用于焦化苯气相乙基化制乙苯的耐硫工业催化剂
摘要：
本发明涉及用于焦化苯气相乙基化制乙苯的耐硫工业催化剂及其制备方法。该催化剂是由纳米HZSM-5沸石分子筛、α·Al2O3、金属或非金属氧化物改性剂组成；其制备方法是采用晶粒尺寸在20～200纳米的HZSM-5沸石分子筛催化剂经过高温水蒸气处理或高温氨水蒸气处理和湿法浸渍负载II B族元素锌的氧化物、IIIB元素镧的氧化物、VIB元素钼的氧化物、VIII元素钴和镍元素氧化物、碱金属元素镁氧化物、非金属元素磷氧化物分别或组合改性而成；具有用于含硫量200～800ppm的焦化苯气相乙基化反应，不需脱硫工序，催化剂再生周期为60天等优点。
摘要（英）：

The present invention relates to industrial sulfur tolerant catalyst for vapor ethylation of coking benzene to prepare ethyl benzene and its preparation process. The catalyst consists of nanometer HZSM-5 zeolite molecular sieve, alpha-Al2O3, and metal or non-metal oxide as modifier. Its preparation process includes high temperature water vapor or ammonia water vapor treatment of 20-200 nm crystal grain size HZSM-5 zeolite molecular sieve catalyst; and soaking the molecular sieve catalyst to support oxide of IIB element zinc, oxide of IIIB element La, oxide of VIB element Microwave oven and/oroxide one non-metal element P for modification. It may be used in the vapor ethylation of coking benzene with sulfur content of 200-800 preparation directly without needing desulfurizing and with the catalyst regenerating period as long as 60 days and other advantages.
