INTRODUCTION
The isomerization of normal kerosenes (or linear alkanes) with four, five and six carbon atoms into isoparaffins (or branched alkanes) with better anti-knock properties is used to obtain high-octane products for fuel formulation, mainly from petroleum direct distillation cuts (petroleum cuts 30 – 80 °C), or from C 4 cuts in the case of n-butane leading to the production of isobutane, the basic reagent for the aliphatic alkylation process .
