摘要
利用N2吸附法、IR酸性表征、微型和小型反应器等手段研究了改性高岭土基质催化剂的性能特点。结果表明,高岭土经过热和化学改性后形成了一定活性的中孔结构,添加这种新材料制成的FCC催化剂具有较强的抗重金属污染和重质油转化能力。
The properties of FCC catalyst employing acidmodified kaolin as matrix was investigated using N2 adsorption, IR acid characterization and microactivity and small reactor test. The results showed that certain reactive mesoporous structure was formed in kaolin modified by calcination and acid leaching. FCC catalyst containing modified kaolin exhibited good tolerance to metal contamination and excellent heavy oil cracking performance.
