Abstract:
There are provided methods and systems for an electrochemical cell including an anode and a cathode where the anode is contacted with a metal ion that converts the metal ion from a lower oxidation state to a higher oxidation state. The metal ion in the higher oxidation state is reacted with hydrogen gas, an unsaturated hydrocarbon, and/or a saturated hydrocarbon to form products.
Abstract:
Provided are methods for sequestering carbon dioxide. A recovery method and system for recovering a gaseous component is provided. Methods and systems may utilize one or more absorbing solutions in two or more absorbing zones. Methods for reducing the volume of an absorbing system are described. Methods for adjusting the composition of sequestered carbon dioxide are provided.
Abstract:
Systems and methods for lowering levels of carbon dioxide and other atmospheric pollutants are provided. Economically viable systems and processes capable of removing vast quantities of carbon dioxide and other atmospheric pollutants from gaseous waste streams and sequestering them in storage-stable forms are also discussed.
