Abstract

Abstract: ZSM-5 samples were prepared by alkali treatment under different conditions. The acidity and pore structure o f ZSM-5 had significant effect on n-hexane isomerization performance of P t/ZSM-5. The increase in strong acid sites led to an enhancement in n- hexane conversion. The creation of mesopores was favorable for the formation of dimethyl butane.

Key words: platinum, ZSM-5, alkali treatment, acidity, pore structure, n-hexane, isomerization
