中文摘要：制备了3种不同ZSM-5分子筛含量的临氢降凝催化剂，对其孔道结构、酸性位和酸性强度进行了表征，并考察了3种催化剂在4种不同反应温度下临氢降凝所得产物的馏分分布以及基础油馏分的黏温特性和倾点变化，确定了最适宜用于废润滑油临氢降凝的催化剂为Z-2，反应温度为360℃。
英文摘要：Three kinds of hydro-dewaxing catalysts with different ZSM-5 molecular sieve content were prepared, and pore structure, surface acid type and strength of the catalysts were characterized. Then fraction distribution of hydro-dewaxing product, viscosity temperature characteristics and pour point of base oil were evaluated by three catalysts at four different temperature, the results showed that the appropriate catalyst was Z-2 and the optimal reaction temperature was 360℃.
