The effect of AI, Fe, and in substitution in the MFI silicate structure on the aromatic hydrocarbon transformation: SiOHM site strength

The conversion of toluene in toluene disproportionation and its alkylation with ethylene over metallosilicates (AI, Fe, In) of the MFI structure has been found to be proportional to the concentration of the individual framework bridging SiOHM groups, and when related to one SiOHM site, it increases in the sequence of the isomorphous substitution of Si for In < Fe
