In this work, we have investigated the complicated reaction network of biomass catalytic fast pyrolysis, particularly decomposition key cellulose pyrolysis intermediate, levoglucosan. Fast levoglucosan using a Py-GC-MS-FID system in presence HZSM-5 suggested that furan and furfural are intermediates to aromatic hydrocarbons. This was followed by theoretical modelling adopting density functional...

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...

The kinetics of toluene hydrogenation over Ni-supported catalysts with various supports was investigated under the wide range of conditions as 130 to 210 °C reaction temperature, 2.6×10-5 to 5.9×10-5 atm partial pressure of hydrogen and 1.4×10-9 to 3.7×10-8 atm partial pressure of toluene. For more study, two kinetics models were also selected and studied to describe the kinetics of this proces...
