| Pyrolysis of forestry residues is currently of great interest because bio-oil compounds are produced and these can be employed for the hydrogen production from steam reforming. The objective of the present research was to perform a kinetic study and to determine the optimum reaction conditions for the pyrolysis of the Mexican species Pinus cooperi and Quercus sideroxyla to achieve the greatest amount of volatile matter (condensable and non-condensable). Furthermore, a thermodynamic analysis was made to evaluate its possible application towards the steam reforming of the volatile matter combined with CO2 absorption (AERS). Samples of forest biomass were crushed and sieved to particle sizes between 300 to 710 μm and evaluated in a pyrolytic reactor under a N2 flowrate of 50, 100 and 150 ml/min, at heating rates of 1, 5, 10, 15, 20 and 25 °C/min from room temperature to 700 °C. Results show that at a particle size of 300 microns, 100 ml/min and SV = 33000 h -1 and heating rate of 20 °C/min, allowed to obtain the greatest amount of volatile matter in both species. Proximate analysis (wt%) for Pinus cooperi resulted in 3.01% moisture, 78.01% volatile matter, 12.35% fixed carbon, 0.42% ash and 6564 J/g of calorific value, while for Quercus sideroxyla specie was 2.39% moisture, 78.69% volatile matter, 18.24% fixed carbon, 0.45% ash and a 7322 J/g of calorific value. Kinetic study of the pyrolysis shown an activation energy of Ea = 201.24 kJ/mol for Pinus cooperi and 141.97 kJ/mol for Quercus sideroxyla, respectively with an apparent reaction order of 1 for both species. Finally, through the thermodynamic analysis, it was found that the obtained volatile species showed a high potential for the production of hydrogen under the steam reforming combined with CO2 absorption reaction scheme (AESR). | |
