Lime and hydraulic cement manufacture by electrolysis using hyaloclastite or lava, carbon mineralization by hyaloclastite or lava electrolysis and method of making and using same
12534379 · 2026-01-27 ·

The invention comprises a method of making lime, dolomitic lime, hydraulic cement such as portland cement clinker and co-products such as pozzolan, acids, alumina, silica and the like. The method comprises providing a natural calcium-iron-aluminosilicate mineral from one or more of hyaloclastite, lava, scoria, volcanic glass, volcanic ash, or any other mineral of a basaltic or intermediate chemical composition and reacting the hyaloclastite with a first hydrochloric acid to create a first salt, precipitating the calcium ions to react with OH.sup. to form calcium hydroxide and heating the calcium hydroxide to create calcium oxide, alite and belite.

CO2 COLLECTION SYSTEM

A CO.sub.2 collection system is configured to collect CO.sub.2 by bringing CO.sub.2-containing gas into contact with a reaction liquid containing NaOH and stored in a reaction tank to produce a target product. The target product to be extracted from the reaction liquid is adjusted according to a maximum temperature of the reaction liquid after production of NaHCO.sub.3 in the reaction liquid, an extraction temperature that is a temperature of the reaction liquid when the target product is extracted from the reaction tank, and an initial concentration of the NaOH in the reaction liquid.

Lithium carbonate recovery process

A process for the recovery of lithium carbonate from a solution (1) containing a mixture of lithium sulfate and lithium hydroxide, the process comprising the precipitation of lithium carbonate (3) from the solution (1) containing a mixture of lithium sulfate and lithium hydroxide through the addition of carbon dioxide (2).

CRYSTALLIZER DEVICES AND RELATED SYSTEMS AND METHODS FOR DIRECT AIR CAPTURE OF CO2
20260131283 · 2026-05-14 ·

Crystallizer devices and methods of direct air capture of carbon dioxide are described herein. The methods include providing one or more polymeric strands in contact with an alkaline capture solution. Each of the polymeric strands is comprised of a plurality of polymeric fibers that combine to form an outer surface of the polymeric strand. The outer surface of the strand forms a crystallizing surface. The alkaline capture solution travels by way of capillary force from the outer surface of the strand inwardly through intra-strand pores and from a first end of the strand in a direction towards a second end of the strand through intra-strand pores. The methods also include, as the alkaline solution travels towards the second end, contacting the one or more polymeric strands with ambient air such that KOH within the alkaline solution reacts with CO.sub.2 to form K.sub.2CO.sub.3 precipitate at the crystallizing surface.
