摘要: 采用磷元素对载体进行改性,以等体积浸渍法制备了煤油芳烃饱和催化剂,并用BET、XRD、H2-程序升温还原、漫反射紫外可见光谱手段对催化剂进行表征。考察了不同反应温度、反应压力下的催化剂芳烃饱和活性,并与未改性催化剂和参比剂进行了对比。结果表明:反应压力为6.0 MPa左右较为适宜,调整反应温度是装置工艺条件优化的主要手段,磷改性后催化剂的芳烃饱和活性与未改性催化剂及参比剂相比有明显的提高。

Abstract: The carrier was modified by phosphorus followed by preparation of aromatic saturation catalyst for kerosene by incipient impregnation of Ni-W solution. The catalysts were characterized by BET, XRD, H2-temperature programmed reduction, diffuse reflectance ultraviolet-visible spectra techniques. The aromatic saturation activities under different reaction temperatures and reaction pressures were investigated. The results show that the appropriate reaction pressure is 6.0 MPa, and adjusting reaction temperature is the main means for optimizing the process conditions. Compared with unmodified catalyst and reference catalyst, the phosphorus modified catalysts have a significant higher aromatic saturation activity.

Key words: kerosene, aromatic saturation, catalyst
