Growing concerns on shrinking of fossil fuel resources has led to increased fuel costs which in turn lead to climate change issues which pays greater attention for the need of alternate energy fuels. As a result of photosynthesis, biomass is the only formed renewable resource which provides about 14% of global energy needs that is capable to substitute fossil fuels (Kaygusaz, 2002). Among the various energy conversion routes, thermochemical conversion technique can be used to generate fuel in different forms. In recent days, different approaches are coming up based on pyrolysis related bioenergy transformation processes. By selecting proper operation temperatures, pyrolysis can be focused on the production of solid (Slow pyrolysis: 400 to 500 C and hydrothermal carbonization: 180 to 220 C) products, liquid (Fast pyrolysis: 900 C) and gaseous (Gasification: 1100 C)(Digman et al., 2009).
