Isomerization reaction generally takes place over bifunctional metal \acid catalysts . Pure siliceous SBA- 15 and AISBA -15 of different nsi \nA1 ratios (5, 7 and 14) were synthesized by well - known procedures and used supports for preparation of Ni and Pt catalysts with different percentage UR - http://172.23.153.220/th.pdf ER -
