Abstract
Chemical reaction devices involving acid and/or base, and related systems and methods, are generally described.
Claims20
A method, comprising:
- producing an acid and a base via electrolysis;
- dissolving a material comprising calcium and silicon using the acid to produce ions comprising calcium in a region with a pH of 6 or less;
- precipitating calcium hydroxide from the ions comprising calcium using the base in a region with a pH of 10 or higher;
- and
- forming a cement with the calcium hydroxide.

A method, comprising:
- electrolytically forming a dihalide and hydrogen gas in a first reactor;
- reacting the dihalide with the hydrogen gas to form a hydrogen halide in a second reactor;
- dissolving the hydrogen halide in water to form an acid;
- dissolving a material comprising calcium and silicon using the acid to produce ions comprising calcium in a region with a pH of 6 or less;
- precipitating calcium hydroxide from the ions comprising calcium using a base in a region with a pH of 10 or higher;
- and
- forming a cement with the calcium hydroxide.
