Open the CIPO recordAbstract From the Canadian patent
Natural gas or other methane-containing feed gas is converted to a C5-C19 hydrocarbon liquid in an integrated system comprising an oxygenative synthesis gas generator a non-oxygenative synthesis gas generator and a hydrocarbon synthesis process such as the Fischer-Tropsch process. The oxygenative synthesis gas generator is a mixed conducting membrane reactor system and the non-oxygenative synthesis gas generator is preferably a heat exchange reformer wherein heat is provided by hot synthesis gas product from the mixed conducting membrane reactor system. Offgas and water from the Fischer-Tropsch process can be recycled to the synthesis gas generation system individually or in combination.

Why it's free to use
- Filed September 14, 1999 and granted September 30, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 14, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 14, 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.
