Catalytic pyrolysis mechanism of both catalysts had shown significant effect on the degradation of RH. Model free kinetic of iso-conversional method (Flynn-Wall-Ozawa) and multi-step reaction model (Distributed Activation Energy Model) were employed into present study. The average activation energy was found in the range of 175.4�177.7 kJ mol�1 (RH), 123.3�132.5 kJ mol�1 (RH-LS), and 96.1�100.4 kJ mol�1 (RH-ES) respectively. The syngas composition had increased from 60.05 wt to 63.1 wt (RH-LS) and 63.4 wt (RH-ES). However, the CO2 content had decreased from 24.1 wt (RH) to 20.8 wt (RH-LS) and 19.9 wt (RH-ES). © 2018 Elsevier Ltd publisher: Elsevier Ltd date: 2018 type: Article type: PeerReviewed identifier: Gan, D.K.W. and Loy, A.C.M. and Chin, B.L.F. and Yusup, S. and Unrean, P. and Rianawati, E. and Acda, M.N.
