Abstract:
A composition that comprises a support material having incorporated therein a metal component and impregnated with an additive compound that is selected from the group of heterocyclic, polar compounds of the formula CxHnNyOz; wherein: x is an integer of at least 3; y is either 0, 1, 2, or 3; z is either 0, 1, 2, or 3; and n is the number of hydrogen atoms required to fill the remaining bonds with the carbon atoms of the molecule. The composition includes the support material that is impregnated with the additive compound and is useful in the hydroprocessing of hydrocarbon feedstocks, especially in the denitrogenation and desulfurization of distillate feedstocks to make ultra low sulfur diesel.

Abstract:
A composition having a substantial or material absence of or no phosphorous and comprising a support material, a metal compound and either a hydrocarbon oil or a polar additive or a combination of both a hydrocarbon oil and polar additive. The polar additive has particularly defined properties including having a dipole moment of at least 0.45. The composition is useful in the hydroprocessing of hydrocarbon feedstocks, and it is especially useful in the hydrotreating of vacuum gas oils and petroleum resid feedstocks.
