- W2496300299 abstract "The Bi-Provincial Upgrader (BPU) complex is a grassroots facility jointly owned by Husky Oil, the Government of Canada, and the Provincial Governments of Alberta and Saskatchewan. This chapter reports on the endeavors concerning the selection of catalysts for the gas–oil hydrotreater. The most important parameters for the gas–oil hydrotreating catalysts are the maximization of hydrodenitrogenation (HDN), reduction of polynuclear aromatics (PNA), and hydrodesulfurization (HDS). The relationship between product quality and hydrogen consumption is an economic consideration required only for final catalyst selection. Mo coverage appears to correlate with HDN, PNA reduction, and HDS. There appears to be a direct relationship between the phosphorus content of the catalysts and some component of the hydrogen uptake. Those catalysts that are highly active in HDN also have high hydrogen consumption and consequently have been found to be high in phosphorus content. These results appear to be consistent with those found in the literature where the most beneficial effects of phosphorus have been documented for Ni-Mo/Al 2 O 3 catalysts. These positive effects include better dispersion of the active components, an increase in the octahedral Ni 2+ concentration in the active phase, and possibly a reduction in the acidity of the catalyst. The increase in the Ni 2+ concentration in the active phase is believed to result in increased hydrogenation activity, while the reduction in acidity has been postulated to decrease coke formation." @default.
