Cracking and isomerization functionalities of bi-metallic zeolites for naphtha value upgradation

► Cr ion-exchange on H-BEA followed by Pt impregnation resulted in creation of moderate acid sites. ► Cr in H-BEA acts as Pt receptor to facilitate improvement in dispersion and reducibility of Pt sites. ► Cr promotes isomerization by reducing cracking activity of acid sites and hydrogenolysis activity of Pt. ► The Pt-Cr-HBEA is suitable for octane boosting of various hydrocarbon feedstocks.
