DOWNWARD FIXED-BED ENHANCED REACTION SYSTEM WITH OIL HYDROGENATION MICRO INTERFACE

摘要

A downward fixed-bed enhanced reaction system with an oil hydrogenation micro interface, comprising a fixed-bed reactor (4) and a micro interface generator, wherein the micro-interface generator is arranged on the upper part of the fixed-bed reactor (4) and converts the pressure energy of hydrogen and/or the kinetic energy of oil during reaction into surface energy of bubbles and transmits the same to hydrogen bubbles, so that the hydrogen is broken into micro bubbles, and the micro-bubbles are mixed with the oil in the reaction process to form a gas-liquid emulsion; the fixed-bed reactor (4) is used as a reaction site for hydrogenation to form a stable gas-liquid enhanced fixed-bed reaction system when the gas-liquid emulsion enters therein; a gas-liquid separation tank (5) is connected to the fixed-bed reactor (4) and is used for gas-liquid separation of the mixture that completes reaction in the fixed-bed reactor (4).
