| Abstract: | Abstract A 20 litre packed bed reactor (PBR) with heating and water removal system was designed and fabricated for the
esterification of palm oil fatty acid distillate (PFAD) catalyzed by immobilized rice bran lipase (RBL). The PBR was designed
based on the characteristics of immobilised RBL and the optimized esterification conditions obtained from method scouting
performed in shaked flask. The optimal ratios of immobilised RBL and water removal agent (silica gel) to PFAD for the shaked flask
esterification process were 5:1 and 1:2, respectively. The intensified esterification reaction of PBR was operated by circulating the
reaction mixture (PFAD and glycerol) in hexane through a packed bed column filled with immobilised RBL. The water generated
from esterification reaction was absorbed by silica gel filled in the water removal vessel. The maximum degree of esterification
achieved in this developed PBR was 61%. The reaction time required to achieve the maximum degree of esterification was 25%
faster than that in the shaked flask. |
