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...

Carbon dioxide can be utilized as a feedstock to produce chemicals and renewable fuels sustainably. CO2 hydrogenation hydrocarbons through methanol mediated pathway requires more detailed study, examining interactions between reaction processes leading different product selectivities. In this particular work, we propose kinetic model for the direct hydrocarbon products over an In2O3/HZSM-5 bifu...

In the present work, the transformation of m-xylene was studied over fresh and pre-coked HZSM-5 catalyst in a riser simulator over the temperature range of 350-500C.Significant differences were observed in both the activity and product selectivity pattern for the two forms of the catalyst. While, the fresh catalyst generally gave higher m-xylene conversion, the pre-coked catalyst produced highe...

Summary Molybdenum supported on zeolite HZSM-5 is the most studied catalyst for methane dehydroaromatization. However, nature of its catalytic sites and their deactivation mechanisms remain unclear controversial. Here, we report further insights into this system: first, crystal size determines form location active MoCx species, thus performance; second, are preferentially deactivated over acid ...
