Abstract

PROCEDIMIENTO PARA OBTENER FORMALDEHIDO A PARTIR DE METANO. CONSISTE EN OXIDAR PARCIALMENTE METANO CON UN GAS CONTENIDO O2 MOLECULAR SOBRE UN CATALIZADOR DE MOO3 SOBRE UN SOPORTE DE SILICE CON UN BAJO CONTENIDO DE SODIO INFERIOR A 350 PPM, ENTRE 500 Y 700GC Y A PRESION ATMOSFERICA. EL SOPORTE DE SILICE SE ELIGE ENTRE SILICE PRECIPITADO LAVADO CON ACIDO Y SILICE FORMADO Y TIENEN UN AREA SUPERFICIAL DE NITROGENO BET DE 20 M ELEVADO A 3/G. SE UTILIZA COMO PROYECTO AHORRADOR DE ENERGIA.
