Descripción : | The effect of deasphalting of heavy oil with different degrees of asphaltenes precipitation on catalytic
hydrotreating is reported in this work. Deasphalted oils were obtained in a pressurized vessel using nheptane
and n-pentane as solvents. Various samples with different amounts of asphaltenes were
prepared by varying precipitation conditions. Hydrotreating of deasphalted oils was conducted with a
commercial NiMo catalyst in a batch reactor at the following reaction conditions: hydrogen pressure of
100 kg/cm2, temperature of 400 8C, stirring rate of 750 rpm and reaction time of 4 h. The heavy oil, the
deasphalted oils and the hydrotreated products were characterized by sulfur, metals (Ni, V), asphaltene
contents, and API gravity. Metals and carbon contents as well as textural properties and X-ray diffraction
were also determined on fresh, spent and regenerated catalysts. http://www.sciencedirect.com/science/article/pii/S0920586109006014 |
