文摘

A set of K-exchanged X zeolites with different exchange degree were prepared and investigated in the alkylation of toluene with methanol. The chemical composition, textural properties, crystalline phase and acid-base properties of catalysts were analyzed by ICP, N₂ physisorption, XRD, NH₃-TPD and XPS. Experimental results demonstrated that the direction to ring or side-chain alkylation depended on the K exchange degree (K_ED) greatly.
