Micro-interface enhanced hydrogenation reaction system

Abstract

The invention provides a micro-interface enhanced hydrogenation reaction system. The system comprises: a reactor main body used as a reaction chamber in a hydrogenation reaction process so as to ensure that the hydrogenation reaction can be fully carried out; and a micro-interface generator, wherein the micro-interface generator is connected with the reactor main body, the micro-interface generator is used for crushing hydrogen and/or liquid-phase reactants into micro-bubbles and/or a solid-liquid mixed material with micron-sized diameters in the micro-interface generator through a mechanicalmicrostructure and/or a turbulence microstructure in a preset action manner before the hydrogen and the liquid and/or solid-liquid mixed material enter the reactor main body in the hydrogenation reaction process, so the mass transfer efficiency between reaction phases is improved, and the reaction hydrogenation reaction is enhanced under the conditions of preset temperature and pressure. The system effectively solves the problem that the mass transfer rate is affected due to the fact that the phase boundary contact area of a reaction phase is small in the using process of an existing reactionstrengthening system.

Description

technical field [0001] The invention belongs to the technical field of reaction strengthening, and in particular relates to a micro-interface strengthening hydrogenation reaction system. Background technique [0002] Gas-liquid, gas-liquid-solid and other gas-liquid reaction processes are widely found in energy, petrochemical, fine chemical and other fields. For gas-liquid heterogeneous reactions such as oxidation, hydrogenation, and chlorination, the macroscopic reaction rate is generally limited by the mass transfer process. The volumetric mass transfer coefficient of gas-liquid reaction is mainly affected by the mass transfer coefficient and the gas-liquid interface area. Previous studies have shown that the phase boundary area has a greater influence on the volumetric mass transfer coefficient and is easy to control. Therefore, increasing the phase boundary area is regarded as an effective way to increase the gas-liquid macroscopic reaction rate. [0003] Bubble react...
