Effect of Crude Oil Properties on the Hydrodesulfurization of Middle Distillates over NiMo And CoMo Catalysts

摘要

The effect of crude oil properties on hydrodesulfurized diesel quality was studied in a hydrotreating fixed-bed pilot plant. Three HDT feeds were prepared by blending the straight- run middle distillates obtained by TBP fractionation of crude oils in the following volumetric ratios: 60/100 straight-run gas oil, 20/100 kerosene, and 20/100 jet fuel. Pilot plant experiments were conducted at constant reaction pressure (54 kg/cm~2) and hydrogen-to-oil ratio (2000 ft~3/bbl).
