Abstract

PROCEDIMIENTO DE PREPARACION DE ANHIDRIDO MALEICO. SE BASA EN LA OXIDACION DEL BENCENO CON UN GAS QUE CONTIENE OXIGENO, Y EN PRESENCIA DE UN CATALIZADOR QUE COMPRENDE UNA PARTE ACTIVA DISTRIBUIDA SOBRE UN SOPORTE. EL SOPORTE ESTA CONSTITUIDO POR PARTICULAS CON FORMA DE MEDIOS ANILLOS, DE DIAMETRO EXTERIOR, CINCO MILIMETROS; INTERIOR, DOS MILIMETROS, Y LONGITUD, CINCO MILIMETROS. EL SOPORTE SE IMPREGNA CON UNA SOLUCION DE OXIDOS DE MOLIBDENO, OXIDO DE VANADIO, ELEMENTOS PROMOTORES, ESTABILIZANTES Y OTROS. SE DEJA SECAR VARIAS HORAS A TEMPERATURA INFERIOR A 100 C, Y SE CALCINA A 400 C EN AMBIENTE CERRADO DURANTE TRES A SIETE HORAS.
