Methane, Hydrothermal pretreatment, Batch digestion, Oil palm fiber


This research aimed to study the effect of temperature (100-200C for 1 hrs) in hydrothermal pretreatment on the potential of methane production from oil palm fiber. The results showed that the optimum temperature in hydrothermal pretreatment to enhance the potential methane from the palm fiber was 140C due to small content of pseudo lignin formation (29.07%) and remaining hydrolyzed form of hemicellulose (13.56%). This pretreatment temperature provided the highest potential methane of 101.45+3.18 LCH4/kgVS which accounted by 43.89% higher than that of untreated palm fiber. Thus, the conversion of the oil palm fiber to biofuel as methane with low temperature hydrothermal pretreatment was suggested.
