Uppfinningen kännetecknas av att en reaktor innehållande vatten tillförs joniserande bestrålning bestående av koncentrerat solljus varvid väte- och hydroxylradikaler bildas.The present invention relates to a method and an arrangement for producing hydrogen gas from water. The invention is characterized by the fact that a reactor containing water is supplied with ionizing radiation consisting of concentrated sunlight, whereby hydrogen and hydroxyl radicals are formed.
Description
Metod och anordning för att producera väte från vatten ldag framställs vanligen väte från naturgas eller via elektrolys av vatten vilket båda är energi- krävande och kostsamma metoder. Om väte kunde framställas från vatten till låg kostnad skulle en outtömlig energikälla finnas. Världsomfattande försök pågår med målet att via arti- ficiell fotosyntes spjälka vatten likt vad som sker i Fotosystem ll som är det första ledet i väx- ternas fotosyntes, en fotolys där vattenmolekyler spjälkas till vätejoner och syre. Dock har ännu inte en lämplig katalysator påträffats. Det pågår även försök att exv. via solljusbestrål- ning av solljusabsorberande kiselkarbid spjälka vatten i väte och syre. Method and device for producing hydrogen from water Today, hydrogen is usually produced from natural gas or via electrolysis of water, both of which are energy-demanding and costly methods. If hydrogen could be produced from water at low cost, an inexhaustible source of energy would exist. Worldwide trials are underway with the goal of using artificial photosynthesis to split water similar to what happens in Photosystem ll, which is the first step in plants' photosynthesis, a photolysis where water molecules are split into hydrogen ions and oxygen. However, a suitable catalyst has not yet been found. There are also ongoing attempts to e.g. via sunlight irradiation of sunlight-absorbing silicon carbide split water into hydrogen and oxygen.
Föreliggande uppfinning avser en ny metod och anordning för att producera väte från vatten, med hjälp av fotolys innefattande joniserande strålning varvid strålningen kännetecknande tillförs via koncentrerat solljus. The present invention relates to a new method and device for producing hydrogen from water, using photolysis including ionizing radiation, wherein the radiation is characteristically supplied via concentrated sunlight.
I uppfinningen enligt patentansökan SE2200039-2 skerjonisering av vatten via LED lampor varvid vatten spjälkas i väte- respektive hydroxylradikaler samtidigt som kolmonoxid tillförs vilket leder till bildande av väte och koldioxid. En nackdel är att LED lampor, liksom elektro- lys, förbrukar mycket elektricitet som det råder brist på i dagens samhälle. Och med avseende på klimatet kan även bildandet av koldioxid vara till nackdel om kolmonoxiden inte har bio- gent ursprung. In the invention, according to patent application SE2200039-2, ionization of water via LED lamps whereby water is split into hydrogen and hydroxyl radicals at the same time as carbon monoxide is added, which leads to the formation of hydrogen and carbon dioxide. One disadvantage is that LED lamps, like electrolysis, consume a lot of electricity, which is in short supply in today's society. And with respect to the climate, even the formation of carbon dioxide can be detrimental if the carbon monoxide is not of biogenic origin.
Enligt föreliggande uppfinning undviks nämnd nackdel avseende elförbrukning genom att jonisering sker via bestrålning av vatten i en behållare av kvartsglas med solljus som koncen- trerats via solfångare, exv. paraboliska rännor, runda paraboler, soltom eller konvexa linser. Kvaitsglas har fördelen av att släppa igenom joniserande UVB-strålning vilket inte skulle ske med vanligt glas. Behållaren innehåller delvis vatten och/eller vattenånga avgränsat från be- hållarens övriga utrymme via membran som släpper igenom väte men inte större molekyler. När vattnet vid bestrålningen med det koncentrerade solljuset joniseras så spjälkas i en konti- nuerlig process, på några femtosekunder, vattnen enligt reaktionen: H20 9 H- + OH-, dvs. i väte- och hydroxylradikaler, varvid lika snabbt en omfattande rekombination till vatten sker. Samtidigt formas i nämnda process, genom att väteradikaler, H- finner varandra, också väte som tillsammans med en del oparade H- passerar genom membranet och ansamlas ovan detta. Bildande av väte kan påtagligt ökas genom tillförsel av kolmonoxid med åtföljande reaktion: 2(OH- + CO) 'å H2+2CO2. Järn, exv. i pulverforrri, är ett annat altemativ som kan tillföras för att öka produktionen enligt reaktionen: 2(2FE + 3OH-) è2FE203 + 3H Uppfinningens främsta fördel är att väte kan produceras från vatten och sol, en förnyelsebar energikälla, utan användning av elektricitet. According to the present invention, the aforementioned drawback regarding electricity consumption is avoided by ionization taking place via irradiation of water in a container of quartz glass with sunlight that is concentrated via solar collectors, e.g. parabolic troughs, round parabolas, sun toms or convex lenses. Kvaitsglas has the advantage of letting through ionizing UVB radiation, which would not happen with ordinary glass. The container partially contains water and/or water vapour, separated from the rest of the container's space via a membrane that lets hydrogen through but not larger molecules. When the water is ionized during the irradiation with the concentrated sunlight, the water is split in a continuous process, in a few femtoseconds, according to the reaction: H20 9 H- + OH-, i.e. in hydrogen and hydroxyl radicals, whereby an extensive recombination to water takes place just as quickly. At the same time, hydrogen radicals, H- find each other, are also formed in the said process, which together with some unpaired H- pass through the membrane and accumulate above it. Formation of hydrogen can be significantly increased by adding carbon monoxide with the following reaction: 2(OH- + CO) 'å H2+2CO2. Iron, e.g. in powder form, is another alternative that can be added to increase production according to the reaction: 2(2FE + 3OH-) è2FE203 + 3H The main advantage of the invention is that hydrogen can be produced from water and the sun, a renewable energy source, without the use of electricity.
Figurbeskrivning Fig. l visar schematiskt Uppfinningens tillämpning vid en anordning l bestående av en i materialet kvartsglas i detta exempel rörformad behållare 2 för mottagande av koncentrerat solljus 5 reflekterat från en parabolisk ränna 3. Det ska förstås att fixturer, som likt solens strålning ej visas, för behållaren respektive paraboliska rännan är anordnade för god funktion. Behållaren innefattar ett utrymme 4 med vatten/vattenånga och en ledning 8 för vattnets till- försel och i förekommande fall även tillförsel av kolmonoxid och/eller av järn eller andra med hydroxylradikaler reaktionsbenägna ämnen vilka via ett membran 7 avskiljs från övrigt ut- rymme 6 i behållaren. I utrymmet 4 spjälkas vatten i väte samt väte- och hydroxylradikaler. Via membranet passerar väte och väteradikaler från spjälkat vatten till utrymmet 6 varifrån väte strömmar genom en ledning 10 för vidare hantering. Via en ledning 9 bortförs eventuell jämoxid och/eller koldioxid och/eller annan oxid tillsammans med vatten för vidare hantering. Fackmässiga åtgärder för exv. tillvaratagande, eller bortkylning, av värme som bildas i behål- laren 2, eller annat, beskrivs inte. Figure description Fig. l schematically shows the application of the invention in a device l consisting of a tubular container 2 in the material quartz glass in this example for receiving concentrated sunlight 5 reflected from a parabolic trough 3. It should be understood that fixtures, which, like the sun's radiation, are not shown, for the container and the parabolic trough are arranged for good function. The container includes a space 4 with water/water vapor and a line 8 for the supply of the water and, where appropriate, also the supply of carbon monoxide and/or of iron or other substances prone to reaction with hydroxyl radicals, which are separated via a membrane 7 from the rest of the space 6 in the container. In space 4, water is split into hydrogen and hydrogen and hydroxyl radicals. Via the membrane, hydrogen and hydrogen radicals from split water pass to the space 6, from where hydrogen flows through a line 10 for further handling. Via a line 9, any iron oxide and/or carbon dioxide and/or other oxide are removed together with water for further handling. Professional measures for e.g. recovery, or cooling, of heat that is formed in container 2, or otherwise, is not described.
Uppfinningen begränsas inte till utföringsexemplet ovan, utan modifikationer kan göras inom angivna patentkravs ram.The invention is not limited to the embodiment above, but modifications can be made within the scope of the specified patent claims.
