Abstract
Edible organic compounds which can serve as food or feed, or as components of food or feed, are synthesized from oxidized carbon and water, through the input of energy, and using well-known and validated synthesis pathways, leading to free fatty acids and optionally esterified to triglycerides. The source of carbon is preferably CO2 from the atmosphere, or more preferably point sources of CO2 from industry and/or energy production.
Claims18
A method for the production of edible organic substances, said method comprising the steps
- electrolysis of water to produce hydrogen and oxygen,
- capture or recovery of carbon dioxide,
- conversion of said carbon dioxide to carbon monoxide,
- subjecting said hydrogen and carbon monoxide to a Fischer-Tropsch synthesis to produce a mixture of olefins,
- optionally increasing the proportion of ethylene by coupling of methane to form ethylene, and/or converting higher olefins to form ethylene,
- isolating ethylene,
- synthesizing alpha-olefins or fatty acid alcohols from said ethylene, and
- oxidizing said alpha-olefins or fatty acid alcohols to free fatty acids with an even number of carbon atoms,
- wherein the net energy input is in the form of electricity.
