Problem Statement: The palm oil industry generates an abundance of oil palm biomass such as the mesocarp fibre, shell, empty fruit bunch (EFB), frond, trunk and palm oil mill effluent (POME). For 80 million tonnes of fresh fruit bunch (FFB) processed last year, the amount of oil palm biomass was more than 25 million tones. The objectives of this study were to: (i) Determine the effect of various pyrolysis parameters on product yields and (ii) Characterise liquid product obtained under different condition. Approach: In this study, pyrolysis of oil palm Empty Fruit Bunches (EFB) was investigated using quartz fluidized fixed bed reactor. The effects of pyrolysis temperatures, particle sizes and heating rates on the yield of the products were investigated. The temperature of pyrolysis and heating rate were varied in the range 300-700 °C and 10-100 °C min 1 respectively. The particle size was varied in the range of <90, 91-106, 107-125 and 126-250 µm. The elemental analysis and calorific value of the bio-oil were determined. The chemical composition of the oil was investigated using chromatographic and spectroscopic techniques. Results: Under the experimental conditions, the maximum bio-oil yield was 42.28% obtained at 500 ºC, with a heating rate of 100 ºC min

“…The sharp peak at 1,047 cm -1 was attributed to -C-O-Cstretching vibrations of polysaccharides or from the bending vibration of -C-OH. The peak near 874 cm -1 was characteristic of C-H bending vibration in a b-glucosidic linkage (Ozcimen and Karaosmanoglu 2004). Another band was found at about 800 cm -1 , which was expected to be associated with the out-of-plane bending mode of O-H.…”

Magnesium hydroxide-coated pyrolytic biochar composite was prepared by chemical precipitation, and the adsorption behavior of anionic dye (directly frozen yellow) onto magnesium hydroxide-coated pyrolytic biochar was investigated in the batch mode. The Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy and X-ray fluorescence spectroscopy of adsorbents were characterized. Adsorption studies were performed at different pH, salt concentration, contacting time and dye concentration. The pH value of the solution influenced the adsorption capacity significantly, and adsorption is favored of pH 6-8. Salt coexisted in solution increased slightly directly frozen yellow adsorption capacity. The isotherm data were analyzed by Langmuir and Freundlich isotherm model, and Langmuir model was better to predict the equilibrium data. Thermodynamic calculations showed that the adsorption was a spontaneous and endothermic process. Exhausted magnesium hydroxide-coated pyrolytic bio-char was treated by microwave irradiation, and yield of regeneration was 98 % in the case of microwave irradiated time 5 min at 320 W. The magnesium hydroxide-coated pyrolytic bio-char can be reused.

“…It was reported that more than 120 compunds which were mainly oxygenated organics such as acids, aldehydes, ketones, esters and phenols were identified [7]. Rapeseed (Brassica napus L.Oleifare) cake was pyrolyzed in a fixed-bed reactor [8]. The highest bio-oil yield of 59.7 % was obtained at final pyrolysis temperature of 500 o C under static temperature.…”

Abstract. The production of crude palm oil from the processing of palm fresh fruit bunches in the palm oil mills in Malaysia hs resulted in a huge quantity of empty fruit bunch (EFB) accumulated. The EFB was used as a feedstock in the pyrolysis process using a fixed-bed reactor in the present study. The optimization of process parameters such as pyrolysis temperature (factor A), biomass particle size (factor B) and holding time (factor C) were investigated through Central Composite Design (CCD) using Stat-Ease Design Expert software version 7 with bio-oil yield considered as the response. Twenty experimental runs were conducted. The results were completely analyzed by Analysis of Variance (ANOVA). The model was statistically significant. All factors studied were significant with p-values < 0.05. The pyrolysis temperature (factor A) was considered as the most significant parameter because its F-value of 116.29 was the highest. The value of R 2 was 0.9564 which indicated that the selected factors and its levels showed high correlation to the production of bio-oil from EFB pyrolysis process. A quadratic model equation was developed and employed to predict the highest theoretical bio-oil yield. The maximum bio-oil yield of 46.2 % was achieved at pyrolysis temperature of 442.15 o C using the EFB particle size of 866 μm which corresponded to the EFB particle size in the range of 710-1000 μm and holding time of 483 seconds.
