Study on production of low sulfur and/or low aromatics diesel fuels from Mideast high sulfur content straight run gas oil was conducted on a hydrotreating pilot plant. The effects of the processing parameters on the degrees of desulfurization and aromatics reduction were investigated. Test results showed that low sulfur diesel fuels (S<0. 05 wt% ) can be produced with RN-1 high-activity catalyst under mild-seventy conditions (PH=3. 2 MPa, LHSV=3. 0h-1), and low sulfur and low aromatics diesel fuels (S<0. 05...

The effects of the endpoint of feedstocks and hydrogen sulfide content in recycle gas on HDS conversions were also studied.

The effects of process parameters, such as temperature, pressure, space velocity and the ratio of hydrogen to feed oil, on deep hydrodesulfurization (HDS) of LCO from FCC over RN 1 catalyst were studied. Based on pilot plant data, the kinetic models for deep HDS of LCO were established. An artificial neural network was created to identify the complicated relationship between properties of feeds and their HDS performances.

W based deep hydrodesulfurization (HDS) catalysts were prepared by impregnating Ni W and Co W species on siliceous MCM 41. The HDS activity of prepared catalysts was evaluated in a fixed bed reactor by using a model fuel containing 0.5% dibenzothiophen (DBT) in decalin and a straight run diesel containing 2.83% S as the feedstocks. Results indicated that the optimal atomic ratio of n (Ni or Co)/ n (W) for both Ni W/MCM 41 and Co W/MCM 41 are 0.75, while Ni W/MCM 41 exhibited much higher HDS...

W based deep hydrodesulfurization (HDS) catalysts were prepared by impregnating Ni W and Co W species on siliceous MCM 41. The HDS activity of prepared catalysts was evaluated in a fixed bed reactor by using a model fuel containing 0.5% dibenzothiophen (DBT) in decalin and a straight run diesel containing 2.83% S as the feedstocks. Results indicated that the optimal atomic ratio of n (Ni or Co)/ n (W) for both Ni W/MCM 41 and Co W/MCM 41 are 0.75, while Ni W/MCM 41 exhibited much higher HDS activity than Co W/MCM 41. The product distribution suggested that the two catalysts took different reaction routes for hydrodesulfurization. For Co W/MCM 41catalyst, hydrodesulfurization took place mainly through hydrogenolysis, i.e. DBT to form BP(biphenyl). As for Ni W/MCM 41 catalyst, both hydrogenolysis and hydrogenation took place, i.e. DBT firstly hydrogenated to form tetrahydro DBT(TH DBT), then desulfurized to form cyclohexyl benzene(CHB). Ni W/MCM 41 catalysts showed excellent performance in the hydrodesulfurization of both DBT and a high sulfur containing stright run diesel, suggesting that siliceous MCM 41 is a promising support for deep HDS catalysts.

用全硅MCM 41担载Ni W和Co W制备了深度加氢脱硫催化剂 ,并在中压固定床反应器上分别考察了对二苯并噻吩 (DBT)和高硫直馏柴油的加氢脱硫性能。结果表明 ,全硅MCM 41担载制成的W系催化剂表现出很高的加氢脱硫活性 ,其中Ni W /MCM 41活性高于Co W /MCM 41,但两类催化剂的最佳Ni(Co) /W原子比均为 0 75。从加氢脱硫产物分布看 ,两类催化剂的脱硫反应路径不同 ,在Co W /MCM 41上主要通过氢解脱硫 ,而在Ni W /MCM 41上则是通过氢解以及先经芳环加氢后脱硫的两条路径来进行。对Ni W /MCM 41来说 ,加氢活性随温度升高而升高。
