Open the CIPO recordAbstract From the Canadian patent
A process for producting substantially pure hydrogen by contacting a stream of a hydrocarbon gas with a nickel containing catalyst in a membrane reactor. The membrane reactor combines a hydrogen permeable membrane and a catalyst capable of producing hydrogen via the direct cracking of hydrocarbons. The stream of a hydrocarbon gas is contacted with the catalyst at a temperature in the range of about 400 to 900 ~C which results in the conversion of the gas to substantially pure hydrogen, which selectively permeates through the membrane wall.

Why it's free to use
- Filed February 19, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 19, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
