Abstract
Thousand tonnes of oil palm trunk OPT will be produced annually in Malaysia. This has a significant effect on the environment particularly due to the green house gas GHG that are released during its decomposition. In this study OPT was pyrolysed at temperature which ranges from 200C to 600C with a heating rate of 10C/min. The char yield decreased rapidly with increasing pyrolysis temperature up to 300C. Above 300C the char yield decreased proportionately as the temperature increases. However the gas yield includes the loss of fine oil droplets showed the opposite trend it increases with increasing reactor temperature. The oil production showed the same trend as gases but the proportions are much lower. The highest percentage of oil produced was at 600C. At the temperature of 200C there was no significant effect on the distribution of the production of liquid char and gases. It may be because of insufficient energy to break down the larger molecules to smaller one. The study on the effect of particle size on products yield showed that there was no major effect between particle size of 0.25mm to 2.0mm. Gas Chromatography-Mass Spectroscopy GC-MS results showed that the highest percentage area of compound present in the liquid oil was in the order of nonacosane etracosane octadecane heptacosane hexacosane phenol tetracosahexaene and 2-furanmethanol.
