<br/><br/> Nowadays isomerization of n- paraffins plays an important role in the petroleum industry . Isomerization reaction generally takes place over bifunctional metal \acid catalysts . Pure siliceous SBA- 15 and AISBA -15 of different nsi <br/>A1 ratios (5, 7 and 14) were synthesized by well - known procedures and used supports for preparation of Ni and Pt catalysts with different percentage
