Open the CIPO recordAbstract From the Canadian patent
A hydrocarbon fuel processing reactor for generating a hydrogen-enriched reformate from hydrocarbons is disclosed. A plurality of shells (36,46,56,66,76) are arranged coaxially having a gap defined between each of the successive shells, thereby forming a plurality of coaxial zones. The shells are configured to permit heat transfer from one zone to another. Fluid streams for reactions within the reactor are preheated by heat transfer from adjacent zones.

Why it's free to use
- Filed May 30, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 30, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
