Abstract
A hydroprocessing catalyst composition that comprises a metal-incorporated support having incorporated therein a metal component and a chelating agent, and, further comprising a polar additive. The catalyst composition is prepared by incorporating in a single step at least one metal component and a chelating agent into a support material to form a metal-incorporated support followed by drying the metal-incorporated support and thereafter incorporating therein a polar additive.
Claims6
A hydroprocessing catalyst composition, comprising:
- a dried metal-incorporated support, and
- an incorporated polar additive;
- wherein said dried metal-incorporated support comprises a dried and calcined shaped support particle, having incorporated therein a metal component and a chelating agent selected from the group of compounds consisting of aminocarboxylic acids, polyamines, aminoalcohols, oximes, and polyethyleneimines, which has been dried thereby providing said dried metal-incorporated support;
- wherein said incorporated polar additive is selected from the group of amide compounds having a polarity and a dipole moment of at least 0.45, and
- wherein at least 75% of the available pore volume of said dried metal-incorporated support is filled with said polar additive.
