I need to use zeolite for synthesis of fine chemicals, so which will make value added products and it will gives better reaction.
Kindly follow this link (http://www.sciencedirect.com/science/bookseries/00652113/113) and the chapter 4, you may get some clues for your question

Zeolite is a perfect catalyst. What is your intended process?
For example, Mordenite zeolite is good for isomerization, Y zeolite for hydrocracking, ZSM-5 and NaY for FCC proces
Dear Prof. Ramesh,
Can you please send me a copy of your chapter, I have no access to Elsevier!
Sepehr Sadighi . Thank you very much sir. My intention is FCC, but during exp I got X zeolite only. Do you have any Idea regards this ?
Zeolite have many classification acording to their metal composition, pore structure, dimension and pore sizes. In general, They can be used as size extrue agents through their unique pore size, as acid/base catalyst through silica and alumina center of zeolite frame, or as metal catalyst through metal deposite on zeolite frame. Zeolites have been found many applications in petroleum refining. As in FCC, ZSM-5 and Y Zeolite usually use as cracking catalyst for max.production of gasoline acording to their acidity, pore structure and pore size. Because they can be loaded with different metal, they can also be use as metal catalyst accomplished with size selectivity which especially for synthesis of fine chemicals.
There are many helpful textbooks and publications you may found in website.
Dear Siva, Zeolite X is not suitable to be used as a catalyst. Zeoilte X is a perfect adsorber. As a FCC catalyst, you need NaY or ZSM-5. I suppose that you should work on crystallization condition and SiO2/Al2O3 ratio.
ZSM-5 zeolite is a very good catalyst for this kind of reaction, it contains pore diameter about 25 A, an interesting surface area, but also must control the Si / Al ratio.
you can increase the surface of the ZSM-5 by different methods (see the references)

Zeolite suitable for catalytic conversion & of fine chemicals . It is green catalyst . e,g.
Conversion of m-xylene to 1,3-dicyanobenzene by ammoxidation reaction zeolite is used as a catalyst.
Dear siva, X zeolite is not good enough for FCC process. by changing crystallization condition, you can produce Y ZEOLITE. I will try to find for you a procedure to do that
Dear Mani,
Yes zeolite and alumina are the most common solid acid catalysts and they are being used in many industries due to their high surface area, mechanically stable and the porous structure; alumina mesoporous and zeolite microporous
Please find the attached paper that discussed the comparison between alumina and zeolite catalyst in dimethyl ether (biofuel) production.
Have a good day
Ahmed
