Calcination process was conducted in tube furnace at temperature of 900 °C for 1 hour for converting the calcium carbonate to CaO in the eggshell. Elemental composition, crystallite structures, and morphological structures were performed for characterization of eggshell while ultimate and proximate analysis, heating value, and thermogravimetric analysis was performed for characterization of biomass. Catalytic pyrolysis was conducted by different parameters such as temperature, heating rate, holding time and catalyst loading to study the effect of pyrolysis parameters on oil yield. Optimization was performed by Design Expert 7.1 Software. Oil yield were analyzed in order to determine the quality of oil. High oil yield were obtained at temperature of 400 °C, heating rate of 80 °C/min, holding time at 4 min and 10% of catalyst loading. For temperature parameter, oil yield was increased by 14%, while gas yield reduced by 13.7% and char yield reduced by 0.3%. For heating rate, oil and char yield was increased by 15.4% and 3.9%, respectively, while gas yield decreased by 19.3%. Meanwhile, for holding time parameter, the oil and gas yield was increased by 10.4% and 13.1%, respectively while char yield decreased by 23.5%. The oil and char yield increased by 14.7% and 9.6%, respectively after the addition of eggshell catalyst. However, gas yield reduced by 24.3%. Meanwhile, from optimization studied, high oil yield were obtained at temperature of 434.63 °C, heating rate of 76.03 °C/min, holding time at 2.55 min, and 8.02% of catalyst loading, with predicted bio-oil yield was 31.81%. Confirmation runs were performed by using the same conditions and gave an average of 31.41%. Analysis from FTIR and GCMS showed that most of oxygenated and nitrogen compound were reduced after the addition of catalyst such as carboxylic acids, amide, amines and ketones compound while hydrocarbon and phenols were increased. 2016 2021-10-08T00:56:20Z 2021-10-08T00:56:20Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/72325 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Environmental Engineering
