摘要：1. Method and arrangement for execution of the method in the form of aphotoreactor for photochemical dissociation of water and reduction of nitrogen from theair on the basis of the alkali-oxide photosystem dissolved in molten alkali hydroxide asproton transfer system, characterized by that the micro-paracrystalline areas in the meltare used near their melting point as smallest operable elements of the photoreactorwith a gas area belonging to the total of all elements, and that in the micro-paracrystallites two additional intermediate photosystems preferably on the basis ofalkali hydride and alkali peroxide for absorption of the light energy are formed, whichreact in the excited state with molecular nitrogen diffusing-in from the gas area inreductive and oxidative manner, such that the resulting compounds can be transferred ina thermal way into nitrogen-oxygen compounds as final products, whereby the defects ofthe lattice in the microparacrystalline areas can be used in multiple way, and that is firstas lattice location for photoelectrons to be located and as centre for the reaction with

protons, in order to form, thus, the first intermediate photosystem in the lattice in acontrolled way, while the second photosystem is formed by dimerisation of the radicalsresulting from the primary photoprocess, and second, to fix molecular nitrogen from thegas area for the direct reduction with the first excited intermediate photosystem or forthe direct oxidation with the second excited intermediate photosystem, and third, to fixoverheated water vapour from the gas area for the reaction with the excess alkali oxidebeing formed during the process to form alkali hydroxide.
