Low-Temperature Dilute Acid Hydrolysis of Oil Palm Frond
Oil palm frond (OPF) fiber, a lignocellulosic waste from the palm oil industry, contains high cellulose and hemicellulose content, thus it is a potential feedstock for simple sugars production. This paper describes the two-stage hydrolysis process focusing on the use of low-temperature dilute acid...

| description | Oil palm frond (OPF) fiber, a lignocellulosic waste from the palm oil industry, contains high cellulose and hemicellulose content,
thus it is a potential feedstock for simple sugars production. This paper describes the two-stage hydrolysis process focusing on the
use of low-temperature dilute acid hydrolysis to convert the hemicellulose in OPF fiber to simple sugars (xylose, arabinose, and
glucose). The objective of the present study was to evaluate the effect of operating conditions of dilute sulfuric acid hydrolysis
undertaken in a 1 L self-built batch reactor on xylose production from OPF fiber. The reaction conditions were temperatures
(100–140�C), acid concentrations (2–6%), and reaction times (30–240 min). The mass ratio of solid=liquid was kept at 1:30. Analysis
of the three main sugars glucose, xylose, and arabinose were determined using high-pressure liquid chromatography. The optimum
reaction temperature, reaction time, and acid concentration were found to be 120�C, 120 min, and 2% acid, respectively. Based on
the potential amount of xylose (10.8 mg=mL), 94% conversion (10.15mg=mL) was obtained under the optimum conditions with
small amount of furfural (0.016 mg=mL). To enhance the effectiveness of dilute acid hydrolysis, the hydrolysis of OPF fiber was
also performed using ultrasonic-pretreated OPF fiber. The effects of ultrasonic parameters power (40–80%) and ultrasonication
times (20–60 min) were determined on sugar yields under optimum hydrolysis conditions (2% acid sulfuric, 120�C and 120 min).
However, the use of ultrasonication was found to have detrimental effect on the yield of simple sugars due to the 10-fold increase
in the formation of furfural. |
