abstract: Thermogravimetric data, the Coats-Redfern free integral method, and correlation coefficients obtained by use of different reaction models were used to study the kinetic characteristics of non-catalytic and catalytic pyrolysis of biomass. Zeolite catalysts (ZSM-5, MCM-22, and ITQ-2) were mixed with the biomass in the ratio 1:10. Analysis of thermogravimetric data revealed that thermal decomposition occurred at 240-450 °C for both non-catalytic and catalytic pyrolysis of biomass. Two temperature regions, region I 240-330 °C and region II 360-450 °C, were identified and a best-fit model describing the behavior of non-catalytic and catalytic biomass pyrolysis was obtained. Addition of catalyst reduces the activation energy in first region then increases it in the second region for all reaction orders. Chemical reaction and diffusion-controlled reaction mechanisms could be kinetically characterized and enabled good description of the nature of biomass pyrolysis. © Springer Science+Business Media Dordrecht 2015.
