Abstract
Process for isomerization of paraffinic feedstocks operating at a temperature of between 200° C. and 500° C., at a total pressure of between 0.45 MPa and 7 MPa, at a partial pressure of hydrogen of between 0.3 and 5.5 MPa, at an hourly space velocity of between 0.1 and 10 kg of feedstock introduced per kg of catalyst and per hour, using a catalyst having at least one group VIII metal, at least one matrix and at least one IZM-2 zeolite, the total weight content of alkali metal and/or alkaline-earth metal elements is less than 200 ppm by weight relative to the total mass of said catalyst.
