高鋁硅鋁有許多独特的优点,如活性、稳定性、强度等較高,应更适用于頁岩油及重残油的裂化,因此目前国外已开始工业化試制和应用。混合法制备的高鋁硅鋁,虽然在方法上比較成熟,但制备流程較复杂,不能連續操作,均匀性也較差。共胶法硅鋁具有胶体均勻度較好、鋁的利用率高、强度和重复性好、且有可能成球形等为混合 High alumina aluminosilicate has many unique advantages, such as high activity, stability, strength and so on, should be more suitable for the cracking of shale oil and heavy residual oil, so the current foreign countries have begun trial production and application. Although the method is relatively mature, the preparation process is complicated and can not be operated continuously and the uniformity is poor. Co-Glue Silica has better colloidal uniformity, high utilization of aluminum, strength and repeatability, and may be spherical, etc. for the mixed
