Nanoscale nickel phosphide catalysts for hydrotreatment

摘要

This present disclosure is directed to methods for the preparation of a hydrotreatment catalyst, such as nanoscale nickel phosphide (i.e., Ni₂P) particles supported on high-surface area metal oxides (e.g., silica, alumina, amorphous silica-alumina), in a manner that is compatible with conditions employed in commercial hydrotreating units. The catalyst synthesis includes impregnation, drying, and in situ reduction, and can provide highly active catalysts for the removal of S and N impurities from crude oil fractions.
