Monoliths washcoated with ZSM5 and metal oxide (MgO, CaO, La2O3 or CeO2) modified ZSM5 were prepared, characterized and studied for toluene disproportionation. An improvement in the yield of the desired p-xylene isomer was obtained by using monoliths coated with metal oxide-modified ZSM5. The enhancement in p-xylene yield depended on the type of modifier, metal loading and the washcoat thickness on the monolith. The 10% LaZSM5 coated monolith having an average washcoat thickness of 23 mu m showed the highest p-xylene yield.
