Abstract
Described herein is a soda magcite composition, methods of manufacture of soda magcite compositions and use of soda magcite for carbon dioxide sequestration. The soda magcite composition comprises a mixture of magnesium hydroxide, metal hydroxide and water to create a composition that is highly effective at sequestering carbon dioxide.
Claims32
A magnesium based hydrate composition comprising a mixture of:
- 60-90% by weight of magnesium hydroxide containing material;
- 0.1-20% by weight of metal hydroxide selected from:
- NaOH, LiOH or KOH, Ca(OH)2, and combinations thereof;
- and
- greater than 5% water;
- wherein the magnesium based hydrate composition is configured to catalyse sequestration of carbon to the magnesium hydroxide containing material.
A magnesium based hydrate composition comprising a mixture of:
- 60-90% by weight of magnesium hydroxide containing material;
- silica containing materials, the silica containing material comprising less than approximately 50% by weight of the magnesium based hydrate composition;
- greater than 5% water;
- wherein the magnesium based hydrate composition is configured to catalyse sequestration of carbon to the magnesium hydroxide containing material.
The magnesium based hydrate composition as claimed in claim 18 further comprising 5-20% by weight inert materials selected from:
- carbonates, silicates, oxides, sulphates and combinations thereof.
A magnesium based hydrate composition comprising a mixture of:
- 60-90% by weight of magnesium hydroxide containing material;
- 5-20% by weight inert materials selected from:
- carbonates, silicates, oxides, sulphates and combinations thereof, these inert materials configured to increase overall porosity of the magnesium hydroxide containing material;
- greater than 5% water;
- wherein the magnesium based hydrate composition is configured to catalyse sequestration of carbon to the magnesium hydroxide containing material.
A soda magcite composition comprising:
- magnesium hydroxide;
- metal hydroxide;
- and
- water.
