一种含硫焦化液化气高温加氢催化剂及其制备方法和应用
摘要：
本发明涉及一种用于焦化液化气高温加氢饱和的催化剂及其制备方法和应用，催化剂以γ-氧化铝为载体，催化剂活性组分为钼、镍，以催化剂总重量100%计，含Mo2O310.0%~20.0%，NiO 6.0%~18.0%，催化剂为Ф3×3~5mm的条型、三叶草型或球型，比表面积100~200m2/g。在催化剂的制备过程中，先负载钼，再负载镍，经烘干、焙烧得到催化剂。本发明催化剂可用于焦化液化气、焦化剩余C4高温加氢饱和，催化剂不需进行预硫化，氢气气氛还原后可以直接用于焦化液化气、焦化剩余C4高温加氢，焦化液化气、焦化剩余C4不需要进行预处理。加氢反应进料温度180~230℃，反应温度280~300℃，反应压力2.3~3.5MPa，体积液时空速1.5~8.0h-1，氢/烯烃摩尔比1.2~1.8：1，加氢后烯烃含量均可小于1%。
摘要（英）：

The invention relates to a sulfur-containing coking liquefied gas high-temperature hydrogenation catalyst and its preparation method and use. The sulfur-containing coking liquefied gas high-temperature hydrogenation catalyst utilizes gamma-alumina as a carrier, comprises active components of 10.0 to 20.0% of Mo2O3 and 6.0 to 18.0% of NiO, is in a shape of a strip, a whitetip clover or a ball having the size of dia. 3*(3-5)mm and has a specific surface area of 100 to 200m<2>/g. The preparation method comprises the following steps of molybdenum loading, nickel loading, drying and calcination. The sulfur-containing coking liquefied gas high-temperature hydrogenation catalyst can be used for high-temperature hydrogenation saturation of coking liquefied gas and coking residual C4, avoids catalyst pre-vulcanization, can be directly used for high-temperature hydrogenation of coking liquefied gas and coking residual C4 after hydrogen atmosphere reduction, and avoids pre-treatment on coking liquefied gas and coking residual C4. A hydrogenation reaction feeding temperature is in a range of 180 to 230 DEG C; a reaction temperature is in a range of 280 to 300 DEG C; reaction pressure is in a range of 2.3 to 3.5MPa; a liquid hourly space velocity is in a range of 1.5 to 8.0h<-1>; a hydrogen/olefin mole ratio is (1.2 to 1.8): 1; and olefin content is less than 1% after hydrogenation.
