Abstract
This study describes the influence of torrefied coconut shell (CS) as solid fuel on pyrolysis product yield. The CS were torrefied and then pyrolysed in a fixed-bed reactor at different temperature and reaction time. The raw and torrefied CS were analysed for mass and energy yield, proximate analysis and ultimate analysis. The pyrolysis products yield were compared between raw CS and torrefied CS. The results showed that the properties of torrefied CS in terms of proximate and ultimate analysis were enhanced than raw CS. The calorific value for torrefied CS increased 17.17 MJ/kg to 22.25 MJ/kg. The optimum condition obtained for torrefaction pretreatment was at 275 °C and reaction time of 60 min. The highest bio-oil yield of 45% from pyrolysis process was at temperature and reaction time of 500 °C and 6 min, respectively. Thus, these results indicate torrefied CS was a suitable fuel feedstock to conduct in thermal conversion such as pyrolysis.
