Abstract

SE PRESENTA UN PROCESO MEJORADO PARA LA OXIDACION SELECTIVA DE FASE DE VAPOR DE N-BUTANO EN ANHIDRIDO MALEICO QUE COMPRENDE EL USO DE UN REACTOR RECIRCULANTE DE SOLIDOS QUE TIENE UNA ZONA DE REACCION Y UNA ZONA DE REGENERACION DEL CATALIZADOR EN DONDE EL N-BUTANO SE CONVIERTE EN ACIDO MALEICO EN LA ZONA DE REACCION MEDIANTE EL USO DE UN CATALIZADOR DE OXIDO DE VANADIO/FOSFORO (V/P/O) EN FORMA OXIDADA Y EL CATALIZADOR DE OXIDO DE VANADIO/FOSFORO ES REGENERADO POR CONTACTO CON OXIGENO EN LA ZONA DE REGENERACION. EL REEMPLAZAMIENTO DE LAS PERDIDAS INHERENTES DEL CATALIZADOR ASOCIADAS CON EL PROCESO DE RECICLADO DEL CATALIZADOR SE REALIZA AÑADIENDO AL CATALIZADOR EN LA ZONA DE REGENERACION UN PRECURSOR DE CATALIZADOR DE OXIDO DE VANADIO/FOSFORO A UNA VELOCIDAD DE ADICION TAL QUE SE EFECTUE "IN SITU" LA CALCINACION Y LA ACTIVACION DEL PRECURSOR DEL CATALIZADOR DE OXIDO DE VANADIO/FOSFORO MIENTRAS QUE SIMULTANEAMENTE SE MANTIENE LA TEMPERATURA DE FUNCIONAMIENTO DESEADA DE LA REACCION DE CONVERSION DE N-BUTANO EN ANHIDRIDO MALEICO. EL PROCESO ES UTIL EN EL MANTENIMIENTO DE LA ALTA CAPACIDAD DE FUNCIONAMIENTO DEL REACTOR A LO LARGO DE UN PERIODO DE TIEMPO EXTENDIDO.
