研究了轻烃芳构化 Ｚｎ Ｎｉ／ Ｈ Ｚ Ｓ Ｍ － ５ 催化剂的失 活类型， 认为积炭失活是改性 Ｚ Ｓ Ｍ － ５ 催化剂的最主要失活方式，经烧焦可恢复其催化活性。通过马弗炉 静态烧焦和反应管动态烧 焦， 考察了再生温度对烧焦过程的影响，推测出再生模式。在小型连续式１００ ｍ Ｌ 固定床装置上在宏观热效应方面模拟了工业烧焦再生过程，认为烧焦是一个从外向内逐步扩散的过程，在催化剂上会形成热点，在烧焦再生的影响因素（ 再生气的氧含量、空速，再生最高温度和时间等） 中，再 生最高温度的影响是最显 著的， 只有达到５７５ ℃才能恢复催化剂活性；而再生气空速和氧含量决定了再生时间。在所考察的３ 种再生方案中，确定了最佳的再生方案（ 低起燃温度，一次烧焦） 。该方案不仅比以往 方案省时５０ ％ ，而且 再生后 Ｚｎ Ｎｉ／ Ｈ Ｚ Ｓ Ｍ－ ５ 催化性能恢复好，稳定性不变。
The deactivation types of the light - aromatized Zn Ni / H ZS M - 5 catalyst were studied. It is believed that the deactivation of coke is the most important deactivation mode of the modified ZS M - 5 catalyst. active. Through the static scorching of muffle furnace and dynamic scorching of reaction tube, the influence of regeneration temperature on scorch process was investigated, and the regeneration mode was deduced. In a small continuous 100 m L fixed-bed unit, the process of industrial scorch regeneration was simulated in terms of macroscopic thermal effects. It is believed that scorching is a process of gradual diffusion from the outside to the inside, and will form a hot spot on the catalyst. (Oxygen content of regeneration gas, space velocity, maximum temperature and time of regeneration, etc.), the effect of regeneration maximum temperature is the most significant, and the catalyst activity can be restored only after the temperature reaches 575 ° C. The regeneration gas space velocity and oxygen content determine the regeneration time . Among the three regeneration schemes examined, the best regeneration scheme was determined (low ignition temperature, once burning). The scheme not only saves 50% of the time of the previous scheme, but also restores the catalytic performance of Zn Ni / H Z S M-5 after regeneration, and its stability is unchanged.
