SEB-08催化剂在干气制乙苯装置的工业应用

SEB-08 Catalyst Industry Application in Catalytic Dry Gas to EB Plant

烷基化催化剂SEB-08在中海油东方石化有限责任公司120 kt/a干气制乙苯装置的应用情况。该催化剂在开工过程中不需要活化,开工容易。此外,该催化剂还具有较高的活性与稳定性,主要体现在该催化剂反应起始温度低,再生周期较长。催化剂在该装置的运行结果表明,控制反应干气中丙烯含量低于300 mg/kg,严格控制循环苯中非芳和甲苯含量处于较低水平,乙苯产品中二甲苯含量、苯耗等都处在较低水平,表明该催化剂具备良好的选择性。

Alkrylation catalyst SEB-08 is used in the 120kt/a catalytic dry gas production of ethylbenzene in CNOOC Co., Ltd. The catalyst is not activated during the start up, and the start up is easy. In addition, the catalyst also has much higher activity and stability, which is mainly reflected in the low starting reaction temperature of the catalyst and a longer regeneration period. The operation results of the catalyst shows that the control of reaction gas and propylene content less than 300 mg/kg, and strictly control the low level in the non aromatic benzene and toluene content in recycle benzene, thus xylene content in ethylbenzene, benzene consumption is in much lower level, indicating that the catalyst has good selectivity.
