Abstract

PROCEDIMIENTO PARA LA REELABORACION DE CATALIZADOR DE FLUORACION. COMPRENDE: A) MEZCLAR A LOS CATALIZADORES VIEJOS CON OXIDO DE MAGNESIO O HIDROXIDO DE MAGNESIO EN PRESENCIA DE GRAN CANTIDAD DE AGUA; B) CONCENTRAR Y EVAPORAR LA MEZCLA; C) AMASAR LA MEZCLA EN UN AMASADOR DUPLEX, PARA FORMAR UNA PASTA; D) SECAR LA PASTA A UNA TEMPERATURA ENTRE 40 Y 150JC, Y BAJO VACIO; Y E) TRATAR A LA PASTA SECA CON UNA CORRIENTE DE FLUORURO DE HIDROGENO (FH) EN GAS INERTE COMO NITROGENO Y AIRE, A UNA TEMPERATURA ENTRE 100J Y 400JC, DURANTE 0,5 A 10 HORAS. LAS CANTIDADES DE REACTIVOS SON 0,01 A 1 KG MGO O 0,00145-1,45 KG DE MG(OH)2 POR 1 KG DE CATALIZADOR VIEJO Y 0,2 A 2 MOLES DE FLUORURO DE HIDROGENO POR MOL DE OXIDO O HIDROXIDO DE MAGNESIO. SE UTILIZAN COMO REACTORES DE LECHO FIJO, LECHO FLUIDO O DE CAPA TURBULENTA PARA REACCIONES DE FLUORACION Y/O DISMINUCION CON HALOGENOS/ALCANOS.
