摘要
以茂名石化加氢裂化尾油为原料,使用NKC-7型催化降凝催化剂,在固定床催化降凝装置上进行实验。在温度为340～400℃、空速为1～8h-1的条件下,考察了反应温度、空速对产品分布、凝点、收率的影响。结果表明:当温度为380℃、空速为2h-1时,得到较好的产品分布,润滑油基础油的凝点为-24℃,收率为61.4%。
Lube base oil were produced by catalytic dewaxing from hydrocracking tail oil of the Mao Ming Petrochemical Corporation in fixed catalytic bed reactor using NKC--7 as the dewaxing catalyst. The effects of reaction temperature （340- 400℃） and space velocity（ 1-8 h^- 1） on the product distribution, solidifying point and liquid yield were studied. The results show that good product distribution and higher yield of lube base oil （61.4 % ） can be obtained at 380 ℃ and a space velocity of 2 h^-1 , the solidifying point of lube base oil can reach --24 ℃.
