Embodiment 1

[0021] Tested on a small test rig. The hydrogenation reactor of the device is a 100ml fixed-bed hydrogenation reactor, and the fractionation tower is a true boiling point distillation device with 17 theoretical trays. The coal tar fraction processed in the test is coal tar (phenol, naphthalene and tar pitch have been separated) produced by an industrial coal dry distillation unit, and its main properties are shown in Table 1. The 100ml fixed-bed hydrogenation reactor is filled with amorphous Mo-Ni-P hydrogenation modification catalyst on aluminum silicate support, its MoO 3 content of 22.8w%, NiO content of 3.4w%, P 2 o 5 The content is 4.8w%, and the rest is amorphous aluminum silicate carrier. The catalyst has a pore volume of 0.38ml / g and a specific surface area of ​​363m 2 / g, the shape is spherical, and the diameter is φ2.0mm. The catalyst is presulfurized by a conventional presulfurization process before use, and after the activity of the catalyst is stable, the pro...

Embodiment 2

[0027] According to Example 1, the difference is the hydro-upgrading process conditions and the component content and physical parameters of the Mo-Ni-P hydro-upgrading catalyst. See Table 2 for the process conditions of hydrogenation upgrading and the product properties of fractions above 360°C. The MoO of the Mo-Ni-P hydrogenation upgrading catalyst used 3 content of 20.5w%, NiO content of 4.6w%, P 2 o 5 The content is 5.9w%, and the rest is amorphous aluminum silicate carrier. The catalyst has a pore volume of 0.40ml / g and a specific surface area of ​​375m 2 / g, the shape is spherical, and the diameter is φ2.5mm.

[0028] The used test apparatus of embodiment 2, coal tar fraction, processing steps and other unillustrated operation process, all are identical with embodiment 1.

[0029] It can be seen from Table 2 that the sulfur content of the aromatic hydrocarbon type rubber extender oil obtained in Example 2 is 352 μg / g, the nitrogen content is 786 μg / g, the aromatic ...

Embodiment 3

[0031] According to Example 1, the difference is the hydro-upgrading process conditions and the component content and physical parameters of the Mo-Ni-P hydro-upgrading catalyst. See Table 2 for the process conditions of hydrogenation upgrading and the product properties of fractions above 360°C. The MoO of the Mo-Ni-P hydrogenation upgrading catalyst used 3 content of 18.1w%, NiO content of 5.4w%, P 2 o 5 The content is 6.8w%, and the rest is amorphous aluminum silicate carrier. The catalyst has a pore volume of 0.42ml / g and a specific surface area of ​​388m 2 / g, the shape is spherical, and the diameter is φ2.8mm.

[0032] The test apparatus used in embodiment 3, the coal tar fraction, the processing steps and other undescribed operating procedures are all the same as in embodiment 1.

[0033] It can be seen from Table 2 that the sulfur content of the aromatic hydrocarbon type rubber extender oil obtained in Example 3 is 375 μg / g, the nitrogen content is 844 μg / g, the a...

Abstract

A process for preparing the arylhydrocarbon-type filling oil for rubber includes such steps as mixing tar fraction with H2, hydrogenating reaction on hydromodifying catalyst Mo-Ni-P for removing S, N, colloid and asphalt from tar fraction, separating out H2, dry gas, H2S, NH4 and liquefied gas to obtain liquid, fractionating, and cutting.

Description

technical field [0001] The invention belongs to the field of coal chemical industry and relates to a production method of aromatic hydrocarbon type rubber filler oil. 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, while increasing the output of rubber and reducing the cost. 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 extender oil is also increasing day by day; among them, aromatic hydrocarbon-type rubber extender oil has good compatibility with various types of rubber and is full of energy. The amount of oil is large, so the amount is also the largest. [0...
