Acid Hydrolysis of Pretreated Palm Oil Lignocellulosic Wastes

Recalcitrant carbohydrates after enzymatic hydrolysis of pretreated lignocellulosic biomass

BACKGROUND To reduce the cost of the enzymes for the hydrolysis of lignocellulosic biomass, two main strategies have been followed: one, the reduction of enzyme dosing by the use of more efficient and stable enzymatic cocktails; another, to include accessory enzymes in the cocktails to increase yields by reducing the recalcitrant carbohydrate fraction remaining at the end of the process. To gui...

The Oil Palm Wastes in Malaysia

Palm Oil Mill Wastes Utilization; Sustainability in the Malaysian Context

Palm oil contributes about 19% of worldwide vegetable oil production with Malaysia accounting for over 50% of total production. Due to the global rise in crude oil prices, scientists have been forced to look for cheaper alternatives and palm oil has provided the right platform. This in turn led to an increase in the oil plantations and production in countries such as Malaysia, Indonesia and Tha...

Effect of Acid Hydrolysis and Thermal Hydrolysis on Solubility and Properties of Oil Palm Empty Fruit Bunch Fiber Cellulose Hydrogel

Cellulose hydrogel was produced from pretreated oil palm empty fruit bunch fiber (EFB) that went through acid hydrolysis and thermal hydrolysis. The pretreated EFB was dissolved in LiOH/urea aqueous solution using the rapid dissolution method and was subjected to a crosslinking process with the aid of epichlorohydrin to form hydrogel. The effects of both hydrolyses’ time on average molecular we...

Kinetic Modelling of Dilute Acid Hydrolysis of Lignocellulosic Biomass

Reviving the Acid Hydrolysis Process of Lignocellulosic Material in Biorefinery

The acid hydrolysis of lignocellulosic material (LM) is one of the most widely studied and important subprocess in the LM biorefinery. After acid hydrolysis, LM can be converted to various biofuels, biochemicals, and biomaterials through chemical or biochemical methods. However, conventional LM acid hydrolysis is not regarded as a cost-effective and environmentally-friendly process because it h...
