Open the CIPO recordAbstract From the Canadian patent
The present invention is a novel process for methanol production in a liquid phase reactor from a synthesis gas comprising of hydrogen carbon dioxide and carbon monoxide. The liquid phase reactor contains a solid catalyst suspended in methanol. In this innovation methanol acts both as a product and as a suspension medium for the catalyst. The new innovation exploits the condensing conditions for methanol production. By operating at condensing conditions the methanol partial pressure at equilibrium is higher than the boiling pressure of methanol at the given temperature. Hence the produced methanal of the equilibrium composition condenses creating the potential of more gas to be converted. …

Why it's free to use
- Filed April 6, 2004 and granted June 5, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 6, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 6, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
