A new field of catalytic application of H-mordenite is shown for manufacturing gasoline blending components of high octane number and free of benzene in order to satisfy environmental and human health regulations. Experiments were carried out with catalysts containing 0. 3-0. 5 % platinum on the zeolite and alumina. Light gasoline fractions containing 0-4. 9 % benzene, 9. 6-10. 3 % C6-cycloalkanes, in excess C6-paraffins (that is the precursors of benzene in naphtha reforming process) were converted at 220-280 °C, 30-40 bar, 0. 8-3 1/h liquid hourly space velocity with hydrogen/hydrocarbon mole ratio 1:1-2:1. On the investigated catalysts beside significant skeletal isomerization of n-hexane practically the total amount of benzene was hydrogenated under favourable conditions determined by the kinetics and thermodynamic equilibrium of transformations. Most of the products are excellent gasoline blending components free of benzene.
