Abstract

A catalyst reactor basket is provided that includes an outer side wall extending along the outer circumferential periphery and an inner side wall disposed within the outer side wall. An aperture is sized and shaped to allow a fluid to flow axially with respect to the basket. First and second covers are disposed on opposite ends of the outer side wall and inner side wall and a dividing wall is disposed between the first and second covers. The dividing wall defines a first and second chamber within the inner volume of the basket. A plurality of partitions are disposed within the first and second chambers. The plurality of partitions define a plurality of compartments within the first and second chambers, each compartment being sized and shaped to receive a catalyst.

First claim

What is claimed is:

1. A catalyst reactor basket arranged to receive a combination of catalysts in separate chambers, comprising:
an outer side wall extending along the outer periphery of the basket and extending to define an inner volume of the basket;
an inner side wall disposed within the outer side wall, the inner side wall extending to define an aperture that defines a inner boundary of the volume of the basket, the aperture being sized and shaped to allow a fluid to flow axially with respect to the basket;
first and second covers disposed on opposite ends of the outer side wall and inner side wall, the first and second covers defining respective ends of the inner volume of the basket, at least a portion of the first and second covers being fluid permeable; and
a dividing wall disposed between the first and second covers, the dividing wall defining a first and second chamber within the inner volume of the basket, at least a portion of the dividing wall being fluid permeable, wherein each of the first and second chambers being sized to receive a respective catalyst so as to enable a two-stage reaction in a single pass of the fluid in the axial direction.

2. The catalyst reactor basket as in claim 1 , further comprising a plurality of partitions disposed within the first and second chambers, each partition extending between the outer side wall and the inner side wall and between the dividing wall and a respective cover, the plurality of partitions defining a plurality of compartments within the first and second chambers, each compartment being sized and shaped to receive a catalyst.

3. The catalyst reactor basket as in claim 2 , wherein a first compartment in the first chamber is aligned with a second compartment in the second chamber along an axis of the basket such that any fluid can flow through the first compartment and subsequently flow through the second compartment.

4. The catalyst reactor basket as in claim 3 , wherein first compartment is sized to receive a first catalyst and the second compartment is sized to receive a second catalyst such that the fluid first contacts the first catalyst and subsequently contacts a second catalyst along an axial flow path of the fluid.

5. The catalyst reactor basket as in claim 4 , wherein the first catalyst has properties that are different from the second catalyst.

6. The catalyst reactor basket as in claim 2 , wherein the partitions provide a fluid barrier between adjacent compartments.

7. The catalyst reactor basket as in claim 2 , wherein at least one compartment is sized to receive a first catalyst that has different properties than a second catalyst in an adjacent compartment.

8. The catalyst reactor basket as in claim 1 , further comprising a support frame wherein the outer wall, inner wall, and dividing wall are supported by the frame.

9. The catalyst reactor basket as in claim 1 , further comprising clips that removably secure the covers to respective ends of the basket.

10. The catalyst reactor basket as in claim 1 , further comprising hooks coupled to the basket, the hooks being sized and shaped to support the basket such that the basket hangs from the hooks.

11. The catalyst reactor basket as in claim 1 , wherein at least a portion of the inner side wall is fluid permeable.

12. The catalyst reactor basket as in claim 1 , wherein at least a portion of the outer wall is fluid permeable.

13. A method of catalyzing a fluid, the method comprising:
disposing a catalyst reactor basket in a reactor, the basket defining a volume and having a fluid permeable dividing wall within the volume of the basket;
receiving a first catalyst within a first chamber on a first side of the fluid permeable dividing wall and a second catalyst within a second chamber on a second side of the fluid permeable dividing wall; and
flowing the fluid in the reactor through the first and second chambers of the catalyst reactor basket and across the fluid permeable dividing wall.

14. The method of claim 13 , wherein the first chamber is aligned with the second chamber along an axis of the basket, the method further comprising flowing the fluid through the first chamber and subsequently through the second chamber along the axis of the basket.

15. The method of claim 14 , wherein the flowing step comprises contacting the fluid with the first catalyst in the first chamber and subsequently contacting the fluid with the second catalyst in the second chamber.

16. The method of claim 13 , further comprising:
partitioning at least one of the first and second chambers into a plurality of partitions which define a respective plurality of compartments,
wherein the receiving step comprises loading a catalyst into each partition.

17. The method of claim 16 :
wherein the fluid flows in an axial direction,
wherein the partitions in the first chamber are aligned with the partitions in the second chamber such that the compartments in the first chamber are aligned with the compartments in the second chamber in the axial direction, and
wherein the partitions are not fluid permeable,

the flowing step further comprising flowing the fluid through the compartments in the first chamber and subsequently flowing the fluid through the compartments in the second chamber along the axial direction.

18. The method of claim 17 , wherein each catalyst in the first chamber is different from each catalyst in the second chamber, the flowing step further comprising flowing the fluid through the first chamber and subsequently flowing the fluid through the second chamber, the fluid contacting different combinations of catalysts in respective aligned compartments as it flows axially from the first chamber to the second chamber.

19. The method of claim 13 , wherein the catalyst reactor basket further comprises first and second covers spaced from the fluid impermeable dividing wall, first clips to removably secure the first cover and second clips to removably secure the second cover, the method comprising, prior to the step of disposing the catalyst reactor basket in the reactor:
loading the first catalyst within the first chamber;
placing the first cover on the catalyst reactor basket;
securing the first cover with the first clips;
flipping the basket over;
loading the second catalyst within the second chamber;
placing the second cover on the catalyst reactor basket; and
securing the second cover with the second clips.

20. The method of claim 13 , wherein the catalyst reactor basket has hooks coupled to the basket, the method further comprising using the hooks to couple the basket to the reactor.
