Effect of nitrogen post-doping on a commercial platinum–ruthenium/carbon anode catalyst Report Title This work investigates the effects of after-the-fact chemical modification of a state-of-the-art commercial carbonsupported PtRu catalyst for direct methanol fuel cells (DMFCs). A commercial PtRu/C (JM HiSPEC-10000) catalyst is post-doped with nitrogen by ion-implantation, where “post-doped” den...
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...
Kinetic Study and Modelling of n-Heptane Reforming Process over Pt/Zr-HMS/HZSM-5 Composite Catalysts
Pt/Zr(x)-HMS/HZSM-5 catalysts with various Si/Zr ratios (as x) were used for investigation of the kinetics of n-heptane reforming process under 350 - 450 oC reaction temperature, 35 to 80 ml min-1 flowing rate of hydrogen and 2 to 5 ml h-1 flowing rate of n-heptane. In the present work, two kinetics (power law and Langmuir - Hinshelwood) models were selected and examined to describe the kinetic...
Catalytic fast co-pyrolysis of sewage sludge and sawdust was performed using Py/GC-MS for pyrolytic product upgrades. Metal oxides (NiO MoO3) ZSM-5 catalysts had been introduced into single catalytic pyrolysis. The combination NiO + MoO3 in mixed metal (MMOs) modified with under a dual-catalyst different layouts. In the pyrolysis process, specifically promoted formation phenols, ketones, furans...
