Abstract: The invention discloses a rotating packed bed reactor for enzyme catalysis and an application method of the reactor in fatty acid production through enzyme catalysis lipid hydrolysis. The method comprises the steps that lipid and water are adopted as raw materials to be mixed with lipase for a catalysis reaction, the catalysis reaction is conducted under the condition that the supergravity level (gravitational acceleration) is 5 g to 120 g, steel mesh packing is adopted, the substrate flow speed is 80 mL/min to 120 mL/min, the temperature is 35 DEG C to 55 DEG C, the lipase adding amount (lipase/substrates) is 0.5 wt% to 1.5 wt%, and the lipid-water mass ratio is (0.5-1.5):1, free fatty acid is prepared after reacting is conducted for 8 hours to 24 hours, and the hydrolysis yield can reach 98%. According to the method, lipase is used for catalytically producing the fatty acid in the rotating packed bed reactor for the first time, and the advantages that a rotating packed bed is high in mass transfer intensity and mass transfer efficiency, and the materials are full in micromixing in the bed and short in dwell time are achieved in a lipase catalysis technology; in a solvent-free system, compared with a traditional stirring system, the technology has the advantages that the reaction time is shortened by 30%-50%, and the fatty acid yield is increased by 15% to 50%. | |
