ZrO2 and catalysts were prepared by a co-precipitate method coupled with HZSM-5 zeolite catalyst through mechanical mixing method; these applied to the direct synthesis of aromatic hydrocarbons from syngas an oxygen-containing intermediate route. The physical chemical properties characterized XRD, H2-TPR, CO2-TPD, SEM methods. comparative catalytic effects MgZrOx discussed under different react...

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desor...

Naphthenic acids are naturally occurring carboxylic in crude oil with cyclic or aromatic rings their structure. These responsible for the acidity of oil, leading to corrosion problems refinery equipment and deactivation catalysts while creating a continuous need maintenance. Therefore, removing naphthenic has become an important requirement refining acidic oil. In this paper, experiments conduc...
