新负载型碳三液相加氢催化剂的开发和工业应用

开发新负载型碳三馏分选择加氢催化剂，针对液相加氢工艺特点，在侧线装置上摸索和测试各种操控及运行参数，指导并首次成功应用于770kt/a乙烯装置。通过对催化剂的机械强度、催化性能以及操作窗口考察和研究，发现新型BC-L-83G催化剂的耐磨损、抗破碎以及长周期运行能力都大大优于上一代BC-L-83催化剂，并具有良好的温度适应性和氢炔比敏感度。工业应用的12个月试验结果表明，BC-L-83G具有催化活性高、选择性好、抗波动能力强、再生周期长等优势，非常适合进一步推广使用。

Development and industry application of new supported catalyst for C3 fraction liquid phase hydrogenation

The new supported selective hydrogenation catalyst for C₃ fraction was developed and successfully applied in the 770kt/a ethylene plant. Its various operation parameters and mechanical strength were tested on the side line unit according to the characteristics of the liquid phase hydrogenation process. It was found that the new catalyst of BC-L-83G was obvious superior to the previous BC-L-83 on the wear and crush resistances and the long-term running ability, with wide operation temperature range and excellent sensitivity to the molar ratio of H₂/MAPD. The 12-month running results of industrial application indicated that the BC-L-83G had the advantages of high catalytic activity, good selectivity, strong fluctuant resistance and long regeneration cycle, which is worth for further commercial applications.
