SUBMERGED PROPYLENE HYDRATION MICRO-INTERFACE STRENGTHENING REACTION SYSTEM AND METHOD THEREOF
A submerged propylene hydration micro-interface strengthening reaction system and a method are proposed. The system includes a reactor, a first micro-interface generator and a second micro-interface generator. Through the micro-interface generators, the propylene is broken to form micron-scale bubbles, which are mixed with reactants and deionized water to form a gas-liquid emulsion, so as to increase a phase boundary area between gas and liquid phases, and achieve a strengthening mass transfer effect under a lower preset operating condition. The micro-scale bubbles can be fully mixed with the deionized water to from a gas-liquid emulsion. By fully mixing gas and liquid phases, it can ensure that the deionized water in the system is in full contact with propylene, and they are fully in contact with the catalyst, which effectively improves the efficiency of preparing isopropanol.
