摘要
Pyrolysis of forestry residues produces bio-oil compounds and potentially employed in H-2 production. This research is aimed to perform a kinetic study and obtain optimum reaction conditions (ORC) for the pyrolysis of the Mexican Pinus cooperi (PC) and Quercus sideroxyla (QS) forest species to obtain the maximum amount of volatile matter (condensable and non condensable). Samples of forest biomass were crushed and sieved to 300 >= dp >= 400 mu m and 600 >= dp >= 700 mu m and evaluated in a reactor under a N2 flowrate at 50, 100 and 150 ml/ min, and heating rates (beta) of 1, 5, 10, 15, 20 and 25 degrees C/min from 25 to 700 degrees C. Results show that ORC were: 300 >= dp >= 400 mu m, 150 ml/min and beta = 25 degrees C/min, for both species. Kinetic study of the pyrolysis shown an Ea = 153.6 kJ/mol for PC and 200.51 kJ/mol for QS, respectively and n = 1 for both species. Preliminary thermodynamic analysis of steam reforming and CO2 absorption (Na2ZrO3) of bio-oil resulted in a maximum of 98.57% hydrogen production.
