While such studies have provided valuable information on the overall pyrolysis kinetics, there is scope for more fundamental research using surrogate mixtures to examine the transport and thermochemical processes associated with the biomass pyrolysis and subsequent conversion of bio-oil to fuels. Significant research is also needed on catalytic processes for the production of various gaseous and liquid fuels. In summary, the potential of using biomass pyrolysis and subsequent refining of bio-oils to produce second-generation biofuels is increasingly being recognized.

Computed adiabatic flame temperature versus equivalence ratio ( ) for three different syngas mixtures. model (Aggarwal, 2011). Davis et al. (2005), Li et al. (2007) and others have reported such mechanisms for syngas oxidation. 0 mechanism (Smith web-link), which includes the oxidation chemistry of C1-C3 species, has also been employed. The homogeneous reactor model is based on the mass and energy conservation equations for a transient, spatially homogeneous system containing a gaseous reacting mixture.

Note that the presence of water makes bio-oils immiscible with petroleum-derived fuels. The physical properties of bio-oils are discussed in Czernik (2004). 7 . The typical heating value of bio-oils is about 17 MJ/kg, which is about 40–45% of that of hydrocarbon fuels. 3b shows the temperature dependence of the four main products, namely organics, char, gas, and water, from a typical feedstock. In addition, Bridgwater (2012) lists the physical properties of a representative wood-derived bio-oil.
