摘　　要：以加氢尾油为原料，在FS-J1固定床催化反应器上利用自制的FL-J型非临氢降凝催化剂进行中试实验。在温度为340～400℃，空速为2-5h。的条件下，考察了催化剂的使用性能，以及产品分布和产品质量。结果表明，在常压、非临氢反应条件下，当温度为400℃、空速为2h^-1时，得到较好的产品分布，柴油的凝点为-29℃，润滑油的凝点为-16℃。，催化荆运转4，5×10^3h进行水蒸气气提，能使催化剂活性部分得到恢复，反应温度可降低20℃左右。FL-J型非临氢降凝催化刘具有良好的应用前景。Using hydrocracking tail oil as feed stock, the pilot -scale experiment was done on FS J1 fixed catalytic bed reaction apparatus with self made FL - J non- hydro dewaxing catalyst. The catalytic performance, production distribution and product property were studied under the temperature of 340 - 400℃ and space velocity of 2 - 5 h^-1 The results show that production distribution is good, the solidification point of diesel fuel reaches 29℃ , and the solidification point of lubricating oil reaches 16 ℃; when reaction temperature is 400℃, reaction space velocily is 2 h^-1 at normal pressure and without hydrogen. The catalysts are treated by steam after 4.5 × 10^3 hours, the activity of catalyst is partly reactivated, the reaction temperature is reduced about 20 ℃,. FL-J non-hydro-dewaxing catalyst has good application foreground.
