Abstract

Abstract:

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 ℃.

Key words: Catalytic dewaxing , Hydrocracking tail oil , Catalyst , , Lube base oil

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%。
