| 摘 要： | 探讨了焦炉煤气加氢脱硫催化剂器外预硫化的方法,研究了硫化剂加入量以及预硫化浸渍温度、浸渍时间、浸渍压力等硫化条件对催化剂活性的影响,同时对预硫化催化剂的稳定性能进行考察。结果表明,以单质硫和有机多硫化物的混合物溶于馏分油中制成的混合硫化物作为硫化剂,在温度140℃和压力1. 0 MPa的条件下,将焦炉煤气加氢脱硫催化剂浸渍2 h所制备的器外预硫化型催化剂活性优于传统的器内预硫化的催化剂,且催化剂性能稳定。

| Abstract: | Methods for perparing ex-situ presulfurization for coke gas hydrodesulfurization catalysts were studied.Such factors as amount of sulfiding agent added,presulfurization impregnated temperature,impregnated time and impregnated pressure that impact catalyst acticity were investigated. The stability of presulfurization catalysts were also investigated.The research results show that with the mixture of sulfur and organic sulider dissolved in distillate oil made as sulfiding agent,under the condition of temperature is 140 ℃,pressure is 1.0 MPa,the coke gas hydrodesulfurization catalyst impregnated 2 h.The catalysts prepated by this method had more activity and stability than in-situ presulfurization catalysts. |
