Abstract

LA INVENCION PRESENTA UN MATERIAL CATALIZADOR Y UN METODO PARA LA DESCOMPOSICION DE CLOROFLUOROCARBUROS EN ACIDO FLUORHIDRICO, ACIDO CLORHIDRICO Y DIOXIDO DE CARBONO MEDIANTE LA REACCION CON AGUA. EL MATERIAL CATALIZADOR CONSISTE EN UN METAL SELECCIONADO DEL GRUPO QUE CONSISTE EN TI, ZR Y NB, O UNA ALEACION QUE CONSISTE EN DOS ELEMENTOS POR LO MENOS SELECCIONADOS DEL MISMO GRUPO. EL MATERIAL CATALIZADOR PUEDE ESTAR COMPUESTO TAMBIEN DE UNA ALEACION QUE CONSISTE EN HASTA UN 80% DE UN ELEMENTO POR LO MENOS SELECCIONADO DEL GRUPO QUE CONSISTE EN NI Y CO Y EL EQUILIBRIO SUSTANCIAL DE POR LO MENOS UN ELEMENTO SELECCIONADO DEL GRUPO QUE CONSISTE EN TI, ZR Y NB. LOS MATERIALES CATALIZADORES METALICOS DE LA INVENCION TIENEN UNA ACTIVIDAD CATALITICA MUY ALTA PARA LA DESCOMPOSICION DE FLUOROCARBUROS A TEMPERATURAS RELATIVAMENTE BAJAS Y PUEDEN RETENER SU ALTA ACTIVIDAD DURANTE EL PROCESO DE DESCOMPOSICION, INCLUSO SI SON CONVERTIDOS EN FLUORUROS.
