The purpose of this study is to identify the deactivation mechanism(s) that occurs during aromatization dilute ethylene at 500 °C on Zn/H-MFI catalyst. More than 15 catalysts, with a Zn/H+ molar ratio ranging from 0 (H-ZSM5) 1.8 (Zn/H-ZSM5), were prepared by wet impregnation. Deactivation does not result Zn sublimation, but coking. function and coke deposition can be modelled simple exponential...

Abstract The present study is dedicated to investigate the kinetic analysis for catalytic co-pyrolysis of palm kernel shell (PKS) and polyethylene waste (HDPE) mixtures with bifunctional HZSM-5 mussel (MS) catalyst. Artificial neural network (ANN) modeling through 17 models based on functions reaction mechanism denoted as chemical reactions, diffusion nucleation growth interfacial phase reactio...
