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 for 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 environment-friendly rubber filling oil base oil through hydrogenation of catalytic slurry oil. The method comprises the following steps: fractionating the catalytic slurry oil so as to obtain a light fraction and a heavy fraction and allowing the light fraction to be mixed with hydrogen, then enter a hydrotreating reaction zone and successively contact with a hydrogenation protection catalyst, a hydrorefining catalyst and a hydroupgrading catalyst A for hydrogenation; allowing hydrogenation effluent to enter a hydroupgrading reaction zone where a hydroupgrading catalyst B containing amorphous silicon aluminum and modified Y zeolite and an after-refining catalyst are used, carrying out hydroupgrading reaction in the presence of hydrogen and saturating olefin produced in the process of hydroupgrading at the lower part of the hydroupgrading reaction zone; and separating hydroupgrading products so as to obtain environment-friendly rubber filling oil. The method provided by the invention uses the catalytic slurry oil as a raw material and can produce the environment-friendly rubber filling oil with good low-temperature fluidity, intersolubility with rubber, oxidation stability, safety and environmental protection property.

Description

technical field [0001] The invention relates to a production method of an environment-friendly rubber filler oil, specifically a method for producing an environment-friendly rubber filler oil by adopting a hydrogenation treatment-hydrogenation modification stage series hydrogenation method using catalytic oil slurry pretreated by raw materials method. Background technique [0002] Rubber filler oil plays an important role as an auxiliary agent in the rubber industry. It can improve the plasticity of the rubber, reduce the viscosity of the rubber and the temperature during mixing, and can promote the dispersion and mixing of other ingredients. Extrusion acts as a lubricant and reduces the hardness of vulcanized rubber and improves its properties. Rubber filler oil can also increase rubber output, reduce costs, improve rubber processing performance and performance, and plays an important role in the rubber processing industry. [0003] As a rubber extender oil with the large...
