Description

  The present invention relates to an electrochemical cell for ammonia production, and more particularly to an anode-supported electrochemical cell (anode-supported electrochemical cell, ASC). Further, it is an ammonia synthesis method using the cell.

  It is notable that ammonia synthesis has traditionally established the Harbor Bosch method, which has become a raw material for fertilizers and a driving force for agricultural development as well as for the great development of the chemical industry. In the Harbor Bosch method, ammonia is obtained by reacting hydrogen and nitrogen under high pressure conditions of 400 to 600 ° C. and 20 to 40 MPa using a catalyst mainly composed of iron. As an industrial catalyst, a catalyst is used in which the catalytic performance of iron is improved by adding alumina and potassium oxide to iron (see Non-Patent Document 1). As another technique, there is an example in which a Ru-based catalyst is proposed (see Patent Document 1).

  The most recent problem is the technology to prevent resource depletion and global warming. The above-mentioned Harbor Bosch method uses so-called fossil resources as raw materials, and is a high-temperature and high-pressure process. Therefore, it consumes a lot of energy in its manufacturing process and uses a large amount of resources to produce a large amount of global warming gas. To be discharged. Instead of this technology, it is desired to propose more sustainable technology by effectively utilizing limited resources on the earth.

  From such a background, as one of the new methods for synthesizing ammonia, proton conductive oxide is used as a solid electrolyte, hydrogen and nitrogen or water vapor and nitrogen are supplied, and further, voltage is applied to the cell, thereby ammonia. Have been proposed (Patent Documents 3 and 4, Non-Patent Document 2). In the method of electrolytic synthesis of ammonia described in Patent Document 2, a method of synthesizing ammonia from water vapor and nitrogen is disclosed, and there is no need to produce hydrogen gas using hydrocarbons unlike the Harbor Bosch method. There is no problem of discharging a large amount of carbon dioxide.

  In the ammonia electrosynthesis using proton conductive oxide as a solid electrolyte, hydrogen or water vapor is generated at the anode by the anode catalyst to generate protons and electrons (reaction formula (1)), and the protons pass through the solid electrolyte membrane and then protons at the cathode. And nitrogen proceed as shown in (Reaction Formula 2). In order for the reactions of (Reaction Formula 1) and (Reaction Formula 2) to proceed further, it is necessary to increase the ionic conductivity in addition to enhancement of the functions of the anode and cathode catalyst. To increase ionic conductivity, it is effective to increase the reaction temperature. However, because ammonia is in an equilibrium relationship between hydrogen and nitrogen, if the reaction temperature is increased, the generated ammonia is decomposed into nitrogen and hydrogen. The reaction is promoted. For this reason, it is preferable to carry out the reaction at a lower temperature, but when the temperature is lowered, the ionic conductivity of the solid electrolyte membrane is lowered. In order to ensure ionic conductivity in a low temperature region, it is important to reduce the thickness of the solid electrolyte.

  One of the structures of an electrochemical cell using a solid electrolyte membrane is an electrolyte-supported electrochemical cell in which an anode is provided on one side of the solid electrolyte and a cathode is provided on many sides. In such an electrochemical cell, since the solid electrolyte membrane serves as a support, the solid electrolyte membrane is required to have strength. If the solid electrolyte membrane as a support is made too thin, the strength of the cell is reduced and cracking tends to occur, so there is a limit to thinning the electrolyte-supported electrochemical cell.

As a result of intensive studies in view of the above problems, the inventors have been able to reduce the thickness of the solid electrolyte, and by applying an electrode-supported electrochemical cell using an anode support that can ensure strength, this is a known technique. It has been found that ammonia can be obtained electrochemically efficiently from an electrolyte-supported electrochemical cell, and the invention has been completed.

  In the present invention, it is possible to synthesize ammonia more efficiently than a conventional electrolyte support cell by applying a voltage to an anode support cell using a proton conductive oxide as an electrolyte. Moreover, renewable energy such as solar energy can be used as the electrical and thermal energy necessary for the synthesis method.

It is a conceptual diagram of the electrochemical cell of this invention. It is a conceptual diagram of the electrochemical cell of this invention. It is a conceptual diagram of the reactor used by this invention.

  The present invention is specified as follows.

  Electrochemistry used to obtain ammonia from a hydrogen-containing gas or water vapor-containing gas and a nitrogen-containing gas, characterized in that an anode is arranged on one side of the proton conductive solid electrolyte and a cathode is arranged on the other side and supported by the anode. Preferably, the anode is a porous body composed of a conductive component (A) and a skeleton component (B), and the conductive component (A) contains an oxide having electronic conductivity. The anode is a porous body composed of a conductive component (A) and a skeleton component (B), and the skeleton component (B) is selected from the group consisting of 2A group to 4B group It is an oxide containing an element, and the thickness of the proton conductive solid electrolyte is 1 to 50 μm.

  Furthermore, using the electrochemical cell, a voltage is applied between the anode and the cathode, a hydrogen-containing gas or a water vapor-containing gas is introduced to the anode side, a nitrogen-containing gas is introduced to the cathode side, and converted to ammonia. This is an ammonia synthesis method.

  Hereinafter, an embodiment of a cathode-supported electrochemical cell and a synthesis method used in the ammonia synthesis method of the present invention will be described with reference to the drawings. 1 and 2 are examples of a cross-sectional view of an electrochemical cell using the method of the present invention, and FIG. 3 is an example of an apparatus using the method of the present invention.

(Anode support)
In FIG. 1, reference numeral 1 denotes an anode support, which is a porous body composed of a conductive component (A) and a skeleton component (B). An oxide in which the conductive component (A) has electronic conductivity can be used.

The conductive component (A) is a component that can conduct electricity when a voltage is applied, and any component having the effect can be used. The skeletal component (B) has an action of maintaining the strength of the anode support, and any skeleton component (B) may be used as long as it has the action. More specifically, a preferable material of the conductive component (A) is an oxide having an electronic conductivity having a perovskite structure represented by ABO 3, and the A site is composed of an alkaline earth metal element, La, Y, and Sc. A material including at least one selected from the group, and the B site including at least one selected from the group consisting of Ti, Nb, V, Ta and Co, for example, SrTiO 3 , La 1-x Sr x TiO 3 (x = 0.6~0.95) , Sr 1-x Y x TiO 3 (x = 0.05~0.2), Sr 1-x Y x Ti 1-y Co y O 3 ( x = 0.05 to 0.2, y = 0.03 to 0.1), Sr x Ti 1-y M y O 3 (M = Nb, V, Ta, x = 0.8 to 1.0, y = 0.05 to 0.15) can be used.

As the skeletal component (B), a proton conductive oxide, a ceria-rare earth oxide solid solution, or a ceria-alkali earth metal oxide solid solution containing an alkaline earth metal element and a tetravalent transition metal of group IVA to IVB is used. For example, a perovskite oxide having an ABO 3 type structure, wherein the A component is an alkaline earth metal, the B component is a tetravalent transition metal of group IVA to IVB, La, Pr, Nd, Sm, Gd Yb, Sc, Y, In, Ga, Fe, Co, Ni, Zn, Ta or Nb-doped oxide, yttria doped ceria, samaria doped ceria, gadria doped ceria, calcia doped ceria or strontia doped ceria Etc. can be used.

  The thickness of the anode serving as the support can be changed according to the specifications. For this reason, 200-2000 micrometers is preferable and, as for the thickness of the anode used as a support body, More preferably, it is 300-1000 micrometers. If the anode is too thin, the strength of the cell may be reduced. If the cathode is too thick, gas diffusion is insufficient and cell performance is degraded.

  The structure of the anode serving as the support is a porous body, and the porosity is preferably 20 to 60%, for example. If it is less than 20%, gas diffusion and active sites may decrease, and ammonia production efficiency may decrease. When it is 60% or more, the sintered density is decreased, and the strength of the support is decreased.

(Anode catalyst)
An anode catalyst is a catalyst that can decompose hydrogen or water vapor to generate protons. By using the anode catalyst, protons can be generated more efficiently than simply using the conductive component. The anode catalyst is preferably at least one of Pt, Pd, Ru, Rh, Ir, Ni, Co, Fe, Cu, Ag, Mn, Nb, Ta, La, Ce, Pr, Nd, Sm, or alkaline earth The metal or alloy containing the oxide or the oxide comb may contain a sulfide. Further, as shown in FIG. 2, an anode catalyst layer that decomposes hydrogen or water vapor to generate protons may be provided on the support.

(Solid electrolyte)
The solid electrolyte is a medium for transferring protons from the anode to the cathode, and the material of the solid electrolyte that can be used in the present invention is an oxide exhibiting proton conductivity, for example, an ABO 3 type structure. Perovskite-type oxides having a structure, pyrochlore-type oxides having a structure of A 2 B 2 O 7 type, ceria-rare earth oxide solid solution or ceria-alkali earth metal oxide solid solution, oxides having a brown mirrorite structure, etc. Can be used. Preferably, a perovskite oxide having an ABO 3 type structure, wherein the A component is an alkaline earth metal, the B component is a tetravalent transition metal of group IVA to IVB, La, Pr, Nd, Sm, Gd, Yb , Sc, Y, In, Ga, Fe, Co, Ni, Zn, Ta or Nb.

  The thickness of the solid electrolyte is 1 to 50 μm, preferably 1 to 30 μm, and more preferably 1 to 20 μm. A thickness of 1 μm or less is difficult to produce by an industrial process such as screen printing, so it is not practical, and if the electrolyte is thicker than 50 μm, the ionic conductivity decreases and the ammonia generation efficiency decreases. It is not preferable.

(Cathode catalyst)
The cathode includes a material that synthesizes ammonia by reaction of protons generated and transported with the protons and nitrogen molecules. For example, Ru, Ir, Ag, Pd, Ni, Co, Fe, Ti, Cu Zn, Mn, Mo, Sn, In, W, Nb, Ta, La, Ce, Pr, Nd, or Sm At least one metal or alloy, oxide, or sulfide can be used.

(Ammonia synthesis method)
The gas to be introduced into the anode used in the present invention may be any gas as long as it contains hydrogen or water vapor. However, when hydrogen gas is used as a hydrogen source used when ammonia is synthesized, Is 90 to 99% by volume, more preferably 95 to 99% by volume, and the other gas such as hydrogen may be any gas as long as it is inert to the reaction at the anode, such as water vapor or argon. is there.

  Moreover, when using water vapor | steam as a hydrogen source used when synthesize | combining ammonia, it is 40 to 97 volume%, More preferably, it is 50 to 97 volume%. The other gas such as water vapor may be any gas as long as it is inert to the reaction at the anode, such as oxygen and argon.

  The gas to be introduced into the cathode used in the present invention may be any as long as it contains nitrogen, but the gas preferably contains 90 to 100% by volume, more preferably 95 to 100% nitrogen. It is included in volume%. The other gas such as nitrogen may be any gas as long as it is inert to the reaction at the cathode, such as water vapor, hydrogen, and argon.

  Further, the gas discharged from the cathode contains ammonia, and the exhaust gas can be used for other purposes as it is, and ammonia can be purified.

  The gas discharged from the anode or the cathode can be reused as each introduced gas.

  As the voltage applied to the cell, the higher the voltage, the faster the generation rate of ammonia, but the lower the reaction rate between transported protons and nitrogen. Moreover, it is not preferable to apply a high voltage because energy efficiency is lowered. For this reason, the voltage applied between the cells is preferably 3 V or less.

  Hereinafter, the present invention will be described in detail with reference to examples and comparative examples, but the present invention is not limited to the following examples unless it is contrary to the gist of the present invention.
