The effect of phosphorus catalysts for hydrogenation reactions were studied in this work. Different catalysts supported on γ-Al2O3 containing phosphorus (WNiP/γ-Al2O3, MoNiP/γ-Al2O3, WMoNiP/γ-Al2O3 and WMoCoP/γ-Al2O3) were prepared through ultrasonic-assisted impregnation and temperature-programming methods. The catalytic hydrotreating reaction are under the reaction conditions of PH2=9MPa, Thf=370oC, space velocity=0.5h-1, and H2/oil ratio=1400. Gasoline (≤180oC) and diesel (180–360oC) are separated from the liquid product. The fractions were characterized by Elemental analysis, FTIR, KY3000 S/N and GC-MS analysis. Though analysis of test results, it can be concluded that the WNiP/γ-Al2O3 is the excellent hydrotreating catalyst in this series at this reaction condition.

Solvent incompatibility is a limiting factor when implementing 2D-HPLC. A programmed temperature gradient in the first dimension was developed to overcome this limitation by allowing an isocratic separation while maintaining selectivity.
