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 noncatalytic and catalytic pyrolysis of biomass Zeolite catalysts ZSM5 MCM22 and ITQ2 were mixed with the biomass in the ratio 110 Analysis of thermogravimetric data revealed that thermal decomposition occurred at 240–450 °C for both noncatalytic and catalytic pyrolysis of biomass Two temperature regions region I 240–330 °C and region II 360–450 °C were identified and a bestfit model describing the behavior of noncatalytic 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 diffusioncontrolled reaction mechanisms could be kinetically characterized and enabled good description of the nature of biomass pyrolysisThe authors wish to thank the Mitsubishi Corporation Education Trust Fund and MOHE of Malaysia LRGS insitu catalytic cracking of biomass to polyols alcohol phenolics aromatic and alkanes for financial support Mr Salman Raza Naqvi would also like to acknowledge the National University of Science and Technology NUST Pakistan
