The thermochemical settlement characteristics of Sudan Palouge FPF water cut crude oil joined different types of demulsifier through the indoor experiment was studied. The results show that: for the crude oil emulsion with different water content on different emulsification condition, the best emulsion breaking temperature for the demulsifier TS-101 is 80°C, the optimum concentration is 170~180 mg/L, most of the oil samples tend to be stable after settled for 13 hours, 19 hours later all of the oil samples met the target that the water content is less than 5% after dehydration.

A novel solution-phase low temperature synthesis of a supported Ni 2P catalyst is described. This uses nickel acetylacetonate (Ni(acac)2) and low cost triphenylphosphine (TPP) in the presence of the coordinating solvent tri-n-octylamine (TOA) to form Ni2P/MCM-41 catalysts. The catalysts were characterized by X-ray diffraction (XRD), N 2-adsorption specific surface area measurements (BET), CO uptake, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The effects of the synthesis temperature, and initial P/Ni molar ratio on the formation of the Ni 2P phase were studied. The formation of the crystalline phase follows the order Ni < Ni12P5 < Ni2P with increasing synthesis temperature. The high initial P/Ni molar ratio favored the formation and dispersion of the Ni2P phase, and a mixture of the Ni12P5 and Ni2P phases was observed in the sample with the low initial P/Ni molar ratio of 0.5. The dibenzothiophene (DBT) hydrodesulfurization (HDS) activity increased with reaction temperature in all cases. The catalysts synthesized at 603 K with an initial P/Ni molar ratio of 6 exhibited good DBT HDS activity. The DBT conversion was close to 100% at 613 K, which was much higher than that of the catalyst prepared by the conventional temperature programmed reduction (TPR) method (DBT conversion 43%). During the HDS reaction, the superficial phosphosulfide phase NixP ySz was formed on the surface of the catalyst; this showed higher activity than Ni2P. © 2014 Elsevier Ltd. Source

A solution method for preparing a Ni2P catalyst supported on anatase-TiO2 whiskers (Ni2P-PPh3) based on low cost triphenylphosphine (PPh3) is described. This approach suppressed the formation of the TiPO4 phase. The synthesis temperature is modest (603 K). The Ni2P-PPh3 catalyst did not modify the anatase-TiO2 phase in any way, and it showed much higher hydrodesulfurization activity than the same catalyst prepared by the conventional TPR method. © 2013 Elsevier B.V.
