GAS-LIQUID-SOLID THREE-PHASE REACTOR AND USE THEREOF

摘要

A gas-liquid-solid three-phase reactor, comprising a reactor cylinder (1) with a catalyst support disc (2), a gas-liquid dispensing disc (4) and a liquid distributing pipe (3) provided inside the cylinder (1) in succession from bottom to top along the cylinder (1), wherein the catalyst support disc (2), the liquid distributing pipe (3) and the gas-liquid dispensing disc (4) are arranged radially along the cylinder (1); the gas-liquid dispensing disc (4) has a plate-like structure, provided with holes extending through the top and bottom surfaces of the plate; the liquid distributing pipe (3) has a hollow tubular structure, the surface of the pipe being provided with small holes extending through the inner and outer surfaces of the pipe body, the liquid distributing pipe (3) being connected with a lateral feed port (9) provided on the side wall face of the cylinder (1); the side wall face of the cylinder (1) above the catalyst support disc (2) is provided with a catalyst discharge port (11); and a top feed port (8) is provided at the top of the cylinder (1) and a bottom discharge port (10) is provided at the bottom of the cylinder (1). The reactor is suitable for a gas-liquid-solid three-phase reaction at a temperature of 0 - 400°C, and a pressure of 0 - 30.0 MPa, and can be used in the reaction for preparing ethylenediamine with ethanolamine and ammonia as raw materials in the presence of hydrogen.
