Abstract

This paper described conversion of Jatropha curcas waste into solid fuel through densification. The J. curcas waste contains 61-67% cake seed per unit weight. The densification makes a cake seed easy to collect, ship, store and use. The cake seed is useful as a solid fuel. Initially, the waste was examined with proximate and heating value analyses which were used to identify moisture, volatile matter and ash contain. Next, the fixed bed reactor was adopted as the process of the combustion characteristic identification. The results showed that the increasing surface area per mass reduced the reaction time. Meanwhile, the increasing diameter of the cake seed pellet would result in decreasing combustion gas temperature. The diameter of the pellet did not influence CO emission significantly. The highest CO emission was found at the air flow veloocity of 0.1 m s-1 and temperature of 222 °C.
