Property analysis of the oils produced from fixed bed pyrolysis process of biomass solid wastes

Many biomass solid wastes are being considered to be potential sources of renewable energy. In this paper, mahogany seeds, sawdust, rice husk and coconut shell are considerable feedstock which are used for pyrolysis system to produce non-conventional fuel. The products obtained while using these feedstock are pyrolysis oil, solid char and gas. The property of the oils produced from different biomass feedstock varies with various parameters; for instance: operating temperature, running time and feed size. This liquid oil can be a non-conventional source of renewable energy if the process is further developed. This paper organizes and summarizes some selected laboratory experiments and literatures on fixed bed pyrolysis of the mentioned biomass feedstock and focuses on the analysis and comparison of the property of the produced liquid oils from them.
