国产贵金属芳烃饱和催化剂生产不同黏度食品级白油技术的开发及工业应用

DEVELOPMENT AND INDUSTRIAL APPLICATION OF DOMESTIC NOBLE METAL AROMATICS SATURATION CATALYST FOR VARIOUS VISCOSITIES FOOD GRADE WHITE OIL PRODUCTION

中国石油克拉玛依石化公司的50kt/a白油加氢装置采用中国石化石油化工科学研究院开发的贵金属白油加氢催化剂,在反应压力17.5MPa、反应温度216～237℃、空速0.3h-1条件下,以克拉玛依石化公司润滑油高压加氢装置生产的润滑油基础油为原料,生产的低黏度产品质量符合国家标准GB 4853—1994的规格要求,高黏度产品符合企业自定的食品级白油研制指标。

In this paper,the application of a noble metal aromatics saturation catalyst（developed by Research Institute of Petroleum Processing） in various viscosities food grade white oil production is introduced.At the 50 kt/a white oil hydrogenation plant of Karamay Petrochemical Company,using hydrogenated base oil from the lube oil high pressure hydrogenation unit as feedstock,under the conditions of a reaction pressure of 17.5 MPa,reaction temperature in the range of 216—237 ℃ and a space velocity of 0.3 h-1,the qualities of the low viscosity food grade white oil meet the requirements of National Standard GB 4853—1994,and the qualities of the high viscosity products meet the requirements of Company Standard for food grade white oil.
