FORMATION COMPOSED OF MIXED OXIDES BY PYROLYSIS AND USE THEREOF

摘要

PURPOSE: Is provided mixed oxides-based formation by pyrolysis which has improved purity, excellent chemical and mechanical properties for a catalyst or a supported-catalyst for hydration of ethylene and propylene CONSTITUTION: The mixed oxides-based formation is obtained by the following steps: mixing the mixed oxides comprising at least two compounds selected from SiO2, Al2O3, TiO2 and ZrO2 to at least one compound selected from methyl cellulose, methyl hydroxy ethyl cellulose, wax, polyethylene glycol, magnesium stearate and aluminum stearate by adding water for being homogenize; drying the above oxides at 70-150°C; powdering mixed-oxides by milling, followed by press molding; being heat treatment at 400-1200°C for 0.5-10hrs.
