Abstract
REATOR TUBULAR PARA FOTOCATÁLISE HETEROGÊNEA DE COMPOSTOS ORGÂNICOS. A presente invenção trata de um reator tubular fotocatalítico e de um processo, utilizando este reator, para tratamento de água contaminada com compostos orgânicos provenientes de fontes naturais ou de processos industriais. Para alcançar a mineralização total dos poluentes, são utilizados dois catalisadores constituídos de semicondutores. Os catalisadores são constituídos de diáxido de titânio e diáxido de zircônio (TiO~ 2~/ZrO~ 2~), os quais, na forma de um filme misto, são depositados sobre um substrato e ativados com luz artificial proveniente de uma lâmpada de luz negra. A presente invenção tem seu uso no tratamento de águas superficiais e subterrâneas contaminadas com compostos recalcitrantes aos tratamentos convencionais e no tratamento de diversos efluentes provenientes de processos industriais e/ou domésticos.TUBULAR REACTOR FOR HETEROGENIC PHOTOCATALYSIS OF ORGANIC COMPOUNDS. The present invention concerns a photocatalytic tubular reactor and a process using this reactor for treating water contaminated with organic compounds from natural sources or industrial processes. To achieve total pollutant mineralization, two semiconductor catalysts are used. The catalysts consist of titanium dioxide and zirconium dioxide (TiO ~ 2 ~ / ZrO ~ 2 ~), which, in the form of a mixed film, are deposited on a substrate and activated with artificial light from a light bulb. black The present invention has its use in the treatment of surface and groundwater contaminated with recalcitrant compounds to conventional treatments and in the treatment of various effluents from industrial and / or domestic processes.
