摘要: 在固定床加氢试验装置上考察了费-托蜡异构加氢裂化催化剂的温度敏感性以及氨浓度对催化剂温度敏感性的影响。结果表明,在常规的无氨操作条件下,催化剂表现出较强的温度敏感性。反应系统注入氨后,对催化剂活性有明显的抑制作用,但同时可以显著改善催化剂的温度敏感性。氨的引入并不改变转化率和选择性的对应关系,对液体产品性质也无影响,可以有效降低因温度波动给工业装置运行稳定性带来的不利影响。

Abstract: The effect of ammonia concentration on the temperature sensibility of isomerization-hydrocracking catalyst for F-T synthetic wax was studied in pilot plant. The results indicate that the catalyst exhibits a strong temperature sensibility in the case of NH3-free. The activity of catalyst is remarkably restrained by NH3 addition, meanwhile the temperature sensibility of catalyst is improved significantly. Neither changes in the relationship of conversion and selectivity nor the properties of liquid product occur after adding ammonia, except the reduction of influence of temperature fluctuation on stable operation of the unit.

Key words: F-T synthetic wax, isomerization-hydrocracking, NH3, temperature sensibility
