Abstract
CATALISADOR DE CAMADAS MéLTIPLAS PARA PRODUÇçO DE ANIDRIDO DE ÁCIDO FTÁLICO. A presente invenção refere-se a um catalisador para produção de anidrido de ácido ftálico por oxidação de fase gasosa de o-xileno e/ou naftalina, que contém pelo menos três camadas de catalisador, designadas como primeira, segunda ou terceira camada de catalisador, do lado de entrada de gás em direção ao lado de saída de gás, sendo que as camadas de catalisador apresentam, em cada caso, uma massa ativa, que contém TiO~ 2~, com um teor de Na de menos de 0,3%, e sendo que o teor de massa ativa diminui da primeira camada de catalisador, situada em direção ao lado de entrada de gás, para a terceira camada de catalisador, situada em direção ao lado de saída do gás, com a condição de que a) a primeira camada de catalisador apresenta um teor de massa ativa entre cerca de 7 e 12% em peso, b) a segunda camada de catalisador apresenta um teor de massa ativa no âmbito entre 6 e 11% em peso, sendo que o teor de massa ativa da segunda camada de catalisador é menor ou igual ao teor de massa ativa da primeira camada de catalisador, e c) a terceira camada de catalisador apresenta um teor de massa ativa no âmbito entre 5 e 10% em peso, sendo que o teor de massa ativa da terceira camada de catalisador é menor ou igual ao teor de massa ativa da segunda camada de catalisador. Além disso, é descrito um processo preferido para produção de um catalisador desse tipo, bem como o uso preferido do dióxido de titânio usado de acordo com a invenção.
