Publication number: 20170291139Abstract: In a preferred embodiment, the invention relates to a process of sequestering carbon dioxide. The process comprises the steps of: (a) reacting a metal silicate with a caustic alkali-metal hydroxide to produce a hydroxide of the metal formerly contained in the silicate; (b) reacting carbon dioxide with at least one of a caustic alkali-metal hydroxide and an alkali-metal silicate to produce at least one of an alkali-metal carbonate and an alkali-metal bicarbonate; and (c) reacting the metal hydroxide product of step (a) with at least one of the alkali-metal carbonate and the alkali-metal bicarbonate produced in step (b) to produce a carbonate of the metal formerly contained in the metal silicate of step (a).Type: ApplicationFiled: June 28, 2017Publication date: October 12, 2017Applicants: UT-BATTELLE, LLC, UNIVERSITY OF TENNESSEE RESEARCH FOUNDATION, VIRGINIA MUSEUM OF NATURAL HISTORY FOUNDATIONInventors: James G. BLENCOE, Donald A. PALMER, Lawrence M. ANOVITZ, James S. BEARD

Patent number: 8152895Abstract: A process of producing magnesium metal includes providing magnesium carbonate, and reacting the magnesium carbonate to produce a magnesium-containing compound and carbon dioxide. The magnesium-containing compound is reacted to produce magnesium metal. The carbon dioxide is used as a reactant in a second process. In another embodiment of the process, a magnesium silicate is reacted with a caustic material to produce magnesium hydroxide. The magnesium hydroxide is reacted with a source of carbon dioxide to produce magnesium carbonate. The magnesium carbonate is reacted to produce a magnesium-containing compound and carbon dioxide. The magnesium-containing compound is reacted to produce magnesium metal. The invention also relates to the magnesium metal produced by the processes described herein.Type: GrantFiled: February 22, 2010Date of Patent: April 10, 2012Assignees: UT-Battelle, LLC, University of Tennessee Research Foundation, Virginia Museum of Natural History FoundationInventors: James G.
