80, a sodium weight content of less than 0.2%, crystal parameters "a" and "c" which are respectively smaller than or equal to 1.814 nm and 0.760 nm, a nitrogen adsorption capacity, measured at 77 K at a partial pressure of 0.19, which is greater than approximately 8 % by weight, the said catalyst additionally including at least one metal of group VIII of the Periodical Classification of the elements, preferably platinum and/or palladium.
