Abstract

SE PROPONE UN PROCESO PARA DESTRUIR ACIDO FORMICO Y/O FORMALDEHIDO EN UNA CORRIENTE RESIDUAL ACIDA, ACUOSA, ORGANICA PONIENDO EN CONTACTO LA CORRIENTE CON UN CATALIZADOR DE METAL PRECIOSO SOPORTADO Y PASANDO AIRE U OXIGENO MOLECULAR GASEOSO A TRAVES DE LA SOLUCION PARA FAVORECER LA OXIDACION QUIMICA. LA INVENCION ES UNA ALTERNATIVA SEGURA, PRACTICA Y RENTABLE AL TRATAMIENTO CON SISTEMAS BIOLOGICOS DE ESTOS COMPUESTOS UTILIZANDO MICROORGANISMOS. EL PROCESO DE LA INVENCION PUEDE SER PUESTO EN PRACTICA TANTO EN MODO CONTINUO COMO POR LOTES Y, SEGUN LA INVENCION, EL ACIDO FORMICO PRESENTE EN UNA CORRIENTE EN UN NIVEL DE 3800 PPM Y EL FORMALDEHIDO PRESENTE EN UNA CANTIDAD DE 5800 PPM PUEDEN SER REDUCIDOS RESPECTIVAMENTE A NIVELES DE 200 PPM O MENOS.
