Wire standoffs for stackable structural reactors
A wire standoff suitable for use in a tubular reactor, such as a reformer, is described. The wire standoff includes a portion or segment positioned between an outer reactor tube and one or more reactor components located within the tube. The reactor components and the outer tube are prevented from coming into directed contact with one another by the positioning of the wire standoff. The wire standoff can be secured to a reactor component at one of its ends or to a washer located between stacked reactor components. Prevention of the reactor components from contact with the outer tube promotes fluid flow through the reactor and can enhance heat transfer and reactor efficiency for carrying out catalytic reactions.
1. A reactor comprising:
a) an outer tube;
b) one or more reactor components, the one or more reactor components having an outer circumferential face, the one or more reactor components being positioned in the outer tube;
c) a wire standoff, a portion of the wire standoff being positioned between the outer tube and the one or more reactor components to prevent the one or more reactor components from contacting the outer tube; and
d) a washer being positioned in the outer tube,
wherein (i) the wire standoff has an end portion; (iii) the wire standoff is secured to the washer by the end portion; and (iii) the end portion has a hook for securing the end portion to the washer.
2. The reactor of claim 1 , the wire standoff having a diameter in the range of 0.25 to 10 mm.
3. The reactor of claim 1 , the outer circumferential face of the one or more reactor components being spaced at least 0.25 to 10 mm from the outer tube.
4. The reactor of claim 1 , the wire standoff being secured to at least one of the one or more reactor components.
5. The reactor of claim 4 , wherein the end portion of the wire standoff has a straight segment, and the end portion extends inward into the at least one reactor component through its outer circumferential face.
6. The reactor of claim 1 , the portion of the wire standoff positioned between the outer tube and the outer circumferential face of the one or more reactor components being in direct contact with the outer tube and the one or more reactor components.
7. The reactor of claim 1 , the hook of the end portion of the wire standoff having a bend angle in the range of 70 to 180 degrees.
8. The reactor of claim 1 , the washer having an opening for securing the wire standoff.
9. The reactor of claim 8 , wherein the end portion extends through the opening in the washer for securing the wire standoff to the washer.
10. The reactor of claim 1 , wherein the hook forms an open slot, the washer being positioned in the open slot of the hook for securing the wire standoff to the washer.
11. The reactor of claim 1 , further comprising a second washer positioned in the outer tube, the wire standoff having a second end portion, the second end portion of the wire standoff being secured to the second washer.
12. The reactor of claim 11 , the second end portion of the wire standoff having a hook for securing the second end portion to the second washer, wherein the hook of the first end portion and the hook of the second end portion has a bend angle in the range of 70 to 180 degrees.
