The effects of preparation factors, such as organoamines, prelaminate, degree of hydrolysis and addition of Cr, on the structure and properties of chromium oxide layer-supported zirconium phosphate were studied in detail. The specific surface area of chromium oxide layer column prepared by ethylamine colloidal method can be as high as 482m2 / g, while the pore size concentrates around 26nm. Moderate hydrolysis of the surface phosphates during the colloidization of the lamellae facilitates the increase of the specific surface area of the lamellar product and the formation of a regular plate-type intercostal pore. The formation process and thermal stability of the chromia column were studied by TG, IR, XRD and N2 adsorption isotherms. Isopropyl alcohol dehydration and cumene pyrolysis reaction results show that the surface of chromium oxide layer zirconium phosphate contains strong acid sites or strong and weak acid sites co-exist. The chromium oxide layer column zirconium phosphate has higher catalytic activity for the dehydrogenation of cyclohexane and ethylbenzene than the supported catalyst Cr2O3 / SiO2.
