Problems solved by technology

Due to the high content of sulfur and nitrogen, high metal content, and aromatics accounting for more than 50% of catalytic oil slurry, its application is limited. Except for a small amount of raw materials used in other secondary processing processes, most of them are burned as fuel oil, which not only wastes resources , causing environmental pollution

Abstract

The invention discloses a method for producing a special oil product by using catalytic slurry oil as a raw material. The catalytic slurry oil is firstly refined by a solvent; raffinate oil is mixed with hydrogen, and the mixture is sequentially in contact with a protective agent, a hydrofining agent and a hydro-upgrading agent for hydrogenation reaction; separating a hydro-upgrading effluent, and enabling an obtained liquid-phase product to enter a fractionating tower; enabling diesel oil fractions obtained through fractionation to enter a pour point depressing reaction zone, using a single-stage hydrocracking catalyst in a hydrogenation pour point depressing reaction zone, and conducting hydrogenation modification and isomerization reaction in the presence of hydrogen; and carrying out hydrofinishing reaction on the hydrodewaxed effluent, and separating the hydrofinishing product to obtain large-specific-gravity aviation kerosene, transformer oil base oil and refrigerating machine oil base oil. The processing method for improving the economical efficiency of the catalytic slurry oil is provided for the catalytic slurry oil with low additional value.

Description

technical field [0001] The invention relates to a production method of naphthenic special oil products, in particular to a catalytic oil slurry using solvent refining-hydroprocessing (hydrofining / hydrogenation upgrading) / hydrogenation decondensation-hydrogenation replenishment A method for producing high specific gravity aviation kerosene, transformer oil base oil and refrigerating machine oil base oil by refining two-stage combined process. Background technique [0002] Naphthenic crude oil is a scarce resource, and its reserves only account for 2.2% of the world's proven oil reserves. It is recognized as a high-quality resource for the production of electrical insulating oil and rubber oil. Naphthenic oil has the characteristics of strong solvency, good heat transfer, high viscosity and good low temperature performance, and is recommended for three main applications: transformer oil for the electrical industry, rubber filler oil and metal processing oil and grease.
