Problems solved by technology

Even if the polycyclic aromatic hydrocarbons developed by these two processes can meet the requirements of the European Union, due to the low content of aromatics and poor compatibility with rubber, they cannot be used as substitutes for rubber filler oils

Embodiment 1

[0029] Experiments were carried out on a small pilot rig. The hydrogenation reactor is a 100ml fixed-bed hydrogenation reactor; the fractional distillation uses a real boiling point distillation device with 17 theoretical trays. The raw oils were mineral oil, mineral oil and vegetable oil (1:1), mineral oil and vegetable oil (3:1), mineral oil and vegetable oil (6:1). A 100ml fixed-bed hydrogenation reactor is filled with a Mo-Ni-P hydrogenation catalyst supported on an amorphous aluminum silicate steroid, and its MoO 3 Accounting for 20w% of the total weight of the catalyst, NiO accounts for 9.2w% of the total weight of the catalyst, P 2 o 5 It accounts for 2.9w% of the total weight of the catalyst, and the rest is amorphous aluminum silicate steroid. The catalyst has a pore volume of 0.38ml / g and a specific surface area of ​​363m 2 / g, spherical. The catalyst is presulfurized by conventional methods before use, and the process condition inspection test is carried out af...

Embodiment 2

[0038] Except that the reaction conditions in the extraction tower were: temperature 70° C., the mass ratio of the solvent to the above reaction product was 3:1, and the extraction time was 1.5 h, the method was carried out according to Example 1. See Table 2 for the properties of the product obtained in Example 2.

[0041] Pour point °C

[0042] As can be seen from Table 2, the obtained biological rubber tire filling oil density of embodiment 2 is 910-950kg / m 3 , Viscosity at 40°C is 200-230mm 2 ·s -1 , the sulfur content is less than 300μg / g, C A If the value is 15-20%, PCA<2.3%, each main index meets the quality index requirements of environmental protection tire oil, good stability, non-toxic and tasteless.

Abstract

The invention mainly provides a production method of environmental protection biologic rubber tire filling oil, which uses the technologies of hydrogenation, extraction, fractionation in a combination way and provides a new idea for preparing the rubber filling oil by using mineral oil and vegetable oil together as raw material oil. A conventional device in traditional processing industry can be used. The production method has mature technology, simple production process and lower cost. The produced environmental protection rubber filling oil not only enables the environmental protection performance of an oil product to achieve European Union requirements, but also has good compatibility with rubber, and various main indicators all meet the quality indicator requirement of environmental protection tire oil.

Description

technical field [0001] The invention relates to the technical field of rubber additives, in particular to a production method of environment-friendly bio-rubber tire filling oil, which is used for filling and processing of various rubbers. Background technique [0002] Rubber extender oil is a special oil used in the production of oil-extended rubber. After the rubber is filled with oil, the processability and use performance can be improved, and at the same time, the output of rubber can be increased and the cost can be reduced. The output of natural rubber in my country is limited, and synthetic rubber occupies a large proportion in the rubber industry. With the advancement of my country's synthetic rubber technology and the increase in output, the output of oil-extended rubber is also increasing rapidly, so the demand for rubber-extended oil is also increasing day by day. [0003] However, polycyclic aromatic hydrocarbons (PCA) such as anthracene and phenanthrene contai...
