Definitions

  • the invention relates generally to the reversible adsorption of carbon dioxide from a gas mixture, and more particularly to the reversible adsorption of carbon dioxide from ambient air.
  • Carbon dioxide has been identified as a major contributor to climate change.
  • the present invention addresses these problems by providing a solid material capable of reversibly adsorbing carbon dioxide, said solid material comprising a porous carrier material having deposited thereon: (i) a salt capable of reacting with carbon dioxide; and optionally (ii) a particulate, water-insoluble inorganic material.
  • Another aspect of the invention comprises a process for recovering carbon dioxide from a carbon dioxide containing gas mixture comprising (a) at a first temperature T 1;
  • Figure 1 is a schematic representation of a test set-up for determining the carbon dioxide absorption properties of solid materials.
  • Figure 2 is a graph plotting the carbon dioxide desorption rates as a function of temperature for various solid materials tested in the set-up of Figure 1.
  • Figure 3 is a representation of carbon dioxide loadings of various solid materials tested in the set-up of Figure 1.
  • Figure 4 is a schematic representation of an absorption/desorption device for carbon dioxide and water.
  • Figure 5 shows the device of Figure 4 in its absorption and desorption modes.
  • Figure 6 shows the desorption of carbon dioxide from a solid material, as a function of the desorption temperature.
  • reversibly adsorbing carbon dioxide means adsorption of carbon dioxide to a material that releases the adsorbed carbon dioxide at a temperature below 200 °C.
  • the present invention relates to a solid material capable of reversibly adsorbing carbon dioxide, said solid material comprising a porous carrier material having deposited thereon: (i) a salt capable of reacting with carbon dioxide; and optionally (ii) a particulate, water-insoluble inorganic material.
  • the temperatures of adsorption and desorption are very important for the economics of the process.
  • the solid material is preferably used in a temperature swing reaction. Large temperature swings require large energy inputs. In addition, large temperature swings tend to cause deterioration of adsorbent materials.
  • the solid material is capable of adsorbing carbon dioxide at a first temperature T and of desorbing carbon dioxide at a second temperature T 2 , such that T 2 > Ti and ⁇ , defined, as T 2 minus Ti is less than 200 °C.
  • T 2 > Ti and ⁇ defined, as T 2 minus Ti is less than 200 °C.
  • Equations (1) and (2) illustrate an important feature of this embodiment of the invention.
  • the adsorption reaction consumes water, which is released during the desorption reaction.
  • Water needed for the adsorption reaction is typically abundantly present in the gas mixture from which carbon dioxide is being adsorbed. Flue gases are, for example, produces by burning a fossil fuel of the general formula C n H 2n+2 , the flue gas contains carbon dioxide and water in close to a 1: 1 molar ratio.
  • Cold, dry air of 5 °C and 25% relative humidity contains about 0.15 mole/kg water. In all three cases there is more than enough water in the gas mixture for the adsorption reaction. In fact, it may be necessary to pre-dry the gas mixture prior to contacting it with the solid adsorbent material.
  • Equation (2) water adsorbed from the gas mixture (flue gas or ambient air) is released during the desorption reaction.
  • the adsorption/desorption process also provides water, which may be used in a subsequent C0 2 conversion reaction, or may be used in agriculture, for household use in washing and cleaning, or as a source of potable water.
  • the porous carrier material may be a honeycomb monolith material, for example of the kind as is used in catalytic converters for the treatment of exhaust gases of internal combustion engines.
  • the carrier may be made of a ceramic material, such as codierite; of a zeolite material; activated carbon; and the like.
  • the porous carrier material is made of a ceramic foam.
  • porous carrier material is activated carbon having a specific surface area in the range of from 150 m 27g to 600 nr 2/ g.
  • the solid material contains, in addition to the porous carrier material and the reactive salt, a particulate, water-insoluble inorganic material.
  • this material is an inorganic oxide having a specific surface area of less than 100 m 2/ g.
  • the material may be derived from a corresponding material having a specific surface area in excess of 100 m 2/ g by calcination or steam calcination.
  • suitable materials include alumina, silica, titania, zirconia, ceria, clay, zeolite, layered hydroxide material, hydrotalcite, and mixtures thereof.
  • a particularly preferred example is titania.
  • Another aspect of the present invention is a process for recovering carbon dioxide from a carbon dioxide containing gas mixture comprising (a) at a first temperature T 1;
  • the gas mixture further comprises water, such that the carbon
  • the gas mixture can be atmospheric air. It may be desirable to pre-dry atmospheric air prior to contacting it with the solid material, to adjust the carbon/dioxide/water molar ratio to within the range of from 1: 1 to 1:2.
  • the adsorption temperature T ⁇ is preferably less than 40 °C, more preferably less than 30 °C.
  • the desorption temperature T 2 is preferably less than 120 °C, more preferably less than 100 °C.
  • T 2 is a range of temperatures at which the desorption reaction takes place. It may be desirable to increase the temperature T 2 in the course of the desorption step. For example, in the case of potassium bicarbonate on activated coal the desorption reaction can be initiated at 40 °C, then slowly increased during the desorption step to 180 °C. In this example the temperature T 2 is 40 to 180 °C, and ⁇ is 160 °C or less. A significant portion of the absorbed C0 2 is desorbed at temperatures below 100 °C.
  • the solid material can be purged during the desorption step with an inert gas, such as nitrogen or dry steam.
  • an inert gas such as nitrogen or dry steam.
  • Preparation procedure of monoliths Two basic preparation procedures have been employed in the development of the C0 2 absorption monoliths.
  • the first procedure was aimed at creating a wash coat- like layer in the channels of a monolith made of a material that has a low porosity.
  • the second procedure was aimed at impregnating a highly porous monolith material.
  • a suspension of an insoluble inert carrier for example Ti0 2
  • a salt for C0 2 absorption for example K 2 CO 3
  • demineralized water demineralized water
  • the mass ratios of inert: salt:demi water was used in various compositions in the range of 1: 1:5 up to 2: 1 : 1.
  • the main determining factor for the demi water content was the pore size of the monoliths to be wash coated (a lower demi water content gives a thicker solution).
  • the suspension was used to wash coat the inert monoliths, after which the monoliths were dried in an oven to remove the demi water.
  • a 2 hour exposure time resulted in the maximum CO 2 concentration (ppm) desorbed being less than 40000 ppm, about 38500- 39000ppm.
  • the maximum CO 2 concentration desorbed was about 47000 ppm.
  • the maximum CO 2 concentration desorbed was about 49000 ppm.
  • the maximum CO 2 concentration desorbed was about 49500 ppm.
  • the maximum CO 2 concentration desorbed was about 50000 ppm.
  • the maximum CO 2 concentration desorbed was just under 50000 ppm, indicating that the exposure time at which most CO 2 is desorbed is above 14 hours.
  • FIG 3 the total amount of CO 2 released as a function of absorbent exposure time to airflow is shown. This is shown for three samples of monoliths: a sample that was not impregnated, a sample that was impregnated with a 1 :20 solution of potassium carbonate (by mass) and a sample that was impregnated with a 1: 10 solution of potassium carbonate (by mass). It can be seen that unimpregnated samples do not absorb CO 2 . The samples impregnated with the 1: 10 solution impregnation absorbed more CO 2 than the 1:20 impregnation. Furthermore the absorber appears to be saturated after an exposure to air of approximately 8 hours. After this time the amount of absorbed CO 2 no longer increased.
  • the absorbent material is used for capturing carbon dioxide and water from air in arid regions, such as deserts. As illustrated above in paragraph [0021] even dry air contains more than enough moisture for the adsorption reaction.
  • deserts are characterized by large temperature differences between daytime and night time.
  • a column filled with absorbent material will absorb water and carbon dioxide from cold desert air during the night. During the day the heat of the sun will raise the temperature of the column high enough to cause the water and carbon dioxide to desorb. Desorbed water and carbon dioxide can be stored in a storage vessel. Both can be used in a greenhouse to supply growing plants with two essential ingredients for the photosynthetic process.
  • the need for water in this embodiment is greater than the need for carbon dioxide.
  • the column can be partly filled with a desiccant, such as silica gel, and partly with the absorbent material of the invention.
  • the desiccant can be placed upstream or downstream from the C0 2 absorbent.
  • air can be forced through the column by mechanical means, such as a fan. It is possible also to use the natural temperature differences for creating the required air flow. This is illustrated in Figures 4 and 5.
  • Figure 4 shows a column 10, containing absorbent material.
  • Column 10 preferably has a rectangular cross section, with a heat capturing surface 11 preferably having an orientation for optimum solar exposure, i.e., a predominantly southern exposure in the northern hemisphere, or a predominantly northern exposure in the southern hemisphere.
  • FIG 10 can be closed at the bottom with bottom plate 12, and at the top with desorption head 13.
  • Figure 4 shows the column in its open configuration.
  • solar collector 14 captures solar heat, which heats op oil present in solar collector 14.
  • Expansion of the oil caused by the increase in temperature raises the pressure in solar collector 14 and oil lines 15 and 16.
  • the oil pressure is used to move bottom plate 12 and desorption head 13 to their closed positions.
  • the temperature of the oil drops, the oil pressure drops, and bottom plate 12 and desorption head 13 move to their open positions.
  • Figure 5 shows, on the left hand side, column 10 in its night time (open)
  • FIG 10 in the right hand portion of Figure 5 shows the daytime (closed) configuration. Column 10 and its contents are heated up by the sun. This effect is amplified by having heat exchange surface 11 oriented to the sun. Although the ambient temperature rarely exceeds 40 °C (measured in the shade), the temperature of the absorbent material inside column 10 may reach or even exceed 100 °C. Water and carbon dioxide absorbed to the absorbent material are desorbed at these temperatures.
  • Storage vessel 17 may be located in a cool place, for example underground. The temperature difference between column 10 and storage vessel 17 reinforces the gas flow. Moreover, a significant portion of the desorbed water collected in storage vessel 17 is condensed to liquid water.
  • column 10 is not purged when it changes over from absorption mode to desorption mode.
  • storage vessel contains air components, such as nitrogen and oxygen, in addition to carbon dioxide and water. If the contents of storage vessel are to be used in a greenhouse for growing plants, the presence of oxygen and nitrogen is of course not harmful.
  • the desorption behavior of an exemplary absorbent material was determined in the following experiment.
  • the absorbent material was an active carbon honeycomb, impregnated with K 2 CO 3 .
  • the material was saturated with carbon dioxide by prolonged exposure to air. Then the material was flushed with nitrogen, while the temperature was increased in steps of 20 °C. After each temperature increase the temperature was kept constant until no carbon dioxide was detectable anymore in the nitrogen flow leaving the absorbent bed.

Abstract

La présente invention concerne un matériau solide permettant d'adsorber de manière réversible du dioxyde de carbone. Le matériau comprend un matériau de support poreux. Un sel, susceptible de réagir au contact du dioxyde de carbone, est déposé sur le matériau de support. Facultativement, le matériau solide contient en outre un matériau inorganique particulaire insoluble dans l'eau. Le matériau peut être utilisé dans un procédé de récupération de dioxyde de carbone à partir d'un mélange de gaz contenant du dioxyde de carbone. Le mélange de gaz peut être de l'air atmosphérique. Le procédé comprend une modulation de la température entre une température d'adsorption (T1) et une température de désorption (T2). La différence entre (T2) et (T1) est inférieure à 200 °C.
