Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.

Hydrogen production from carbonaceous material

Hydrogen is produced from solid or liquid carbon-containing fuels in a two-step process. The fuel is gasified with hydrogen in a hydrogenation reaction to produce a methane-rich gaseous reaction product, which is then reacted with water and calcium oxide in a hydrogen production and carbonation reaction to produce hydrogen and calcium carbonate. The calcium carbonate may be continuously removed from the hydrogen production and carbonation reaction zone and calcined to regenerate calcium oxide, which may be reintroduced into the hydrogen production and carbonation reaction zone. Hydrogen produced in the hydrogen production and carbonation reaction is more than sufficient both to provide the energy necessary for the calcination reaction and also to sustain the hydrogenation of the coal in the gasification reaction. The excess hydrogen is available for energy production or other purposes. Substantially all of the carbon introduced as fuel ultimately emerges from the invention process in a stream of substantially pure carbon dioxide. The water necessary for the hydrogen production and carbonation reaction may be introduced into both the gasification and hydrogen production and carbonation reactions, and allocated so as transfer the exothermic heat of reaction of the gasification reaction to the endothermic hydrogen production and carbonation reaction.

Protein beverage and protein beverage concentrate and methods of making the same

An improved protein beverage which may provide a relatively high protein content, ranging from about 0.01% by weight to about 15% by weight, while optionally employing a carbonation concentration between about 0.1 volumes of carbonation (per volume of liquid drink) to about 6 volumes of carbonation. Preferably the protein is a protein, such preferably as whey protein, or others. The protein beverage may contain juice and / or an additive which provides energy generation enhancement. The protein beverage may be heat treated to inactivate pathogenic microbes in the presence of the carbonation which may be used to provide taste and mouth feel for the drink. Typically, the treatment for pathogenic microbe inactivation is carried out in the individual package used for storage and handling of the protein drink. The protein beverage may be prepared from a protein beverage concentrate, which may be in the form of a syrup concentrate or a powder concentrate.

Separation of Carbon Dioxide (Co2) From Gas Mixtures By Calcium Based Reaction Separation (Cars-Co2) Process

A reaction-based process has been developed for the selective removal of carbon dioxide (CO2) from a multicomponent gas mixture to provide a gaseous stream depleted in CO2 compared to the inlet CO2 concentration in the stream. The proposed process effects the separation of CO2 from a mixture of gases (such as flue gas / fuel gas) by its reaction with metal oxides (such as calcium oxide). The Calcium based Reaction Separation for CO2 (CaRS—CO2) process consists of contacting a CO2 laden gas with calcium oxide (CaO) in a reactor such that CaO captures the CO2 by the formation of calcium carbonate (CaCOa). Once “spent”, CaCO3 is regenerated by its calcination leading to the formation of fresh CaO sorbent and the evolution of a concentrated stream of CO2. The “regenerated” CaO is then recycled for the further capture of more CO2. This carbonation-calcination cycle forms the basis of the CaRS—CO2 process. This process also identifies the application of a mesoporous CaCO3 structure, developed by a process detailed elsewhere, that attains >90% conversion over multiple carbonation and calcination cycles. Lastly, thermal regeneration (calcination) under vacuum provided a better sorbent structure that maintained reproducible reactivity levels over multiple cycles.

Method of treating cement kiln dust for recovery and recycle

InactiveUS6331207B1SolubilityAmmonium compounds
Fresh or stockpiled cement kiln dust is moistened with sufficient water so that the amount of total free and combined water relative to dust is about 3 parts water to 1 part dust by mass, or less. The wet solids are treated with carbon dioxide to convert compounds, such as calcium hydroxide, to carbonates, such as calcium carbonate. The degree of carbonation is controlled so that the solubility of calcium becomes minimum for the dust being treated; this is also when hydroxyl and bicarbonate ions in solution are about at their minima. As the carbonation reactions occur, the water combined in hydroxides is released as free water so that the mixture becomes a slurry and the potentially soluble alkalies and sulfate (and any chlorides present) are released to the liquid phase. The solids are separated from the liquid, and the solids, which may be washed, provide a material suitable for return as feed to the kiln. The liquid, which contains the dissolved alkali compounds, is recycled to reclaim additional dust or treated to recover alkali salts when the alkali salts are sufficiently concentrated.While any source of carbon dioxide may be used, the preferred source is exit gases from the kiln. The gases are conditioned by condensation of water and removal of ammonium compounds, such as sulfate and chloride. The conditioning condensate may be treated to recover useful byproduct salts.

Additive for Carbonated Beverage

It is intended to provide a carbonated beverage excelling in function as thirst-quenching beverage and taste through strengthening or sustaining of carbonated feel peculiar to carbonated beverage (brisk intense stimulation and sensation at pass through the throat, brought about by carbon dioxide gas, and sensation of coolness (refreshing sensation) produced by a combination of carbon dioxide gas and flavor) which after opening, rapidly drops depending upon a combination of employed raw materials, such as fruit juice, sweetener, color additives and flavoring, and upon evaporation of carbon dioxide gas. The drop of carbonated feel brought about depending upon a combination of raw materials, such as fruit juice and sweetener, can be relieved by adding to a carbonated beverage an additive for carbonated beverage comprising spilanthol or a spilanthol-containing plant extract or plant essential oil as an active ingredient. Further, the addition would help inhibit drop of carbonated feel brought about depending upon evaporation of carbon dioxide gas after opening and would help retain the taste and function as function as thirst-quenching beverage inherently to be had by carbonated beverage even after opening.
