Effect of support nature on performance and kinetics of nickel nanoparticles in toluene hydrogenation
Journal Title: International Journal of new Chemistry - Year 2019, Vol 6, Issue 1
Abstract
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 process. The modelling study indicates that the competitive adsorption mechanism provides a good fit towards the experimental data and allows to determine the kinetics parameters. According to these studies, Ni/HZSM-5(40 wt. %)-HMS catalyst has better performance than other prepared catalysts for the toluene hydrogenation process.

First Princiles Study of the Electron Transport Properties of Buthane-dithiol Nano-Molecular Wire
We report a first-principles study of electrical transport in a single molecular conductor consisting of a buthane-dithiol sandwiched between two Au (100) electrodes. We show that the current was increased by increasing...
A theoretical study of dipole moments, energy levels and structural parameters in the Oxymetazoline drug as a nano carrier based on fullerene with changing substitution
Oxymetazoline is a decongestant. It works by constricting (shrinking) blood vessels (veins and arteries) in your body. The nasal formulation acts directly on the blood vessels in your nasal tissues. Constriction of the b...
