  • Method for producing renewable fuels
    Patent number: 11046905
    Abstract: The present invention relates to production of renewable fuels and fuel components from plant oil originating from at least one Brassica species, where said Brassica species, doped with at least one nitrogen-fixing bacteria, is cultivated to obtain Brassica seed oil, and feedstock comprising the Brassica seed oil is converted in a converting step, whereby renewable fuel or renewable fuel components are obtained. The invention also relates to a method for reducing nitrate release in renewable fuel production. Further, the invention relates to a method for reducing greenhouse gases in renewable fuel production.
    Type: Grant
