摘要: 对C5抽余油与非芳烃汽油混合加氢制备蒸汽裂解料技术的工艺条件进行了研究,考察工艺条件对转化率的影响。得出适宜的工艺条件为:稀释进料,C5抽余油/非芳烃汽油体积比(1:5)~(1:7)、平均反应温度120~140 ℃、压力4.0~5.0 MPa、体积空速1.0~4.0 h-1、氢油体积比200~400。在此条件下加氢后反应产物中二烯烃质量分数不大于0.1%。1 500 h的稳定性试验结果表明,该催化剂具有良好的活性和稳定性。

Abstract: The process for the selectively hydrogenation of C5 raffinate oil mixed with non-aromatic gasoline was tested. The effect of reaction conditions such as the feed dilution ratio, reaction temperature,reaction pressure, liquid hourly space velocity(LHSV) and volume ratio of hydrogen to oil were investigated. The optimized conditions are: ratio of C5 raffinate oil/non aromatic gasoline(1:5)-(1:7), the average temperature 120-140 ℃,reaction pressure 4.0-5.0 MPa , LHSV 1.0-4.0 h-1,volume ratio of hydrogen to oil 200-400. Under these conditions, the diolefins in the product were less than 0.1%. The long run experiment proves that the catalyst has a good performance in activity and stability.
