Problems solved by technology

To sum up, the existing technology of producing food-grade white oil from vacuum distillate oil, solvent-refined deasphalted oil and Fischer-Tropsch synthetic oil requires at least three stages of hydrogenation to solve the problems of product pour point and aromatics content process, so the process is more complicated and the cost is higher

Abstract

The present invention provides one-section hydrogenation process for producing food level white oil. By using vacuum gas oil, deasphalted solvent oil and Fischer-Tropsch process oil as material, and hydrogenating catalyst containing modified beta-molecular sieve in 1-9 wt%, and through hydrocracking or hydrogenating, hot high pressure separating out gas and light distillate to obtain liquid product, mixing with newly formed hydrogen, and high pressure hydro-finishing in a reactor with loaded reduction type hydrogenating catalyst, food level white oil is produced. The process is simple and hashigh product quality.

Description

technical field The invention relates to a method for producing food-grade white oil, specifically a method for producing food-grade white oil by a one-stage hydrogenation process. Background technique White oil is a type of petroleum product obtained by deep refining of lubricating oil fractions to remove impurities such as aromatics and sulfides in lubricating oil fractions. It is colorless, odorless and stable in chemical properties, and is widely used in chemical industry, daily necessities, food, medicine, textile and agriculture and other fields. According to different uses and refining depths, white oil can be divided into industrial, cosmetic, food and pharmaceutical categories. Among them, food-grade white oil is the most refined. The white oil production process is mainly the process of removing sulfur, nitrogen, aromatics and other impurities from the base oil. The production process of white oil mainly includes: old three methods, sulfonation method and hydro...
