中间基基础油生产优质高黏度白油技术的工业应用

白油加氢专用催化剂RLF-20具有良好的芳烃饱和性能，以中国石化荆门分公司100 kt/a白油加氢装置为例，以中间基减四线蜡油经糠醛精制-加氢处理-酮苯脱蜡得到的基础油为原料油，采用RLF-20催化剂对其进行深度加氢精制处理。结果表明：在氢分压为15.1 MPa、反应温度为236 ℃、体积空速为0.5 h^-1的条件下，所生产的运动黏度（100 ℃）为11.06 mm²/s的白油产品，能够满足国家标准GB 1886.215—2016规定的5号食品级白油的指标要求，并且产品收率高。

COMMERCIAL APPLICATION OF THE TECHNOLOGY FOR PRODUCING HIGH-QUALITY AND HIGH-VISCOSITY WHITE OIL FROM INTERMEDIATE BASE OIL

White oil hydrogenation catalyst RLF-20 has great aromatic saturation performance.SINOPEC Jingmen Company used heavy VGO of intermediate-base crude pretreated by furfural refining,hydrotreating,and ketone-benzol dewaxing to produce white oil with RLF-20 catalyst in a 100 kt a white oil hydrogenation unit.The results showed that under the conditions of a H 2 partial pressure of 15.1 MPa,a temperature of 236℃,and a LHSV of 0.5 h^-1,the obtained white oil with a kinematic viscosity(100℃)of 11.06 mm 2 s could meet the requiremeut of food grade white oil by GB 1886.215—2016 standard,and the product yield was high.
