摘要
本文介绍了引进装置配套裂解汽油加氢所用的第二段催化剂８６０２Ｂ的性能，并与该装置用过的Ｇ－３５Ｂ催化剂作了比较。在入口温度３００℃（比Ｇ－３５Ｂ低２９℃）、压力２．８ＭＰａ，液时空速２．８ｈ－１、氢：油为１．５：１（摩尔比）工况条件下，通过在扬子石化公司烯烃厂７０３２ｈ连续工业运转考核，产品加氢率为９９％（Ｇ－３５Ｂ为９６～９８％）、脱硫率为９９．９％（Ｇ－３５Ｂ为９６．７％），说明其性能优良，是替代Ｇ－３５Ｂ、用于第二段加氢脱硫的理想催化剂。
The performance of catalyst 86o2B for the second-stage hydrodesulfurization of pyrolysis gasoline is presented and is compared with the imported catalyst G--35B which was used before. This catalyst has been in continuous operation for 7032 hours in the define plate of Lanzhou Chemical industry Corporation. Under the operation conditions of 300 ℃ inlet temperature (29 ℃ lower than G--35B), 2. 8 MPa pressure, 2. 8 h -1 space velocity and 1. 5: 1 H2/oil mole ratio, the rate of hydrogenation is 99% (comparing to 96-98% for G-35B) and the rate of desulfurization is 99. 9% (comparing to 96. 7% for G-35B). It is concluded that 8602B is excellent in performance and is an ideal alternative for G--35B as the secondstage hydrodesulfurization catalyst for pyrolysis gasoline.
