Embodiment 1

[0058] This example shows a different method of the prior art using old carbon dioxide.

[0059] Test n°1

[0060] This test exemplifies the prior art and involves the production method of calcium carbonate precipitated by the reaction of lime and old carbon dioxide generated by the combustion of fossil energy sources such as butane.

[0061] To this end, the use of ground natural calcium carbonate (Omyapure from Omya SAS) TM ) After calcining in a muffle furnace at 900°C for 6 hours to produce calcium oxide CaO, the calcium oxide CaO is suspended in a water-containing vessel without carbon dioxide to form calcium hydroxide Ca(OH) 2 suspension.

[0062] Once the lime suspension is formed with a dry matter weight concentration equal to 10%, the old carbon dioxide generated by the combustion of butane using a camping gas burner is added to it at ambient temperature (22°C ± 2°C) until the pH value is about The strong alkaline value of 13 drops to a value of 8.0 to 8.5.

[0063] The p...

Embodiment 2

[0074] This example shows the method of the invention using fresh carbon dioxide.

[0075] Test n°4

[0076] This test exemplifies the present invention and relates to a method for producing calcium carbonate precipitated by the reaction of lime with fresh carbon dioxide produced by the combustion of ethanol obtained from the fermentation of organic compounds such as cherry wine.

[0077] To this end, the use of ground natural calcium carbonate (Omyapure from Omya SAS) TM ) After calcining in a muffle furnace at 900°C for 6 hours to produce calcium oxide CaO, the calcium oxide CaO is suspended in a water-containing vessel without carbon dioxide to form calcium hydroxide Ca(OH) 2 suspension.

[0078] At the same time, the cherry wine alcoholic beverage purchased from the supermarket was distilled from 37% by volume to 65% by volume, and then treated with sodium sulfate to absorb the remaining water and obtain an ethanol concentration of 97%.

[0079] Once the lime suspension is for...

Embodiment 3

[0131] This example exemplifies the pharmaceutical preparations of the present invention used to measure calcium carbonate from 14 C direction 12 C method of nuclear conversion rate.

[0132] Test n°13

[0133] This test exemplifies the existing technology, using Omya SAS and Omyapure TM It is a dry pharmaceutical preparation made of ground natural calcium carbonate powder sold under the name.

[0134] To this end, 30 mg of the test sample is placed in a 7-ml vial equipped with two continuous 14.7-ml reactors under a pressure of 250 mbar, thereby forming two continuous traps, the latter being a liquid nitrogen trap, and the second One is cooled to a temperature 20°C to 30°C higher than the second to prevent contamination by other volatile compounds from the sample.

[0135] Approximately 0.4 milliliters of hydrochloric acid was then poured into the vial, which then reacted with the drug formulation and released carbon dioxide, trapping it in a continuous trap.

[0136] Then by hyd...
