4-Lump kinetic model for vacuum gas oil hydrocracker involving hydrogen consumption [PDF]

Korean Journal of Chemical Engineering, 2010
A 4-lump kinetic model including hydrogen consumption for hydrocracking of vacuum gas oil in a pilot scale reactor is proposed. The advantage of this work over the previous ones is consideration of hydrogen consumption, imposed by converting vacuum gas ...

Mild hydrotreatment of biocrude derived from hydrothermal liquefaction of agriculture waste: improving biocrude miscibility with vacuum gas oil to aid co‐processing

Biofuels, Bioproducts and Biorefining, 2021
The co‐processing of biocrude in petroleum refineries is viewed as an economical and practical pathway to produce low‐carbon fuels. A major challenge to co‐processing is the poor miscibility of biocrudes with petroleum due to their high levels of oxygen.

Mathematical Modeling of the Vacuum Gas Oil Hydrotreatment

Kataliz v promyshlennosti, 2022
Thermochemical properties of molecules and thermodynamic characteristics of vacuum distillate hydrotreatment were calculated by quantumchemical methods. A kinetic model of the hydrotreatment process was developed using a formalized transformation scheme of hydrocarbons. The developed kinetic model was employed in numerical studies aimed to estimate the

Hydrotreating of a Vacuum Gas Oil-Heavy Coker Gas Oil Mixture

Russian Journal of General Chemistry, 2018
Changes in the chemical composition of the vacuum gas oil in a mixture with heavy coker gas oil in the presence of industrial and laboratory NiMoW/P2O5–Al2O3 catalyst were studied. The support used was γ-Al2O3, prepared from AlOOH powder TH-60 (Sasol), with the following textural characteristics: SBET = 205 m2/g, Vpore = 0.682 cm3/g, Reff = 48 A ...
