A nozzle reactor includes a passage having one or more regions with a converging-diverging shape. The nozzle reactor accelerates a reacting fluid to supersonic velocities and mixes it with a feed material. The reacting fluid and the feed material may be pre-heated. The high speed collision between the reacting fluid and the feed material at elevated temperatures causes the materials to react.

1. A nozzle reactor comprising: a main passage including a first region followed by a second region, the first region and the second region each including a convergent section, a throat, and a divergent section; anda feed passage in fluid communication with the main passage;wherein the feed passage meets the main passage between the throat in the first region and the throat in the second region and wherein the main passage expands between the location where the feed passage meets the main passage and the throat in the second region thereby defining an expansion area; anda distributor positioned in the feed passage, the distributor being configured to annularly distribute flow from the feed passage to the main passage. 2. The nozzle reactor of claim 1 wherein the cross-sectional area of the throat in the second region is at least twice as large as the cross sectional area of the throat in the first region. 3. The nozzle reactor of claim 1 comprising a head portion coupled to a body portion, the head portion including the first region and the body portion including the second region. 4. The nozzle reactor of claim 1 wherein the distributor is a physically separate component capable of being removed from the nozzle reactor and replaced. 5. The nozzle reactor of claim 1 wherein the distributor includes a plurality of openings that are part of the feed passage. 6. The nozzle reactor of claim 1 comprising a wear ring through which the main passage passes, the wear ring being positioned immediately adjacent to and downstream of the location where the feed passage meets the main passage, wherein the wear ring is a physically separate component, whereby the wear ring is capable of being removed from the nozzle reactor and replaced. 7. The nozzle reactor of claim 6 comprising a head portion coupled to a body portion, wherein the head portion is separable from the body portion to provide access to the wear ring. 8. A nozzle reactor comprising: a main passage including a convergent section, a throat, and a divergent section;a feed passage in fluid communication with the main passage at a location downstream of the throat;a distributor positioned in the feed passage, the distributor being configured to annularly distribute flow from the feed passage to the main passage; anda wear ring through which the main passage passes, the wear ring being positioned immediately adjacent to and downstream of the location where the feed passage meets the main passage;wherein the wear ring is a physically separate component, whereby the wear ring is capable of being removed from the nozzle reactor and replaced;wherein the main passage expands downstream of the location where the feed passage is in fluid communication with the main passage thereby forming an expansion chamber. 9. The nozzle reactor of claim 8 comprising a head portion coupled to a body portion, the head portion being upstream of the location where the feed passage meets the main passage. 10. The nozzle reactor of claim 9 wherein the head portion is separable from the body portion to provide access to the wear ring. 11. The nozzle reactor of claim 8 wherein the distributor includes the wear ring. 12. The nozzle reactor of claim 8 wherein the distributor is a physically separate component capable of being removed from the nozzle reactor and replaced. 13. A nozzle reactor comprising: a main passage including a convergent section, a throat, and a divergent section;a feed passage in fluid communication with the main passage downstream of the throat;a reacting fluid flowing through the main passage;a feed material flowing through the feed passage to the main passage;a distributor that receives the feed material and distributes it annularly and approximately uniformly into contact with the reacting fluid in the main passage; andan expansion chamber to provide mixing of the feed material and the reacting fluid. 14. The nozzle reactor of claim 13 wherein the feed material includes heavy hydrocarbon material. 15. The nozzle reactor of claim 13 wherein the reacting fluid includes steam and/or natural gas. 16. The nozzle reactor of claim 1 wherein at least a significant portion of the expansion area is formed by the distributor. 17.
