Abstract:
The objective of the present work is to improve the textural and structural
properties of zeolite-Y through ion exchange with rare earth metals. We meant to
obtain a comparative evaluation of the physicochemical properties and catalytic
activity of rare earth modified H-Y, Na-Y, K-Y, and Mg-Y zeolites. Friedel-Crafts
alkylations of benzene with higher 1- olefins such as 1-octene, 1-decene, and 1dodecene
for the synthesis of linear alkylbenzene (LAB) have been selected for the
present study. An attempt has also been directed towards the correlation of the
enhancement in 2-phenylalkane formation to the improvement in the textural and
structural properties upon rare earth modification for the zeolite-Y. The present
method for LAB synthesis stands as an effective Green alternative for the existing
hydrofluoric acid technology
