Abstract

A method for analyzing a catalyst in a catalytic reactor that operates under non-isothermal conditions includes the steps of: positioning a catalyst basket within a catalyst bed within the catalytic reactor, the catalyst basket containing catalyst material the forms the catalyst bed; operating the catalytic reactor, the catalyst basket having dimensions such that a temperature difference (ΔT) along an axial direction (height) of the catalyst basket is non-isothermal; and analyzing the catalyst material contained within the catalyst basket. The temperature difference (ΔT) is, in one embodiment, within a range of 1° C. to 40° C. and preferably, within a range of 5° C. to 25° C.

First claim

What is claimed is:

1. A method for analyzing a catalyst in a catalytic reactor that operates under non-isothermal conditions comprising the steps of:
positioning a catalyst basket within a catalyst bed within the catalytic reactor, the catalyst basket containing catalyst material the forms the catalyst bed,
operating the catalytic reactor, the catalyst basket having dimensions such that a temperature difference (ΔT) along an axial direction of the catalyst basket is non-isothermal; and
analyzing the catalyst material contained within the catalyst basket.

2. The method of claim 1 , wherein the temperature difference (ΔT) is within a range of 1° C. to 40′C.

3. The method of claim 1 , wherein the temperature difference (ΔT) is within a range of 5° C. to 25° C.

4. The method of claim 1 , wherein the catalyst bed has a height (h1) and an internal diameter (ID1) and the catalyst basket has a height (h2) and an internal diameter (ID2), wherein h2/ID2 is between 1 and 300, and wherein h2/h1 is between 0.05 and 1.

5. The method of claim 1 , wherein the catalyst basket has an internal diameter of between about 1 cm to 25 cm, a height between 25 cm to 300 cm, and a wall thickness between 0.1 cm and 1 cm.

6. The method of claim 1 , wherein the step of analyzing the catalyst material contained within the catalyst basket comprises the steps of recovering the catalyst material within the catalyst basket and testing the catalyst material to determine one of: catalyst selectivity, activity, and remaining catalyst life.

7. The method of claim 1 , wherein the step of analyzing the catalyst material contained within the catalyst basket comprises the step of analyzing the catalyst material for physical properties and chemical composition.

8. The method of claim 1 , wherein the step of analyzing the catalyst material contained within the catalyst basket comprises the step of determining a metal deposition profile of the catalyst material.

9. The method of claim 1 , wherein the catalytic reactor comprises one of a hydrodesulfurization reactor, a hydronitrogenation reactor, hydrocracking reactor, a hydrogenation reactor and a hydrometallization reactor.

10. The method of claim 1 , wherein the catalyst basket is formed of stainless steel mesh wire and has a tubular cylindrical shape.

11. The method of claim 4 , wherein h2/h1 is between 0.1 and 1.

12. The method of claim 4 , wherein h2/h1 is between 0.2 and 1.

13. The method of claim 4 , wherein h2/h1 is between 0.3 and 1.

14. The method of claim 4 , wherein h2/h1 is between 0.4 and 1.

15. The method of claim 4 , wherein h2/h1 is between 0.5 and 1.
