Study of pyrolysis of ulin wood residues

Abstract

As abundant resources, ulin wood residues could be converted into bioenergy through pyrolysis process. To detail analysis, the pyrolyzer reactor was connected to micro GC for online gas analysis. By comparing to other biomass e.g. pinewood and low-grade coal, the ulin wood residues exhibited similar result when the pyrolysis process started around 400 °C. The char product decreased as elevated temperature due to gasification process. Based on the gas analysis, this pyrolysis produced a gas product which predominant composed of CO. The SEM analysis also showed that the pyrolysis treatment resulted in fine char with nanopores particles. Hence, the reactivity of the solid product would be increased significantly. Therefore, the ulin wood residues could be other alternatives as a renewable energy source through pyrolysis process.
