Summary
This chapter briefly introduces the pyrolysis process in terms of kinetics, energetics and economics. In this scope, firstly simple kinetic models are described for biomass pyrolysis and then the product distribution is discussed. The yields of gas, oil and char are predicted by using chemical kinetics, however it is very difficult to predict the yields of each gas species. Therefore, in this chapter, empirical correlations are used together with the elemental balances to predict the yields of gas species for reactor simulation. Also, a detailed application of the empirical relationships from Neves et al. (2011), elemental balances, and energy balance on the prediction of pyrolysis products are given for the simulation of the devolatilization stage in a biomass gasification process. The production of biochar through the pyrolysis process is simply described. Finally the results from several studies on energy balances and the economic feasibility of the addition of biochar application to the normal bio-energy system are summarized.
