Abstract

La presente se refiere a un catalizador para preparar anhídrido ftálico por oxidacion de fase gaseosa de o-xileno y/o naftaleno, que comprende al menos tres zonas de catalizador que tienen diferente composicion, las cuales son referidas desde el lado de entrada de gas hacia el lado de salida de gas como primera, segunda y tercera zona de catalizador, teniendo las zonas de catalizador en cada caso una composicion activa que comprende TiO2, disminuyendo el contenido de composicion activa desde la primera zona de catalizador dispuesta hacia el lado de entrada de gas hacia la tercera zona de catalizador dispuesta hacia el lado de salida de gas, siempre que: a) la primera zona de catalizador tiene un contenido de composicion activa entre aproximadamente 7 y 12% en peso; b) la segunda zona de catalizador tiene un contenido de composicion activa en la zona entre 6 y 11% en peso, siendo el contenido de composicion activa de la segunda zona de catalizador menor o igual que el contenido de composicion activa de la primera zona de catalizador, y c) la tercera zona de catalizador tiene un contenido de composicion activa en la zona entre 5 y 10% en peso, siendo el contenido de composicion activa de la tercera zona de catalizador menor que o igual al contenido de composicion activa de la segunda zona de catalizador. También se describe un procedimiento preferido para preparar tal catalizador y el uso preferido de dioxido de titanio usado de acuerdo con la presente.This refers to a catalyst for preparing phthalic anhydride by gas phase oxidation of o-xylene and / or naphthalene, comprising at least three catalyst zones having different composition, which are referred from the gas inlet side to the gas outlet side as the first, second and third catalyst zone, the catalyst zones in each case having an active composition comprising TiO2, decreasing the active composition content from the first catalyst zone disposed towards the inlet side of gas towards the third catalyst zone disposed towards the gas outlet side, provided that: a) the first catalyst zone has an active composition content between about 7 and 12% by weight; b) the second catalyst zone has an active composition content in the zone between 6 and 11% by weight, the active composition content of the second catalyst zone being less than or equal to the active composition content of the first zone of catalyst, and c) the third catalyst zone has an active composition content in the area between 5 and 10% by weight, the active composition content of the third catalyst zone being less than or equal to the active composition content of the second catalyst zone A preferred method for preparing such a catalyst and the preferred use of titanium dioxide used in accordance with the present is also described.
