Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE REALIZACION DE REACCIONES ENDOTERMICAS PARA LA DESCOMPOSICION TERMICA DE SOLIDOS, PRODUCIENDOSE RESIDUOS SOLIDOS Y GASEOSOS. EN DICHO PROCEDIMIENTO, LOS SOLIDOS SON SUMINISTRADOS A UNA CAMARA DE REACCION, Y CALENTADOS MEDIANTE RADIACION, HASTA UNA TEMPERATURA ENTRE 500GC Y 1200GC, PRODUCIENDOSE LA DESCOMPOSICION TERMICA DE LOS SOLIDOS EN LOS CITADOS PRODUCTOS RESIDUALES SOLIDOS Y GASEOSOS, SIENDO SEPARADOS LOS GASES DE LOS SOLIDOS, Y HACIENDO POSIBLE LA RECUPERACION DEL CALOR DISPONIBLE EN LOS PRODUCTOS, PARA SU REUTILIZACION.
