Problems solved by technology

[0003] An important step in the treatment process of reformed oil is the hydrogenation reaction, but the hydrogen mixing equipment used in the prior art has an unsatisfactory mixing effect, and the hydrogen can only be dispersed into milli-centimeter-scale bubbles in the oil, and Only about 50% of the hydrogen can be dissolved into the reformed oil, resulting in a small gas-liquid interface area and uneven distribution, resulting in low gas-liquid mass transfer rate and hydrogenation reaction rate, resulting in low olefin hydrogenation saturation depth , resulting in a high bromine index in the product oil

Embodiment 1

[0043] refer to figure 1 As shown, it is a reformed oil microinterface hydrogenation device according to an embodiment of the present invention, which mainly includes a hydrogenation reactor 5, and a pneumatic microinterface generator 9 is arranged in the center of the lower part of the hydrogenation reactor 5, and the hydrogenation reaction The bottom of the device 5 is provided with a material pipeline for conveying the reformed oil, and a microinterface unit 6 is arranged on the material pipeline. In this embodiment, three pneumatic microinterface generators 9 are connected in parallel to form a microinterface unit 6 . Both the pneumatic micro-interface generator 9 and the micro-interface unit 6 play the role of dispersing and crushing hydrogen, but one is inside and the other is outside, and the two cooperate with each other to achieve the best effect of crushing hydrogen.

[0044] The micro-interface unit 6 is also connected to a hydrogen filter 4 with a filtration accura...

Embodiment 2

[0056] Other operation steps are the same as in Example 1, except that the temperature at the inlet of the reactor is set at 100° C., and the pressure at the inlet of the reactor is set at 1.2 MPa.

[0057] Analytical Results: Bromine Index = 850, Aromatics Loss = 0.23%.

Embodiment 3

[0059] Other operation steps are the same as in Example 1, except that the temperature at the inlet of the reactor is set at 180° C., and the pressure at the inlet of the reactor is set at 2.0 MPa.

[0060] Analytical Results: Bromine Index = 820, Aromatics Loss = 0.27%.

Abstract

The invention provides a micro-interface hydrogenation device and method for reformate. The micro-interface hydrogenation device for the reformate comprises a hydrogenation reactor, a material channel for conveying reformate is arranged at the bottom of the hydrogenation reactor, a pneumatic micro-interface generator for dispersing and crushing hydrogen is arranged inside the hydrogenation reactor, and a micro-interface unit for dispersing and crushing hydrogen is arranged outside the hydrogenation reactor; the pneumatic micro-interface generator is arranged in the center of the lower part in the hydrogenation reactor, and the micro-interface unit is arranged on the material channel. By using the device and the method, the bromine index of the product oil can be effectively reduced, the aromatic hydrocarbon loss is avoided, and the reaction temperature and pressure are reduced to a certain extent.

Description

technical field [0001] The invention relates to the field of petroleum processing, in particular to a micro-interface hydrogenation device and method for reformed oil. Background technique [0002] Reformed oil is an important intermediate product in the petroleum processing industry, and various aromatic hydrocarbons rich in it can be used in various industries such as rubber industry, shoemaking industry, pharmaceutical industry, pesticides, adhesives, etc. In addition, high-octane gasoline can be prepared by removing components below carbon 5 from the reformed oil. [0003] An important step in the treatment process of reformed oil is the hydrogenation reaction, but the hydrogen mixing equipment used in the prior art has an unsatisfactory mixing effect, and the hydrogen can only be dispersed into milli-centimeter-scale bubbles in the oil, and Only about 50% of the hydrogen can be dissolved into the reformed oil, resulting in a small gas-liquid interface area and uneven d...
