Vessel for containing catalyst in a tubular reactor
View Patent ↗In a catalyst carrier for insertion in a tube of a reactor, an annular container holds the catalyst in use and has a perforated inner wall defining a tube, a perforated outer wall, a top surface closing the annular container and a bottom surface closing the annular container. A surface closes the bottom of the tube formed by the inner wall of the annular container. A skirt extends upwardly from the perforated outer wall of the annular container from a position at or near the bottom surface to a position below the location of a seal located at or near the top surface and extending from the container by a distance which extends beyond an outer surface of the skirt.
1. A catalyst carrier for insertion in a tube of a tube reactor, said catalyst carrier comprising:
an annular container for holding catalyst in use, said container having a perforated inner wall defining a tube, a perforated outer wall, a top surface closing the annular container and a bottom surface closing the annular container;
a surface closing the bottom of said tube formed by the inner wall of the annular container;
a skirt extending upwardly from the perforated outer wall of the annular container from a position at or near the bottom surface of said container to a position below the location of a seal; and
a seal located at or near the top surface and extending from the container by a distance which extends beyond an outer surface of the skirt.
2. The catalyst carrier according to claim 1 wherein one or more drain holes is located in the bottom surface.
3. The catalyst carrier according to claim 1 wherein one or more drain holes is located in the surface closing the bottom of the tube.
4. The catalyst carrier according to claim 1 wherein one or more spacer means extend downwardly from the bottom surface of the annular container.
5. The catalyst carrier according to claim 1 wherein upper surface closing the annular container include means to locate the container against a catalyst carrier stacked above the container in use.
6. The catalyst carrier according to claim 1 wherein the upwardly extending skirt is shaped.
7. The catalyst carrier according to claim 6 wherein the shaping on the upwardly extending skirt is corrugations.
8. The catalyst carrier according to claim 6 wherein the shaping of the upwardly extending skirt is flattened to a smooth configuration towards the point at which it is connected to the annular container.
9. The catalyst carrier according to claim 1 including catalyst.
10. A reactor tube comprising a plurality of catalyst carriers of claim 1 .
11. A reactor including one or more reactor tubes Of claim 10 .
12. A process for carrying out a reaction wherein the reactants enter into the catalyst carrier of claim 1 .
13. The process according to claim 12 wherein the reactants pass radially through a catalyst bed.
14. The process according to claim 12 wherein the reaction is one of an exothermic reaction and an endothermic reaction.
