Open the CIPO recordAbstract From the Canadian patent
A Fischer-Tropsch catalyst is activated by a process comprising reducing the catalyst by contact with a hydrogencontaining gas, the hydrogen concentration and the space velocity of the gas contacting the catalyst increasing step-wise or continuously during the activation. The process may be employed to activate a fresh catalyst prior to its use or to regenerate an exhausted or partially exhausted catalyst. The catalyst once, activated, may be used in a process for the preparation of hydrocarbons from carbon monoxide and hydrogen.

Why it's free to use
- Filed August 18, 1992 and granted July 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
