A Kinetic Study on Acid Hydrolysis of Oil Palm Empty Fruit Bunch Fibers Using a Microwave Reactor System

Oil palm empty fruit bunch is a lignocellulosic material from palm oil plantations. It is a potential source of xylose which can be used as a raw material for production of xylitol. Using of lignocellulosic waste for bioconversion to fuels and chemicals is justifiable as these materials are low cost, renewable and widespread sources of sugars. The objective of the present study was to determine the effect of H2SO4 concentration, reaction temperature and reaction time for acid hydrolysis of pretreated OPEFB, pretreated OPEFB with reaction temperature, reaction time and NaOH concentration were 130 °C, 40 min and 15% (w/v), respectively to achieve high xylose yield. Batch reactions were carried out under various reaction temperature, reaction time and H2SO4 concentration. Response Surface Methodology (RSM) was followed to optimize acid hydrolysis in order to obtain high yield of xylose. The optimum reaction temperature, reaction time and H2SO4 concentration were found to be 140 °C, 90 min and 7% (w/v), respectively. The maximum value of xylose was obtained 56.39 g/l by using the above condition. The best result of xylose yield obtained was 126%.

Hydrolysis Of

The decomposition of tryptophan in aqueous HC1 at 100�C has been shown to proceed by a free-radical autoxidation mechanism. The acid functions by protonating the amino acid at either the 1- or 3-positions prior to autoxidation and so 1-methyltryptophan is also decomposed under these conditions. Impurities present in the soda glass containers used are shown to be responsible for the initiation of the reaction. The decomposition of tryptophan during the acid hydrolysis of proteins is considered in the light of these results.
