摘要: 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。

Abstract: 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 H2 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 mm2/s could meet the requirement of food grade white oil by GB/T 1886.215—2016 standard, and the product yield was high.
Key words: RLF-20 catalyst, hydrofining, high viscosity, white oil
