Effect of textural properties of Ni (Nano)supported catalysts on the selective benzene hydrogenation in the vapor phase

Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physicochemical properties of Ni catalysts were characterized by the Xray diffraction, Fouriertransform infrared spectroscopy, scanning electron microscope and N lt;sub gt;2 lt;/sub gt; adsorptiondesorption analysis. The catalytic evaluation revealed that the best selectivity to benzene ( gt; 84%) and high stability with the low coke deposition ( lt; 1.1%) are related to Ni/Folded Sheets Mesoporous MaterialsNo. 16. The kinetics of benzene hydrogenation has been examined as a function of benzene and hydrogen pressures at various temperatures. Two kinetic models based on power law and LangmuirHinshelwood mechanisms were developed for the reaction and compared with the obtained experimental data. The apparent kinetic parameters were estimated using the multiple regression analysis. Both these models present the good results.
