CN1990833A discloses a method of using naphthenic oil as a raw material to produce transformer oil in series through hydrotreating-hydrofining. This method does not improve the freezing point, and it is necessary to select suitable raw materials to obtain ideal products
CN201811291424.2 introduces a naphthenic distillate oil as raw material, using a two-stage serial hydrogenation process of hydrogenation-isomerization decondensation-deep supplementary refining to produce naphthenic special oil. This method has no requirement for pour point Separation of low light white oil, the space velocity of isomerization dewaxing and supplementary refining is relatively low, it needs to install more expensive precious metal catalysts, and the liquid recovery and target product yield are not high enough

Abstract

The invention discloses a method for producing naphthenic rubber filling oil through hydrogenation. Oil generated by hydrotreatment of naphthenic base vacuum distillate oil is used as a raw material and firstly enters a hydrofinishing reaction zone; fractionating the reaction product to separate out a light white oil product; all or part of the obtained heavy components enter an isodewaxing reaction zone for a hydroisomerization reaction; a hydroisomerization reaction product and raw materials enter a hydrofinishing reaction zone together for a deep finishing reaction. According to the method disclosed by the invention, the high-quality naphthenic rubber filling oil product can be obtained under the condition of less loading of the finishing catalyst, meanwhile, the high-quality special oil product is produced as a byproduct, the process is simple, and the operation energy consumption is low.

Description

technical field [0001] The invention relates to a method for producing naphthenic rubber filler oil by hydrogenation. Specifically, it is a method for producing naphthenic special oil products by using naphthenic vacuum distillate hydrotreating oil as raw material, through isomerization dewaxing / supplementary refining reverse sequence series process. Background technique [0002] Naphthenic crude oil has the characteristics of high density, high viscosity, low wax content, high aromatic and naphthenic content, and low freezing point. Refrigeration oil, rubber filler oil, etc. The traditional production of lubricating base oil is by solvent process. The two main steps are solvent refining to remove non-ideal components such as aromatics, and solvent dewaxing to ensure the low temperature flow properties of the base oil. Nowadays, the technology of producing lubricating oil by hydroprocessing is developing very rapidly. Hydroprocessing refers to the process of producing lubr...
