The objective of this contribution was to examine the possibility of using colloidal silica as a binder for the preparation of extrudates or pellets from mesoporous molecular sieves. Al- SBA-15 pellets with different content of colloidal silica were prepared and their textural properties and mechanical stability were investigated. The catalytic activity of the pellets in Friedel-Crafts alkylation of toluene with benzyl alcohol was directly compared to that of binder-free pellets and powder catalyst.
