Problems solved by technology

[0005] However, all of these technologies do not involve the environmental protection treatment of the extracted polycyclic aromatic oil, and this part of the oil is more harmful to the environment than the high aromatic oil before extraction due to the enrichment of polycyclic aromatic hydrocarbons. If this part of PAH oil cannot be treated in an environmentally friendly manner, in a certain sense, the production process of TDAE is not environmentally friendly.
Although traditional treatment methods can be adopted for this part of PAH oil, such as transferring it to high-aromatic oil as a product output or entering a coking unit to generate coke, none of them can further increase the value, and there are environmental problems

Abstract

The invention relates to environment-friendly filling oil preparation method. The method comprises the following steps: performing hydrotreatment on polyaromatic hydrocarbon oil to obtain hydrotreatment oil; placing the hydrotreatment oil in an extracting tower for extracting a solvent, after the extraction is completed, a raffinate is obtained at the tower top of the extracting tower, the target product environment-friendly filling oil is obtained after the solvent is recovered, an extract is obtained at the tower bottom of the extracting tower, the extract oil is obtained after the solvent is recovered; the extract oil is subjected to hydrotreatment, and is placed at the extracting tower for solvent extracting, and the steps are repeated. The aromatic hydrocarbons content of the filling oil is high, the filling oil has good compatibility with the rubber, the processing property is excellent, while in use during a tire manufacture process, excellent performances such as good wet-skid resistance can be provided to the tire; the content of polyaromatic hydrocarbon compound in filling oil satisfies an EU export standard, wherein benzopyrene is undetected, so that the filling oil has no toxic and no carcinogenic effects.

Description

technical field [0001] The invention relates to a method for preparing an environmentally friendly extender oil, which is especially suitable for the process of hydrogenating high aromatic extract oil rich in polycyclic aromatic hydrocarbons to prepare the environmentally friendly extender oil. Background technique [0002] Since the European Union put forward the requirement of environmentally friendly filler oil, a lot of energy has been invested in research in this area at home and abroad, and some results have been obtained one after another. The difficulty of the research is that the environmentally friendly extender oil must not only meet the requirements for the content of polycyclic aromatic hydrocarbons, but also perfectly replace the original high-aromatic oil to meet the filling requirements of styrene-butadiene rubber. This puts forward higher requirements on the treatment process of environmentally friendly extender oil, and also puts forward higher requirements...
