在国外石油工业上已开始采用的高铝硅铝裂化催化剂具有良好的抗热性、机械强度和活性,这些优点也应适用于页岩油的裂化.研究此种催化剂的活性中心性质,无论在学术上或实用上都是有意义的.本工作则从较易掌握的混合法着手,制备及试验不同铝含量的硅铝,然后进一步研究其他裂法与性质.(一)制备方法及裂化性能:催化剂的制法是先将氧化硅与氧化铝分别成胶(简称硅胶与铝胶)及洗涤,然后按重量比用球
The aluminosilicate cracking catalysts that have been used in foreign petroleum industry have good heat resistance, mechanical strength and activity, and these advantages should also be applied to the cracking of shale oil.Research on the active center nature of this catalyst, Both academic and practical.Starting from the easier to understand mixing method, this work prepares and tests aluminosilicates with different aluminum contents, and then further studies on other cracking methods and properties. (1) Preparation method and cracking performance : Preparation of the catalyst is the first silica and alumina gel (referred to as silica gel and aluminum glue) and washing, and then by weight ball
