Abstract
Reaction schemes involving acids and bases; reactors comprising spatially varying chemical composition gradients (e.g., spatially varying pH gradients), and associated systems and methods, are generally described. For example, methods comprising producing an acid; dissolving a material comprising calcium in the acid to produce calcium ions; treating the calcium ions to produce solid calcium hydroxide and/or calcium oxide; and utilizing the solid calcium hydroxide and/or calcium oxide in a downstream process to produce a cement, wherein the downstream process comprises heating the solid calcium hydroxide and/or calcium oxide in a kiln are described.
