A high level of hydrodenitrogenation (HDN) is required to achieve a desirable conversion of
other hydroprocessing reactions. This results from a strong adsorption of nitrogen …

In this work, a series of nickel–molybdenum, nickel–molybdenum–boron and one nickel–
molybdenum–phosphorus catalysts were prepared by incipient wetness impregnation …

Studies of catalytic activity of a series of nickel–molybdenum catalysts supported on Al2O3
modified with borate ions were performed for the hydrotreating of coal liquid. Decomposition …

Siliceous MCM-41 with different amount of alumina, from 0.25 up to 4.0 wt%, were prepared
by impregnation of the MCM-41 with aqueous solution of Al (NO) 3· 9H2O. The modified …

化石燃料的加氢脱氮有利于改善油品质量及其稳定性, 同时避免燃烧时NOx 的排放.
本文介绍了不同化石燃料中有机氮化物的含量及类型, 对不同加氢脱氮催化剂及其催化活性位的 …

Catalytic hydrodesulfurization (HDS) technique is widely used for clean gasoline production.
However, traditional HDS catalyst (CoMo/γ-Al 2 O 3) exhibits high hydrogenation …

Selective ring opening (SRO) is an attractive route for increasing the cetane number of
diesel fuels. Noble metal-based catalysts have been proposed for this purpose. However …

This research presents a series of catalytic supports of MCM41 modified with γ-Al 2 O 3 with
a Si/Al molar ratio of 10, 25 and 50. These materials were impregnated with Ni+ W solutions …

The effect of fluorine on the hydrogenation of cyclohexene over sulfided NiMo catalysts
supported on Al2O3 and amorphous silica–alumina (ASA) was studied at 5.0 MPa and …

A detailed experimental study was performed in a trickle-bed reactor using bitumen derived
gas oil. The objective of this work was to compare the activity of NiMo/Al2O3 catalyst …
