Definitions
- This invention relates to materials which are useful in removing CO 2 from gas. More particularly, it relates to mixed salt compositions which act as sorbents for the CO 2 , methods for making these materials and their uses. These adsorbents are useful for removing CO 2 from exhaust gas stream in both stationary and mobile applications, such as transportation vehicles, and so forth.
- CO 2 capture technologies are being developed for application to stationary sources of CO 2 . These sources include coal, and natural gas fired power plants, as well as processes for production of materials as diverse as cement and steel. This invention as described herein is useful in such applications, but also in mobile source applications.
- the invention relates to a mixed salt, solid sorbent composition which is useful in removing CO 2 from gases.
- the composition may be regenerated easily, and thus is useful in continuous scrubbing processes. Further, it is useful in removal of CO 2 from both mobile and stationary applications.
- An important feature of the invention is that it is useful in the removal of CO 2 from gas mixtures at ambient or near ambient pressures, and at temperatures ranging from about 50°C to about 400°C, with release of the CO 2 at temperatures of from about 150°C to about 500°C.
- the mixed salt sorbent compositions of the invention contain alkaline earth and alkali metals, in salt form and at a range of ratios relative to each other.
- the alkaline earth metal is represented by magnesium (Mg)
- the alkali metal is one of the "group IA" elements, i.e., Li, Na, K, or Rb.
- stationary applications includes coal, oil, and gas-fired power generating plants, steam boilers for commercial and industrial use, heat plants and other such installations that produce CO 2 from the combustion of hydrocarbon fuels.
- mobile sources includes internal combustion engines used to power all types of vehicles such as automobiles, trucks, buses, trains, boats, and airplanes that produce an exhaust gas stream containing CO 2 from the combustion of hydrocarbon fuels.
- This dry cake was then calcined by heating from 120°C to 450°C, at a ramp rate of 3°C/minute, followed by 450°C for 4 hours.
- the calcined cake was crushed and sieved to collect a 150-425 mesh fraction, which was then tested.
- the testing involved loading a packed bed reactor with 6g of the sorbent described supra, with inert SiC added to occupy any remaining volume.
- a conventional gas analyzer was used to measure the concentration of CO 2 leaving the reactor.
- the reactor was then activated by heating it to 450°C, at a rate of 10°C/minute, using a flow of N 2 and was held at this temperature until the concentration of CO 2 in the effluent dropped below 0.1 %.
- the reactor was cooled to the lowest adsorption temperature tested and then a simulated exhaust gas (13% CO 2 , 13% H 2 O, remainder N 2 ), was added to the reactor as a feedstream.
- the concentration of CO 2 in the gas effluent was measured continuously and the adsorption phase was continued, until the concentration of CO 2 in the effluent was 90% of the concentration in the feed gas, i.e., the "90% break through.”
- the feed gas was changed to pure N 2 , and its temperature was ramped at 5°C/minute to 450°C.
- the reactor itself was maintained at 500°C and until the effluent gas had a CO 2 concentration below 0.1% vol., or for 2 hours, so as to regenerate the sorbent.
- the reactor temperature was then decreased to the desired adsorption temperature, and the process was repeated.
- Figure 1 shows the amount of CO 2 loaded on the sorbent, over a temperature range of 200-425 °C, at 25°C increments.
- Mg(NO 3 ) 2 has significantly greater solubility in water than the other compounds.
- the differences in solubility also indicate that the final products result from different reactive mechanisms.
- the nitrate salt for example, participates in anion exchange with the sodium salts, whereas the oxide and hydroxide do not Hence, the more soluble the magnesium salt, the greater the adsorption ability of the final product.
- Mg(NO 3 ) 2 , MgCl 2 , Mg(CH 3 COO) 2 , and other highly soluble magnesium salts are thus preferred in making the sorbents of the invention.
- Sorbents were prepared, as described, supra, using Mg:Na molar ratios of 3:1 to 8:1, and were tested as described in these examples.
- the composition of the invention comprises a mixed salt of a magnesium compound, such as MgCC>3 or MgO, and at least one salt of a Group IA metal, wherein the molar ratio of Mg to the Group IA metal may range from 8:1 to 3:1, and is preferably from 6:1 to 4:1.
- the adsorbents are useful both in stationary and mobile applications for the removal of CO 2 from the exhaust gas stream and the recovery of substantially pure CO 2 that can be compressed for temporary storage pending its ultimate disposition. Following desorption of the CO 2 , the regenerated adsorbent can then be revised, without substantial loss in adsorbent capacity during a significant number of cycles.
- the magnesium compound is preferably MgO
- the at least one salt of a Group IA metal is preferably a carbonate, and/or a nitrate salt.
- An especially preferred composition of the invention is MgO:Na 2 CO 3 :NaNO 3 , where the molar ratio of Mg:Na is about 4.8. Salts of Li, , or Rb may replace the sodium salts in the preferred composition.
- the mixed salt sorbents of the invention can be made via, e.g., a gelation reaction, as in Example 1, or preferably a precipitation reaction.
- a magnesium salt and a Group IA metal salt are prepared in solution form, and combined to form a reactive mixture. This reaction may optionally be carried out with a precipitating agent.
- the salts are chosen such that, upon reacting with each other, MgO or MgCO 3 is formed in the precipitate.
- a highly soluble Mg compound is used, such as MgO itself, Mg(OH)2, or most preferably, Mg(NO 3 ) 2 .
- MgCl 2 or Mg(CH 3 COO) 2 may also be used.
- the sorbent powder can be made into an extrudate, either via adding a binder, such as boehmite, or via special preparative techniques known in the art, which result in a loss in sorbency; however, the technique is useful for keeping pressure drops low, in packed beds, and for rendering handling of the material easier.
- a binder such as boehmite
- the reaction is carried out with concentrations of the reactive salts which provide for a ratio of Mg:Group IA metal of from 3:1 to 8:1, most preferably from 4:1 to 6:1.
- concentrations of the reactive salts which provide for a ratio of Mg:Group IA metal of from 3:1 to 8:1, most preferably from 4:1 to 6:1.
- concentrations of the reactive salts which provide for a ratio of Mg:Group IA metal of from 3:1 to 8:1, most preferably from 4:1 to 6:1.
- concentrations of the reactive salts which provide for a ratio of Mg:Group IA metal of from 3:1 to 8:1, most preferably from 4:1 to 6:1.
- the choice of ratios is one left to the artisan because, as noted supra, by varying the ratio one produces sorbents with different properties. Knowing the conditions under which the sorbent will operate will determine the ratios employed.
- a precipitating agent may be added to facilitate the reaction, such as NaNO 3 .
- the precipitating agent is preferably a salt of a Group IA metal
- the invention also comprehends methods for removing CO 2 from a gas or gas mixture, such as an exhaust gas stream produced by the combustion of a hydrocarbon fuel, by contacting the gas or gas mixture with the mixed salt sorbent described supra, at a temperature which ranges from about 100°C to about 450°C, preferably from about 250°C to about 350°C, for a time sufficient for the sorbent to remove a portion of the CO 2 therefrom.
- the sorbent will become "saturated" by the CO 2 , and this can be detennined by measuring the content of CO 2 in gas after it has contacted the sorbent and comparing this value to the amount of CO 2 in the gas prior to the contact.
- the sorbent can be regenerated by indirect heat exchange, e.g., with the hot exhaust gas stream which is at an elevated temperature, e.g., about 500°C. Again, by measuring the amount of CO 2 which is contained in the exiting gas, the ordinary skilled artisan can determine when the sorbent has been regenerated and can be reused.
- the removed CO 2 can be compressed and temporarily stored on board the mobile source until it is removed for permanent disposition, such as underground storage.
- the CO 2 can be put to use in various ways.
- the process described herein, in addition to removing CO 2 results in the accumulation of condensed H 2 O.
- These two species can be fed into a reactor or other means for generating fuel which, in turn, can be used, e.g., to power the CO 2 producing system described herein.
- the fuel is not used as it is produced, it, also can be accumulated and stored for later use.
- the stored CO 2 can be used, e.g., as a refrigerant gas, and then channeled for cooling and/or air conditioning.
- the captured CO 2 gas released from the adsorbent can be reacted with the condensed water recovered from the exhaust gas stream to form a hydrogen-based fuel which can in turn be used, e.g., to power the ICE of the vehicle in which the CO 2 and H 2 O were produced.
- Any solar energy to which the vehicle or other mobile source was exposed can also be stored and used to facilitate this reaction.
- means can be provided in the system for cooling the CO 2 , thereby permitting its use as a coolant or refrigerant for use in the system.
