Abstract

Abstract: DN-3636 catalyst of the Criterion Company was adopted in a 3.0 Mt/a diesel oil hydrotreating unit in SINOPEC Zhenhai Refining and Chemical Company to produce the diesel meeting the requirements of the national standard (phase Ⅴ). The results show that at the working conditions of feed blended with FCC LCO (12.8% ) and coking diesel (17.4%)，the sulfur content in the hydrotreated diesel is 6.3 μg/g at reactor inlet temperature 340 ℃，the outlet temperature 380 ℃，the average temperature 367 ℃，H2/oil volume ratio of 300, reaction pressure 6.09 MPa, LHSV 1.74h-1. Diesel density decreases by 20.6 kg/m3, the cetane number increases by 3.8 units, and polycyclic aromatic hydrocarbons decreases by 9.3%.

Key words: catalyst, DN-3636, national standard Ⅴdiesel
