Solid Acid Catalyst From Biedillite Intercalated by mixed cohydrolysis (Ti-Zr)Improve their acidity and stability thermic.

Abstract

Clays of smectite type have long been used as adsorbent material (1) , intercalated clays are anew class of calalyst . in which an homogeneous distribution of microspores can be obtained with porosity varying from 6 Aº to 18 Aº according to the type of intercalating agents.The activity catalytic and adsorbents were attracted the tension to this type of clay .R.M Barrer (2) prepared expanded clay which act as molecular sieves for the adsorption of organic molecules from the uses of Tetraalkyl ammonium as intercalating agent with clay.
