Abstract: To fill the domestic blank in the area of high-viscosity food-graded white oil, PetroChina Karamay Petrochemical Co Ltd used heavy distillate as raw material and adopted the four-stage high-pressure hydrogenation process for production of No. 4 high-viscosity foodgraded white oil. The product meets the requirements of GB1886. 215- 2016 thanks to its small evaporating loss, appropriate carbon structure and viscosity and good photostability and thermal stability, reaching the quality level of its foreign counterparts. This paper introduces the production process and compares the Chinese and foreign standards and the performances of the products of the same kind. It also analyzes the application cases in polystyrene production.
