Abstract

A reactor for carrying out catalytic reactions. The reactor includes a reactor component optionally arranged on a central rod in a reactor tube. The reactor component can have fluid ducts for directing fluid flow through the reactor. The fluid ducts are effective for increasing heat transfer in the reactor. The reactor component can further have a washer attached to a top or bottom surface for directing fluid flow.

First claim

What is claimed is:

1. A reactor comprising:
a fan arranged on a central rod in a reactor tube, the fan having an outer diameter face facing the reactor tube for directing fluid flow to contact the reactor tube and promote heat transfer along the reactor tube,
the outer diameter face of the fan having a notch extending around the perimeter of the outer diameter face, the notch being a recessed portion of the outer diameter face of the fan.

2. The reactor of claim 1 , wherein the notch extends uniformly around the perimeter of the outer diameter face of the fan.

3. The reactor of claim 1 , wherein the notch creates a radial gap between the outer diameter face and the reactor tube.

4. The reactor of claim 1 , wherein the notch has a radial depth that extends inward from the outer diameter face of the fan, the radial depth being in the range of 1 to 15 mm.

5. The reactor of claim 1 , wherein the fan has a circular outer diameter face.

6. The reactor of claim 1 , wherein the outer diameter face of the fan has two or more notches.

7. The reactor of claim 1 , wherein the notch has a height and the height is defined by a nose portion of the fan.

8. The reactor of claim 7 , wherein the height is in the range of 4 to 50 mm.

9. The reactor of claim 7 , wherein the nose portion is in contact with the reactor tube.

10. The reactor of claim 1 , wherein the fan has an upper nose portion and a lower nose portion, the upper nose portion and the lower nose portion extend radially around the outer diameter face of the fan.

11. The reactor of claim 10 , wherein the upper nose portion and the lower nose portion define the opening of the notch extending around the perimeter of the outer diameter face of the fan.

12. The reactor of claim 10 , wherein the fan has a middle nose portion and the outer diameter face of the fan has at least two notches.

13. The reactor of claim 1 , wherein the fan has radial fluid ducts for directing fluid flow through the reactor, the fluid ducts being effective to radially guide the fluid flow to contact the reactor tube.

14. The reactor of claim 13 , wherein the fan has a top surface, a bottom surface and the outer diameter face such that the radial fluid ducts terminate along the outer diameter face of the fan to form fluid duct openings facing the reactor tube.

15. The reactor of claim 13 , wherein the fan is a corrugated disk having a center aperture for receiving the central rod.
