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 white rubber filling oil base oil through catalytic slurry oil hydrogenation. The method comprises the following steps: catalytic slurry oil is subjected to fractionation, such that a light fraction and a heavy fraction are obtained; the light fraction is mixed with hydrogen, and the mixture enters a hydrogenation treatment reaction zone; the mixture sequentially contacts a hydrogenation protection catalyst, a hydro-refining catalyst and a hydro-upgrading catalyst A, such that a hydrogenation reaction is carried out; a hydrogenation treatment effluent enters a hydro-upgrading reaction zone; a hydro-upgrading catalyst B containing amorphous silica-alumina and modified Y zeolite is adopted in the hydro-upgrading reaction zone, and a hydro-upgrading reaction is carried out under the existence of hydrogen; a hydro-upgrading effluent enters a hydro-finishing reaction zone, and is subjected to a hydro-finishing reaction; and a hydro-finishing product is separated, such that the rubber filling oil base oil is obtained. According to the invention, the catalytic slurry oil is adopted as a raw material, and can be used for producing the white rubber filling oil base oil with good low-temperature fluidity, good intersolubility with rubber, and good oxidation stability.

Description

technical field [0001] The present invention relates to a production method of rubber extension oil base oil, specifically a method for producing white rubber extension oil base oil by using hydrogenation treatment-hydrogenation modification-hydrogenation supplementary refining combined hydrogenation process method of catalytic oil slurry method. Background technique [0002] Naphthenic crude oil to produce rubber extension oil: In order to improve some properties of rubber, mineral oil needs to be filled into synthetic rubber, so it is called rubber extension oil. In synthetic rubber, the rubber chain structure usually contains benzene ring structure. According to the principle of similarity and mutual solubility, aromatic oil should be the ideal rubber oil, followed by naphthenic oil. However, because aromatic oil is a highly toxic substance, as people's calls for health, safety, and environmental protection are increasing day by day, and some high-end products such as sp...
