Abstract: In this work a simple pyrolysis route to synthesis nano-carbon powder from Sesame oil is followed. The precursor sesame oil used as the source of hydrocarbon by decomposition at high temperature, is a group I vegetable oil with long chain fatty acid containing 16 or 18 carbon atoms. Experiment was performed in an open air laboratory atmosphere and sophisticated laboratory conditions such as inert gas atmosphere, isolated chamber etc are avoided. The synthesized agglomerates are subjected to Atomic Absorption Spectroscopy to investigate its chemical contents.
