Abstract
A composition that comprises a support material having incorporated therein a metal component and impregnated with both hydrocarbon oil and a polar additive. The composition that is impregnated with both hydrocarbon oil and polar additive is useful in the hydrotreating of hydrocarbon feedstocks, and it is especially useful in applications involving delayed feed introduction whereby the composition is first treated with hot hydrogen, and, optionally, with a sulfur compound, prior to contacting it with a hydrocarbon feedstock under hydrodesulfurization process conditions.
Claims23
A composition, comprising:
- a support material that is loaded with an active metal precursor, a hydrocarbon oil, and a polar additive having a dipole moment of at least 0.45, wherein the weight ratio of said hydrocarbon oil to polar additive is in the range upwardly to 10:1, and wherein said support material is thereafter treated with a gas comprising hydrogen.
A composition, comprising:
- a support material containing a metal component of a metal salt solution, hydrocarbon oil, and a polar additive having a dipole moment of at least 0.45, wherein the weight ratio of said hydrocarbon oil to polar additive is in the range upwardly to 10:1.
A method of making a composition, wherein said method comprises:
- incorporating a metal-containing solution into a support material to provide a metal-incorporated support material;
- and
- incorporating hydrocarbon oil and a polar additive having a dipole moment of at least 0.45 into said metal-incorporated support material to thereby provide an oil and additive impregnated composition having a weight ratio of said hydrocarbon oil to polar additive is in the range upwardly to 10:1.
