Problems solved by technology

[0002] The pyrolysis oil produced by cracking hydrocarbons to produce ethylene is used in the production of petroleum resins to produce aromatic solvent oils. This solvent oil has a strong odor, dark color, high content of unsaturated hydrocarbons, and a certain amount of dicyclopentadiene and styrene. As a result, solvent oil is very easy to polymerize, which seriously affects its quality and limits its application range

Abstract

A hydrofining method of aromatic solvent naphtha is characterized by that its makes the aromatic solvent naphtha which possesses heavy abnormal smell and dark colour and is richly produced in the course of producing petroleum resin by using pyrolytic oil undergo the two-stage hydrofining treatment to obtain the solvent naphtha meeting the product quality requirements for paint industry. This invented method is simple in process, its operation is easy to control, it does not produce polymerization reaction, and its whole hydrogenation process can be normally implemented.

Description

technical field [0001] The invention relates to a method for hydrogenation treatment of hydrocarbon oil, more specifically, a method for hydrogenation refinement of aromatics-rich solvent oil in the process of producing petroleum resin from cracked oil produced by cracking hydrocarbons to produce ethylene. Background technique [0002] The pyrolysis oil produced by cracking hydrocarbons to produce ethylene is used in the production of petroleum resins to produce aromatic solvent oils. This solvent oil has a strong odor, dark color, high content of unsaturated hydrocarbons, and a certain amount of dicyclopentadiene and styrene. Cause mineral spirits to polymerize very easily, have a strong impact on its quality, limit its scope of application. [0003] Solvent oil is used in many fields, mainly as fuel, and partly used in the paint industry, but paint has certain requirements on the quality of solvent oil. The quality of the above-mentioned production of petroleum resin-rich ...
