G. Marroquin-sanchez et al., Effect of crude oil properties on the hydrodesulfurization of middle distillates over NiMo and CoMo catalysts, ENERG FUEL, 15(5), 2001, pp. 1213-1219
The effect of crude oil properties on hydrodesulfurized diesel quality was
studied in a hydrotreating fixed-bed pilot plant. Three HDT feeds were prep
ared by blending the straight-run middle distillates obtained by TBP fracti
onation of crude oils in the following volumetric ratios: 60% straight-run
gas oil, 20% kerosene, and 20% jet fuel. Pilot plant experiments were condu
cted at constant reaction pressure (54 kg/cm(2)) and hydrogen-to-oil ratio
(2000 ft(3)/bbl). The effect of reaction temperature and liquid hourly spac
e velocity were studied in the range of 340-360 degreesC and 1.5-2.0 h(-1),
respectively, over two commercial catalysts (NiMo and CoMo). The effect of
crude oil properties on product quality is analyzed in terms of hydrodesul
furization, hydrodenitrogenation, and aromatics removal.
