The pillared montmorillonite has been prepared by exchanging
Na+ in the interlayer of montmorillonite with Al hydroxy cation followed
by calcination. Pillared clays are also prepared after exchanging
Na' ions with Ce, La, Sm-ions and then pillarcd with aluminium
oxides, The surface characterisation of the prepared catalysts has been
done using XRD and surface area measurements. To probe the acidic
property of the system, temperature programmed desorption (TPD)
of NH, has been done. Toluene alkylation by benzyl chloride has
been carried out for the evaluation of catalytic activity. The most
active system is found to be mixed Al/Zr pillarcd montrnorillonite. |
