Abstract

PROCESSO PARA PRODUÇçO DE HIDROGÊNIO GASOSO A PARTIR DA FRAGMENTAÇçO MOLECULAR DA ÁGUA. A invenção ora descrita propõe um processo eficiente de produção de hidrogênio molecular gasoso (H2) em escala industrial, a partir da utilização de um oxidróxido de ferro, preferencialmente o õ-FeOOH, como fotocatalisador heterogéneo sólido. O aspecto inovador da tecnologia consiste na produção de hidrogênio molecular gasoso a partir de um processo químico em que a reação fotocatalítica é ativada por radiação de luz visível. O rendimento final é comparável àqueles em que se utilizam outros semicondutores sob luz uItravioleta, conforme processos descritos na literatura técnico-científica. O hidrogênio obtido pelo processo proposto pode ser utilizado para qualquer aplicação tecnológica, industrial, agrícola ou de controle/monitoramento ambiental, como, por exemplo, substância precursora para produzir energia (i) por queima direta, em (ii) células/pilhas a combustível ou (iii) via reações de produção de combustível liquido (como pela reação Fisher-Tropsch) ou (iv) em qualquer aplicação em que o hidrogênio (H2) seja empregado, como em processos de hidrogenação ou que envolvam redução química.PROCESS FOR PRODUCTION OF GAS HYDROGEN FROM WATER MOLECULAR FRAGMENT. The invention described herein proposes an efficient process of producing industrial-scale molecular hydrogen gas (H2) from the use of an iron oxide, preferably δ-FeOOH, as a solid heterogeneous photocatalyst. The innovative aspect of the technology is the production of gaseous molecular hydrogen from a chemical process in which the photocatalytic reaction is activated by visible light radiation. The final yield is comparable to those using other semiconductors under ultraviolet light, according to processes described in the technical-scientific literature. The hydrogen obtained by the proposed process can be used for any technological, industrial, agricultural or environmental control / monitoring application, such as a precursor substance to produce energy (i) by direct burning in (ii) fuel cells / cells. or (iii) via liquid fuel production reactions (as by the Fisher-Tropsch reaction) or (iv) in any application where hydrogen (H2) is employed, as in hydrogenation processes or involving chemical reduction.
