Preliminary Observation on Temperature Effect of Briquetting Cow Manure as a Solid Biofuel

Abstract

The depletion of fossil fuel turns the application of biofuel as an alternative fuel. Conversion of cow manure into briquette is the alternative to reutilize valuable chemical in cow manure. The aim of this study is to observe the suitable temperature for briquetting of cow manure as a solid biofuel. The process involved drying, pulverizing, carbonization and briquetting of cow manure. The carbonization of cow manure took place at three different temperatures; 300 °C (C300), 500 °C (C500) and 700 °C (C700). Some analysis on briquette are performed namely proximate analysis, compressive and caloric value tests. The calorific value for carbonization briquette of 300, 500 and 700 °C were 2434, 2402 and 2372 cal/g respectively. The carbonization of cow manure at 300 °C produced the highest calorific value of briquette. Therefore, preliminary observations indicated that carbonization at 300 °C able to densify the cow manure into briquette as a solid biofuel.
