Embodiment 1

[0024] Embodiment 1, the preparation of environment-friendly rubber oil

[0025] The low-quality naphthenic heavy wax oil is obtained from the industrial unit of CNOOC (Qingdao) Heavy Oil Processing Engineering Technology Research Center Co., Ltd., and its properties are shown in Table 1. It can be seen from the data in Table 1 that the kinematic viscosity of the low-quality naphthenic heavy wax oil at 100 °C is 43.7mm 2 / s, the freezing point is 2°C, and has the characteristics of high kinematic viscosity and low freezing point; it can be seen from the structural group composition data that the total content of saturated hydrocarbons and aromatics is 83.0%, and the content of polar compounds and asphaltenes is very high, respectively. 16.4% and 0.6%.

[0026] Using low-quality naphthenic heavy wax oil as raw material (see Table 1 for detailed properties), in the propane deasphalting pilot plant (manufactured by Luoyang Kaimeisheng Petrochemical Equipment Co., Ltd., the feed ...

Embodiment 2

[0032] Embodiment 2, the preparation of environment-friendly rubber oil

[0033] The raw material oil, test device and preparation method used in Example 2 are exactly the same as those in Example 1, except that the operating conditions are different from those in Example 1. The detailed operating conditions and test results are shown in Table 2.

[0034] It can be seen from the data in Table 2 that the C of environmentally friendly rubber oil A The value is 14.6%, C N The value is 37.0%, C P The value was 48.4%, the content of polycyclic aromatic hydrocarbons was 1.4%, the content of PAHs was 1.5mg / kg, and the content of benzo[a]pyrene was not detected.

Embodiment 3

[0035] Embodiment 3, the preparation of environment-friendly rubber oil

[0036] The raw material oil used in embodiment 3, the test device and the preparation method are exactly the same as in embodiment 1, but the operating conditions are different from those in embodiment 1. The detailed operating conditions and test results are as shown in table 2; as can be seen from the data in table 2, environmentally friendly rubber oily C A The value is 15.1%, C N The value is 37.1%, C P The value is 47.8%, the content of polycyclic aromatic hydrocarbons is 1.5%, the content of PAHs is 1.7mg / kg, and the content of benzo[a]pyrene is not detected.

Abstract

The invention discloses an environmentally-friendly rubber oil and a preparation method thereof. The method comprises the following steps: 1, extracting inferior cycloalkyl heavy wax oil in a propane deasphalting extraction tower with propane to obtain a refined liquid at the top of the propane deasphalting extraction tower, and recovering a solvent to obtain refined heavy wax oil; and 2, carrying out solvent refinement of the refined heavy wax oil in an extraction tower to obtain an extract liquid at the bottom of the extraction tower and a refined liquid at the top of the extraction tower, recovering the solvent of the extract liquid to obtain extract oil, and recovering the solvent of the refined liquid to obtain the environmentally-friendly rubber oil. The method utilizing the inferior cycloalkyl heavy wax oil to prepare the environmentally-friendly rubber oil widens the raw material source of the environmentally-friendly rubber oil, satisfies the demands of the markets at home and abroad, and also greatly improves the added values of the inferior cycloalkyl heavy wax oil. The method has the advantages of small solvent ratio in the solvent refining process, low energy consumption and solvent consumption, and high target product yield.

Description

technical field [0001] The invention relates to a method for producing environment-friendly rubber oil from inferior cycloalkyl heavy wax oil and the prepared environment-friendly rubber oil, belonging to the field of petrochemical industry. Background technique [0002] Oils used in rubber synthesis or rubber processing are collectively referred to as rubber oil. As an important additive, rubber oil is widely used in the rubber industry. After the rubber is filled with oil, the processability and use performance are improved, while the output of rubber is increased and the cost is reduced. In recent years, the domestic tire industry has developed rapidly. China is a big tire manufacturing country, and tire oil has become the largest application field of rubber oil. More than one-third of domestic tires are exported overseas. [0003] The harm of traditional high-aromatic rubber oil to human health and the pollution to the environment have attracted great attention from go...
