Molecular Transformation of Vacuum Gas Oil in Hydrodesulfurization.

Molecular Modeling of Gas Oil Hydrodesulfurization

The hydrodesulfurization (HDS) process chemistry and reaction network have been modeled at the molecular level. The following sulfur compound types have been considered: mercaptans, sulfides, disulfides, thiophenes (T), benzothiophenes (BT), dibenzothiophenes (DBT), and their alkyl and hydrogenated derivatives. The steric and electronic effects of the alkyl side chain of thiophenic compounds (T...

Effect of acidity and physical properties of nanozeolite catalyst on hydrocracking of vacuum gas oil

In this study, beta nanozeolite, ultra-stable Y zeolite (USY) and amorphous silica-alumina (ASA) were synthesized. These compounds were used as the support of hydrocracking catalyst. Ni-Mo/beta zeolite-ASA and Ni-Mo/USY zeolite-ASA catalysts were prepared by the impregnation method. The samples were characterized with X-Ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM)...

Optimizing the vacuum gas oil hydrocracking process temperature in the presence of Ni-Mo/γ-Al2O3-SiO2 catalyst

A suitable model for predicting the product quality of vacuum gas oil (VGO) catalytic hydrocracking is developed. Data were obtained using an experimental catalytic hydrocracking reactor loaded with the Ni-Mo/Al2O3-SiO2 catalyst. A set of experimental runs was conducted under various operating temperatures from 380 to 450 ℃. Three distribution models were used t...
