Characterization of Solid Synthetic Fuel Derived from Physic Nut and Glycerol Waste Using Single Particle Reactivity Analysis


Article Preview

Deteriorated environment resulting from fossil fuel usage as well as foreseeable conventional energy depletion lead to the exploration of alternative fuel materials especially the renewable ones. In this work, characterization of synthetic fuel material formed by pelletization of Jatropha (physic nut) waste using glycerol waste as a binder was carried out in order to investigate the feasibility of utilizing these waste materials as another renewable energy source. Synthetic fuel materials of Jatropha residue mixed with 0-40% glycerol waste were formed to length of about 13 mm and diameter of about 11 mm under pressure of 7 MPa in a hydraulic press. Their thermal conversion properties were studied by using single particle reactivity testing scheme at temperature of 500-900°C under partial oxidation atmosphere. The burning started with a relative short drying phase, followed with a longer pyrolysis time and thereafter the dominated char combustion time which took around 81-89% of total conversion time. The average total conversion time varied from 741 sec to 1873 sec depended mainly on reaction temperature. Higher glycerol content resulted in char with lower density and less shrinkage. Changes in diameter were not strongly depended on glycerol contents. The results suggested that Jatropha residue mixed with glycerol may be utilized as quality solid fuel.
