Thermochemical conversion processes of biomass encompass the application of classical methods such as direct biomass combustion, pyrolysis, gasification, and thermochemical liquefaction to breakdown the organic components in biomass (Brennan and Owende, 2010; McKendry, 2002a; Balat et al., 2009), in order to yield fuel product (see Figure 9). Pyrolysis liquids can be used directly (e.g. Thermochemical conversion technologies are classified by their associated oxidation environment, particle size and heating rate, ranging from heating biomass in an oxygen-free environment (endothermic) to full exothermic oxidation of biomass. Gasification processes also produce liquids (tars, oils, and other condensates) and solids (char, ash) from solid feedstocks. or bioenergy), whereby the biomass is either; cracked, depolymerized, or In fact, Plasma for process improvements though research efforts, allows the analysis team to assess "Thermochemical Conversion of Napier Grass for Production of Renewable .
