Abstract

A catalytic distillation structure that may include a rigid framework having at least two grids with a plurality of horizontal fluid permeable tubes mounted to said grids to form a plurality of fluid pathways among the plurality of horizontal fluid permeable tubes. Additionally, each horizontal fluid permeable tubes may have a profile of a six-sided polygon. Further, the catalytic distillation structure may include a plurality of vertically plates or wires connecting vertically aligned tubes of the plurality of horizontal fluid permeable tubes. Furthermore, the plurality of vertically plates or wires connects from a corner of one vertically aligned tubes to a corner of an adjacent vertically aligned tube.

First claim

What is claimed:

1. A catalytic distillation structure, comprising:
a rigid framework having at least two grids spaced apart;
a plurality of fluid permeable tubes mounted to said grids to form a plurality of fluid pathways among the plurality of fluid permeable tubes, wherein each fluid permeable tubes have a profile of a six-sided polygon, wherein each of the fluid permeable tubes extend from a first to a second of the at least two grids;
a plurality of plates or wires connecting and aligning tubes of the plurality of fluid permeable tubes, wherein the plurality of plates or wires connects from a lowermost corner of one aligned tubes to an uppermost corner of an adjacent aligned tube.

2. The catalytic distillation structure of claim 1 , further comprising a first series of vertically aligned tubes and a second series of vertically aligned tubes, wherein the first series comprises the plurality of fluid permeable tubes arrayed in a parallel, adjacent and aligned columns within the first series, and the second series comprises the plurality of fluid permeable tubes arrayed in a parallel, adjacent and aligned columns within the second series.

3. The catalytic distillation structure of claim 2 , wherein the first series of aligned tubes are offset from the second series of aligned tubes and the fluid permeable tubes of the first series overlap the fluid permeable tubes of the second series without contacting the fluid permeable tubes of the second series of plates to thereby form a tortuous fluid pathway.

4. The catalytic distillation structure of claim 3 , wherein a height of the plurality of plates or wires evenly space apart the fluid permeable tubes in the first series and the second series.

5. The catalytic distillation structure of claim 4 , wherein the first series and the second series are stacked side-by-side a distance apart.

6. The catalytic distillation structure of claim 3 , further comprising a geometry of the six-sided polygon forming a first angle in four corners of the six-sided polygon, a second angle in two corners of the six-sided polygon, wherein the first angle is greater than the second angle.

7. The catalytic distillation structure of claim 6 , wherein the second angle is in the corners of vertically aligned tubes that are connected by the plurality of plates or wires.

8. The catalytic distillation structure of claim 7 , wherein the six-sided polygon comprises two sides of a first length and four sides of a second length.

9. The catalytic distillation structure of claim 8 , wherein the first angle is at a corner of a connection of a side of the first length and a side of the second length and the second angle is at a corner of a connection of two sides of the second length.

10. The catalytic distillation structure of claim 9 , wherein the second length is greater than the first length.

11. The catalytic distillation structure of claim 9 , wherein the second length is shorter than the first length.

12. The catalytic distillation structure of claim 1 , wherein the plurality of fluid permeable tubes and plurality of plates or wires are made of a same material.

13. The catalytic distillation structure of claim 1 , further comprising at least one support rod to rigidly hold the at least two grids a distance apart from each other.

14. The catalytic distillation structure of claim 1 , wherein each of the plurality of fluid permeable tubes have an opening at a first end and second end of said tubes.

15. The catalytic distillation structure of claim 1 , wherein the grids comprises a plurality of openings, wherein the plurality of openings of the grids have a profile equal to the profile of the plurality of fluid permeable tubes.

16. The catalytic distillation structure of claim 1 , wherein a series of aligned tubes connected via the plates or wires do not comprise welds.

17. The catalytic distillation structure of claim 16 , wherein the plurality of fluid permeable tubes are positioned in the plurality of openings of the grids.

18. The catalytic distillation structure of claim 1 , wherein the tubes are horizontal and are aligned vertically.

19. A distillation column reactor for concurrently carrying out reactions and separating the products from the reactants, comprising:
a vertically disposed vessel; and
one or more catalytic distillation structures as recited in claim 1 disposed in the vertically disposed vessel.

20. The distillation column reactor of claim 19 , wherein the rigid framework is removably attached to the vertically disposed vessel by welding, crimping, adhesives, or mechanical fasteners.
