Abstract

LA INVENCION SE REFIERE A UN METODO DE OBTENCION DE UN CATALIZADOR QUE PRESENTA LA SIGUIENTE FORMULA EMPIRICA DONDE A = SN, TI, O MEZCLAS DE LOS MISMOS D = AL MENOS UN ELEMENTO SELECCIONADO A PARTIR DE LI, MG, NA, CA, SR, BA, CO, FE, CR, GA, NI, ZN, GE, NB, MO, W, CU, TI, TA, SE, BI, CE, IN, AS, B, AL Y MN, Y DONDE M = 0,5 A 10 A = 0 A 10 D = 0 A 10 X = NUMERO DE ATOMOS DE OXIGENO NECESARIOS PARA SATISFACER LOS REQUERIMIENTOS DE VALENCIA DE LOS OTROS ELEMENTOS. DICHO METODO CONSISTE EN HACER REACCIONAR UN ION DE MONOPEROXIDOVANADIO, VO(O 2 + , EN SOLUCION ACUOSA, CON UNA PRIMERA PORCION DE UN COMPUESTO DE SB QUE CONTIENE SB CON UNA VALENCIA 3 + , REDUCIENDO ASI LA VALENCIA MEDIA DEL V A MENOS DE 5 + , Y OXIDANDO EL SB HASTA UNA VALENCIA DE 5 + ; ELIMINAR EL AGUA DE LA SOLUCION PARA FORMAR UN PRECURSOR DEL SECO DEL CATALIZADOR; Y CALCINAR DICHO PRECURSOR A UNA TEMPERATURA ENTRE 650 Y 950ºC PARA FORMAR EL CATALIZADOR. LA MEJORA CONSISTE EN AÑADIR AL MENOS UNA SEGUNDA PORCION DE UN COMPUESTODE SB, TRAS LA ADICION DE LA PRIMERA PORCION DE COMPUESTO DE SB QUE HA REACCIONADO PARCIALMENTE CON EL ION DE MONOPEROXIDOVANADIO.
