| 摘 要： | 在高压微反装置上，以苯乙烯为反应模型化合物，建立了气相色谱内标法定量分析裂解汽油-段加氢催化剂活性的方法，研究了RY-1催化剂对苯乙烯的加氢活性和对含硫、氮原料的加氢活性。结果表明：RY-1催化剂加氢效果好于进口催化剂L，但在纯烃加氢反应中单独抗硫和同时抗硫、氮中毒性能较差，单独抗氮性能较好；钙使催化剂的纯苯乙烯的加氢活性降低．而Y的加入提高了催化剂的加氢活性。

| Abstract: | The activity determination method of hydrogenated catalyst for pyrolysis gasoline in first stage hydrogenation section was established by gas chromatography internal standard quantitative in high pressure micro-reactor, styrene as the reaction model, then catalyst activity of RY-1 to styrene hydrogenated, and sulfur, nitrogen in the materials influence to the activity investigated. The results show that the RY-1 is superior to import catalyst of L in hydrogenated effects, however the ability of anti-poisoning in hydrogenated reaction to pure hydrocarbon is hypofunction for nitrogen/sulfur or sulfur, but better performance of anti-nitrogen. Calcium can destroy activity of the catalyst in hydrogenation of pure styrene, but the activity improved with Y added in the catalyst. |
