【 摘 要 】

Pyrolysis is known as a heating method which can decompose biomass to be the char in the absence of oxygen by providing carrier gas into the furnace. In practice, not all laboratories are equipped with carrier gas. Especially in large scale production, high cost production become the main problem. In this study, we propose simple pyrolysis method without carrier gas to produce coconut shell char as one of the biomass sources. The purpose of this research was to produce the coconut shell char using the simple pyrolysis method to obtain high purity carbon with low oxygen content. Experimental studies focused on the additional treatments complement to the pyrolysis process of the coconut shell. These treatments are proposed to minimize the oxygen content in the char. In this case, the oxygen bind to the carbon can reduce the carbon pore size. The produced coconut shell char were characterized by employing SEM-EDX, XRD, FTIR and Nitrogen Isotherm Physisorption. It was found that the treatments potential to reduce the oxygen content, contaminant and also increase the carbon yield.
