Embodiment 1~5

[0022] Embodiment 1~5 (continuous operation)

[0023] The product is continuously extracted from the oil phase extraction port, cooled to room temperature, and then washed with water, alkali washed, washed with water, and adsorbed and desulfurized in order to remove the polar sulfides generated by oxidation (mainly thiophene compounds in diesel oil are Oxidation to generate corresponding sulfone compounds), sampling and analysis, the sulfur content in the oil sample was quantitatively analyzed by coulometric method. The reaction conditions and results are shown in Table 1. There is no vibration in the reactor during the whole reaction process, and the reaction pressure and temperature can be controlled smoothly.

Abstract

The invention discloses an impinging stream reactor, which comprises a reactor housing, a reaction impinging tank, and a liquid transfer pump. The reaction impinging tank is arranged in the reactor housing, the impinging tank is openmouthed, the guide cylinders are symmetrically arranged in the impinging tank, the guide cylinder is passed through a liquid feed line of the reactor housing and is connected to the liquid transfer pump, an air intake is arranged on a top cover of the reactor housing, a lower cover is a liquid holding tank with a taper structure, and an extraction port is arranged on the holding tank. In the impinging stream reactor, an oil phase extraction port, a water phase extraction port and a circulation solution extraction port are arranged on the holding tank, and are respectively arranged at an oil phase zone of the holding tank, a water phase zone and a tone top position of the holding tank. The temperature and pressure in the impinging stream reactor is easy to be controlled, the shocking of the reactor due to impinging reaction is reduced, and the impinging stream reactor is suitable for oil product oxidation desulphurization reaction.

Description

technical field [0001] The invention relates to an impingement flow reactor and its application, in particular to an impingement flow reactor suitable for oil oxidative desulfurization and its application. Background technique [0002] With the enhancement of human environmental awareness and the gradual improvement of environmental protection laws and regulations, the production of low-sulfur and ultra-low-sulfur gasoline and diesel is gradually attracting people's attention. Nitrogen, olefins, benzene and aromatics are limited, which requires the global oil refining industry to continuously improve and innovate existing processes and develop some advanced technologies to produce clean fuels. Therefore, the production of clean fuel is the development trend of the oil refining industry at present and even in the long term in the future. [0003] At present, gasoline and diesel desulfurization technologies are divided into hydrodesulfurization and non-hydrodesulfurization. H...
