Abstract
Official abstract text for this publication.
An illustrative example reformer includes a housing having an inlet plenum, a reforming section, and an outlet. The inlet plenum includes a catalyst situated where a source fluid passing through the inlet plenum will be exposed to the catalyst prior to entering the reforming section.
First claim
Opening claim text (preview).
We claim: 1. A reformer, comprising: a housing including an inlet and an outlet; a reforming section in the housing; an inlet plenum in the housing between the inlet and the reforming section, the inlet plenum including a mesh container; and a catalyst situated in the mesh container in the inlet plenum where a source fluid passing through the inlet plenum will be exposed to the catalyst prior to entering the reforming section. 2. The reformer of claim 1 , wherein the mesh container comprises a tube of mesh material. 3. The reformer of claim 2 , wherein the tube comprises a cylinder having coaxial inner and outer mesh walls and the catalyst is situated between the inner and outer mesh walls. 4. The reformer of claim 1 , wherein the catalyst comprises a pre-reformer catalyst. 5. The reformer of claim 1 , wherein the catalyst comprises nickel. 6. A method of reforming a source fluid, the method comprising: directing the source fluid through an inlet plenum of a reformer; exposing at least some of the source fluid to a catalyst in the inlet plenum; and reforming the exposed source fluid after it exits the inlet plenum, wherein, the catalyst in the inlet plenum is situated in a mesh container and exposing the source fluid to the catalyst comprises directing the source fluid into contact with the mesh container. 7. The method of claim 6 , wherein, the catalyst comprises a pre-reformer catalyst. 8. The method of claim 6 , wherein, the catalyst comprises nickel. 9. The method of claim 6 , wherein, exposing the source fluid to the catalyst comprises directing the source fluid at least partially through the mesh container. 10. The method of claim 6 , wherein the source fluid comprises a hydrocarbon. 11. The method of claim 10 , wherein the source fluid comprises at least one of natural gas, pure methane, ethane, propane or liquefied petroleum gas. 12. The method of claim 6 , wherein the source fluid comprises natural gas.
