Catalytic MFI zeolite membranes supported on α-Al2O3 substrates for m-xylene isomerization

► We prepare H-MFI catalytic membranes by H+ ion-exchange on MFI/α-Al2O3 membranes. ► H-MFI membranes have bi-function of xylene isomerization and separation. ► H-MFI membranes show very high p-xylene selectivity for xylene isomerization.
