Title: Influence of Ni, Mg and P on Selectivity of Zsm-5 Class Zeolite Catalysts in Toluene-Methanol Alkylation and Methanol Conversion
Abstract: Physicochemical and catalytic properties of ZSM-5 zeolites modified with nickel, magnesium and phosphorus have been studied. Conversion of methanol and alkylation of toluene with methanol were used as test reactions. Measurements of sorption capacity of argon, water, cyclohexane, para- and ortho-xylene revealed plugging of channels and modication of hydrophilicity due to impregnation. Introduction of phosphorus blocked all strong acid centers, whereas Ni and Mg had only little effect on their distribution. Unmodified HZSM-5 and Ni/HZSM-5 gave near-equilibrium composition of xylene isomers, whereas with P/HZSM-5 95-100% of para-isomer was formed. Introduction of nickel resulted in considerable increase of the content of aromatics in methanol conversion.
