Definitions
- the present invention relates to a method for generating hydrogen gas, which is expected to be used as a fuel for a next-generation energy source, particularly a fuel cell, from water by direct thermal decomposition.
- Hydrogen is characterized as a high-quality energy source due to its physical and chemical properties, as the only product of combustion is water. It is also attracting attention as a clean medium for recent global environmental issues, and demand for energy sources is expected to increase in the future.
- thermochemical cycle As a conventional method for producing hydrogen, a method of obtaining water by electrolysis and a method using a thermochemical cycle are being studied.
- electrolysis method conventional processes are being improved and new processes are being developed with the aim of improving energy efficiency.
- new processes are being developed with the aim of improving energy efficiency.
- the power situation like in Japan it is not considered to be effective as a total balance.
- the following various methods have been proposed or implemented for the thermochemical cycle, but each has its own problems.
- This method has the disadvantage that the reaction temperature is high, carbon dioxide is emitted, which causes global warming, and the equipment becomes large-scale.
- This method is a method NEDO attempted, as shown in FIG. 2, which consists of eight processes iron one steam system, the temperature of generating Fe_ ⁇ by deoxidizing the Fe 3 0 4 is that not high There are drawbacks, and the equipment becomes complicated because of combining multiple reactions.
- Figure 3 shows the hydrogen gas production cycle called UT-3 at the University of Tokyo, which consists of the following multistage reactions.
- CaBr 2 + H 20 Ca ⁇ + 2HBr (700 to 750)
- CaO + l / 2Br 2 CaBr + l / 20 2 (500-600)
- Fe 3 0 4 + 8HBr 3 FeBr 2 + 4H 2 0 + Br 2 (200 -30 O)
- Fe 3 ⁇ 4 + 8HBr FeBr 4 + 4H 2 0 + Br 2 ( ⁇ 20 0)
- H 2 S 0 4 H 2 0 + S 0 2 + l / 20 2 (80 Ot).
- This method also has a problem in that the reaction temperature is high and the equipment becomes complicated due to the combination of multiple reactions.
- H 2 S H 2 + 1 / 2S 2 (800)
- FeCl 3 2 FeCl 2 + Cl 2
- the prior art relating to hydrogen production is also complex and large-sized apparatus because none except electrolysis combines a high addition multistage reaction anti ⁇ degree, further involves the reaction products such as C0 2 . Therefore, the present inventors have been studying a method for producing hydrogen gas which is inexpensive, highly efficient, and does not involve a reaction product such as carbon dioxide.
- zeolite is granulated, water is brought into contact with the zeolite at a temperature of 300 to 500, and water is used as a catalyst with the zeolite as a catalyst. Decomposes directly. Hydrogen gas can be generated stably by granulating zeolite.
- Zeoraito the crystalline alumino silicon salt a major chemical composition S I_ ⁇ 2, A 1 2 0 3, H 2 0, Na 2 ⁇ a K 2 0, C aO.
- the structures are diverse, and the chemical composition is also diverse due to the unstable S i ZAl ratio of the framework, the unstable ratio of exchangeable cations, and the unstable number of water molecules in the unit cell. Therefore, at present, there are more than 40 kinds of natural zeolites and more than 150 kinds of synthetic zeolites.
- an alkali metal halide or Z and an alkaline earth metal halide are added when granulating the zeolite.
- Examples of the halogen element constituting the alkali metal halide or z and the alkaline earth metal halide include C 1 (chlorine), Br (bromine), and F (fluorine), and C 1 is most effective. Met. The reason why C1 is most effective is presumed to be that it easily forms a chloroacop complex with water molecules.
- examples of the alkali metal include Na (sodium), Li (lithium), and K (potassium), and examples of the alkaline earth metal include Mg.
- I ⁇ i was the most effective. The reason why Li is most effective is that it has the smallest ionic radius and easily exchanges with metals such as Na, Mg, and K contained in natural zeolite, so it increases the charge density of zeolite and dissociates water. It is presumed that the pressure equilibrium constant is increased and the decomposition of water is promoted.
- the addition ratio of the alkali metal halide or the alkali metal halide to the zeolite is preferably 1 to 20 g per 100 g of zeolite.
- FIG. 1 is a diagram showing an example of an apparatus for implementing the method for producing hydrogen gas according to the present invention.
- FIG. 2 is a diagram showing a conventional thermochemical cycle for continuously producing hydrogen.
- Figure 3 shows a conventional thermochemical cycle for continuously producing hydrogen.
- FIG. 1 is a diagram showing an example of an apparatus for performing the method for producing hydrogen gas according to the present invention.
- An N 2 gas is supplied to a steam generator 1 via a flow meter 2 as a carrier gas.
- the steam generator 1 is connected to a pipe 3 for drawing out the steam generated together with the carrier gas.
- a separator 4 In the middle of the pipe 3, a separator 4, a preheater 5, and a mass flow controller 6 are provided.
- the tip is connected to the bottom of a column-shaped vertical reaction vessel 7.
- the reaction vessel 7 is filled with the granulated zeolite 8, a light source 9 is arranged around the reaction vessel 7, and a pipe 10 is connected to an upper end of the reaction vessel 7.
- a bypass 11 for sampling, a pressure gauge 12 and an N 2 trap 13 are provided, and a suction pump 14 is connected to the N 2 trap 13.
- the Zeoraito using the following natural Zeoraito of Itaya the composition shown in Table 1, Examples of the metal halide was prepared NaBr, NaF, the Lick KC1 and M GCL 2.
- zeolite having the above composition 200 g is pulverized, granulated (average particle size: l to 3 mm) using an aqueous solution (5%) of each of the above metal halides, and then dried at 200.
- the addition amount of the metal halide to 100 g of natural zeolite was 5 g.
- the granulated zeolite was charged into a 200 m1 reaction vessel, the pressure in the reaction vessel was reduced by a vacuum pump, and the temperature was raised to 500, and the steam from the steam generator was removed from the reaction vessel. About 20 O ml was introduced into the flask and reacted for 2 hours.
- reaction temperature is preferably from 300 to 500.
