MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617094339 A) filed by Bergen Carbon Solutions As on August 04, 2026, for Method And Apparatus For Purification And Separation Of Solid-State Carbon-Containing Material.
Inventors include Kostka, Vladimir; and Rosberg Hansen, Fredrik.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention relates to a method for purification and separation of solid-state carbon-containing material generated from electrolysis of a molten lithium carbonate elec- trolyte and recovery of lithium carbonate The method comprises obtaining a solid reaction product formed from electrolysis of a molten lithium carbonate salt electrolyte. The solid reaction product is mixed with an aqueous source and carbon dioxide is introduced at a predetermined first pressure to produce carbon dioxide treated aqueous reaction product mixture. The temperature and pressure of the carbon dioxide treated aqueous reaction product mixture is controlled to produce solid-state carbon material and an aqueous solu- tion rich in lithium salts. The solid-state carbon is separated from the aqueous solution rich in lithium salts. Carbon dioxide stream, precipitated lithium carbonate and an aqueous solution poor in lithium salts are generated by controlling the pressure and temperature of the aqueous solution rich in lithium salts. The precipitated lithium carbonate is separated from the aqueous solution poor in lithium salts. The method further comprises one or more of: recycling the recovered precipitated lithium carbonate as a feed source for the molten lithium carbonate salt electrolyte; and/or recycling the recovered aqueous solution poor in lithium salts as at least a portion of the aqueous source.
