摘要
以拟薄水铝石为原料,加入一定量的扩孔剂、金属助剂等,可制备改性氧化铝载体。采用浸渍法制备了钯/氧化铝催化剂。以裂解汽油C5～C9馏分为原料,在温度为60℃,压力为3.0 MPa的条件下,对催化剂的性能进行了评价。结果表明,改性后催化剂对杂质砷、水等有一定的耐受能力。
Modified alumina carrier was prepared by adding pore - expanding agent and metal assistant. The catalyst Pd/Al2O3 was prepared by the method of impregnation with a modified alumina carrier. The catalyst properties were evaluated with C5 - C9 fraction of pyrolysis gasoline as raw material, under the condition of temperature 60 ℃ , pressure 3. 0 MPa. The results showed that the water and arsenic resistances were enhanced.
