Chemical Pretreatment Comparison for Oil Palm Empty Fruit Bunch: A Review

Abstract:

Lignocellulosic waste such as oil palm empty fruit bunch are becoming attractive research areas as it can be converted into biofuel or cellulose fiber. Pretreatment of lignocellulosic due to its complex structure is needed to enhance its digestibility during conversion to the required product.Lignin content and distribution is responsible for recalcitrance of lignocellulosic material, therefore delignification process can improve the rate and extent of enzymatic hydrolysis. Pretreatment of Oil Palm Empty Fruit Bunch (OPEFB) that mainly aim for delignification can be classified as biological, physical, chemical, and physical-chemical pretreatment. Most common chemical pretreatment of OPEFB are alkaline pretreatment, dilute acid pretreatment, and organosolv delignification. High efficiency of delignification can be achieved by combining several methods.
