在实验室小型固定床装置上，采用Ａ、Ｂ、Ｃ３种吸附剂进行了焦化蜡油吸附脱碱氮研究。分别考察了反应温度、空速对吸附剂的脱碱氮效果的影响。结果表明，采用吸附剂可以有效脱出焦化蜡油中的碱性氮，且反应温度和空速对焦化蜡油的吸附脱碱性氮均有较显著的影响。３种吸附剂中，Ａ吸附剂的吸性性能最好。在常压、反应温度为８０℃、空速为０．５～１．０ｈ－１操作条件下，将焦化蜡油中的碱氮含量由１０５０μｇ／ｇ降到９５０μｇ／ｇ时，每毫升吸附剂可处理３００～４２０ｍＬ焦化蜡油。
A small fixed bed laboratory equipment, the use of A, B, C3 adsorbent for the study of coker gas oil adsorption and denitration. The effects of reaction temperature and space velocity on the desalting effect of adsorbent were investigated respectively. The results show that the adsorbent can effectively remove the basic nitrogen in coker gas oil, and the reaction temperature and space velocity have a significant effect on the adsorption and desalination of coker gas oil. Among the three kinds of adsorbents, A adsorbent has the best absorption performance. Under atmospheric pressure, the reaction temperature is 80 ℃, the space velocity is 0.5 ~ 1.0h-1 operating conditions, the coker gas oil in the nitrogen content from 1050μg / g down to 950μg / g per ml of adsorbent Can handle 300 ~ 420mL coker wax oil.
