Özet

This paper investigates exergetic performance of gasification and pyrolysis processes and compares their exergy efficiencies, using the experimental data on a two-step process of thermo-chemical conversion of Wood Board (WB) wastes. The exergy values of biomass samples change from 17.49 MJ/kg to 24.57 MJ/kg, respectively. Hydrogen produced from pyrolysis step of gasification varies between 17 (%v/v) and 47 (%v/v) and ranges from 17.1 to 42.6 (%v/v) in pyrolysis. The exergy contents of hydrogen range from 2.20 kJ to 16.26 kJ with the highest efficiency of 93% in pyrolysis step of gasification of WB_1000 samples, and from 2.01 kJ to 10.43 kJ with the highest efficiency of 51% in pyrolysis of WB_250_1000 samples.
