Abstract

The embodiments of the present disclosure relate to a method and compounds for capturing and releasing carbon dioxide. The method comprises heating, and/or pressurizing, or electrolyzing a carbon capture compound that comprises beryllium in order to reduce a carbon dioxide content of a carbon dioxide containing gas.

First claim

We claim:

1 . A method for capturing and releasing carbon dioxide comprising:
(a) heating a beryllium carbonate containing compound to form a lower carbon dioxide content compound and releasing a first carbon dioxide containing gas; (b) cooling the lower carbon dioxide content compound in a presence of a second carbon dioxide containing gas to reform the beryllium carbonate containing compound; and (c) cycling step b to capture carbon dioxide from the second carbon dioxide containing gas, wherein the first carbon dioxide containing gas has a higher carbon dioxide content than the second carbon dioxide containing gas, and (d) facilitating step (b) by one or more of:
(i) forming a liquid aerosol of the molten beryllium carbonate and/or beryllium oxide and combining with the second carbon dioxide containing gas;
(ii) forming a powder or solid aerosol of the molten beryllium carbonate and/or the beryllium oxide and combining with the second carbon dioxide containing gas;
(iii) fixing the beryllium carbonate and/or the beryllium oxide to a high surface membrane or aerogel and combining with the second carbon dioxide containing gas; or
(iv) reacting the second carbon dioxide containing gas with a compound that comprises ammonium for making an ammonium carbonate and reacting a beryllium sulfate made by combining the beryllium carbonate and/or the beryllium oxide with a sulfate containing compound, then reacting the ammonium carbonate with the beryllium carbonate.

2 . The method of claim 1 , wherein the beryllium carbonate containing compound comprises (BeO) x ·(BeCO 3 ) y wherein x is 0 or higher than 0 and wherein y is greater than 0.

3 . The method of claim 1 , wherein the beryllium carbonate containing compound comprises an alkali carbonate, an alkali earth carbonate or any combination thereof.

4 . The method of claim 1 , wherein the beryllium carbonate containing compound comprises a salt that comprises one or more elements from column 4, 5, 6 or 7 from the periodic table of elements.

5 . The method of claim 1 , wherein the beryllium carbonate containing compound is a binary, ternary, quaternary or higher component mix of beryllium carbonate or beryllium oxide with at least one of an alkali carbonate, an alkali earth carbonate, or a salt that comprises an element from column 4, 5, 6 or 7 of the periodic table of elements.

6 . A method for capturing and releasing carbon dioxide comprising:
(a) depressuring a beryllium carbonate containing compound to form a lower carbon dioxide content compound and releasing a first carbon dioxide containing gas; (b) pressurizing the lower carbon dioxide content compound in a presence of a second carbon dioxide containing gas to reform the beryllium carbonate containing compound; and (c) cycling step b to capture carbon dioxide from the second carbon dioxide containing gas, wherein the first carbon dioxide containing gas has a higher carbon dioxide content than the second carbon dioxide containing gas, and (d) facilitating step (b) by one or more of:
(i) forming a liquid aerosol of the molten beryllium carbonate and/or beryllium oxide and combining with the second carbon dioxide containing gas;
(ii) forming a powder or solid aerosol of the molten beryllium carbonate and/or the beryllium oxide and combining with the second carbon dioxide containing gas;
(iii) fixing the beryllium carbonate and/or the beryllium oxide to a high surface membrane or aerogel and combining with the second carbon dioxide containing gas; or
(iv) reacting the second carbon dioxide containing gas with a compound that comprises ammonium for making an ammonium carbonate and reacting a beryllium sulfate made by combining the beryllium carbonate and/or the beryllium oxide with a sulfate containing compound, then reacting the ammonium carbonate with the beryllium carbonate.

7 . The method of claim 6 , wherein the beryllium carbonate containing compound comprises xBeO·y(BeCO 3 ) wherein x is 0 or higher than 0 and wherein y is greater than 0.

8 . The method of claim 6 , wherein the beryllium carbonate containing compound comprises an alkali carbonate, an alkali earth carbonate or any combination thereof.

9 . The method of claim 6 , wherein the beryllium carbonate containing compound comprises a salt that comprises one or more elements from column 4, 5, 6 or 7 of the periodic table of elements.

10 . The method of claim 6 , wherein the beryllium carbonate containing compound is a binary, ternary, quaternary or higher component mix of beryllium carbonate or beryllium oxide with at least one of an alkali carbonate, an alkali earth carbonate, or a salt that comprises an element from column 4, 5, 6 or 7 of the periodic table of elements.

11 . A method for capturing and releasing carbon dioxide comprising:
(a) depressuring and heating a beryllium carbonate containing compound to form a lower carbon dioxide content compound and releasing a first carbon dioxide containing gas; (b) pressuring and cooling the lower carbon dioxide content compound in a presence of a second carbon dioxide containing gas to reform the beryllium carbonate containing compound; and (c) cycling step b to capture carbon dioxide from the second carbon dioxide containing gas, wherein the first carbon dioxide containing gas has a higher carbon dioxide content than the second carbon dioxide containing gas, and (d) facilitating step (b) by one or more of:
(i) forming a liquid aerosol of the molten beryllium carbonate and/or beryllium oxide and combining with the second carbon dioxide containing gas;
(ii) forming a powder or solid aerosol of the molten beryllium carbonate and/or the beryllium oxide and combining with the second carbon dioxide containing gas;
(iii) fixing the beryllium carbonate and/or the beryllium oxide to a high surface membrane or aerogel and combining with the second carbon dioxide containing gas; or
(iv) reacting the second carbon dioxide containing gas with a compound that comprises ammonium for making an ammonium carbonate and reacting a beryllium sulfate made by combining the beryllium carbonate and/or the beryllium oxide with a sulfate containing compound, then reacting the ammonium carbonate with the beryllium carbonate.

12 . The method of claim 11 , wherein the beryllium carbonate containing compound comprises xBeO·y(BeCO 3 ) wherein x is 0 or higher than 0 and wherein y is greater than 0.

13 . The method of claim 11 , wherein the beryllium carbonate containing compound comprises an alkali carbonate, an alkali earth carbonate or any combination thereof.

14 . The method of claim 11 , wherein the beryllium carbonate containing compound comprises a salt that comprises one or more elements from column 4, 5, 6 or 7 from the periodic table of elements.

15 . The method of claim 11 , wherein the beryllium carbonate containing compound is a binary, ternary, quaternary or higher component mix of beryllium carbonate or beryllium oxide with at least one of an alkali carbonate, an alkali earth carbonate, or a salt that comprises an element from column 4, 5, 6 or 7 of the periodic table of elements.
