Method of manufacturing acetic acid

摘要

PROBLEM TO BE SOLVED: To provide a method for carrying out a reaction at a high catalyst concentration in the method for producing acetic acid according to a heterogeneous catalyst reaction using a bubble tower type reactor.

SOLUTION: This method for producing the acetic acid comprises carbonylating methanol with CO (carbon monoxide) according to the heterogeneous catalyst reaction using the bubble tower type reactor. In the method, the solid catalyst concentration is ≥100 kg/m3based on a reaction volume and the CO partial pressure in the reactor is within the range of 1.0-2.5 MPa. The discharge ratio of the CO is 3-15% based on a theoretical amount of reaction and the liquid superficial speed is 0.2-1.0 m/s.
