Abstract

uma estrutura fibrosa de catalisador tendo um metal de catalisador transportado sobre uma estrutura fibrosa, em que (a) uma curva de distribuição de volume de microporos via log diferencial dos mesmos, obtida por medição usando uma técnica de intrusão de mercúrio tem um pico tendo um diâmetro máximo de microporos na faixa de 0,1 µm a 100 µm; (b) um volume de microporos via diferencial de log no pico é de 0,5 ml/g ou mais; e (c) uma quantidade de um composto de metal de catalisador e um ligante transportado por unidade de volume é de 0,05 g/ml ou mais. um método de produção para a produção de uma estrutura fibrosa de catalisador tendo: (1) mistura de um composto de metal de catalisador ou um precursor de catalisador, e um ligante inorgânico e um solvente; (2) moagem da mistura para se obter um material de revestimento do composto de metal de catalisador ou o precursor de catalisador tendo um diâmetro médio de partícula de 2 µm ou menos, e uma viscosidade de 10 mpa.s a 200 mpa.s; (3) impregnação de uma estrutura fibrosa com o material de revestimento para preencher os espaços vazios da estrutura fibrosa com o material de revestimento do composto de metal de catalisador ou o precursor de catalisador; (4) aquecimento e secagem da estrutura fibrosa, diretamente, uma vez que está, a uma temperatura não inferior ao ponto de ebulição do solvente; e (5) aquecimento e calcinação da estrutura fibrosa seca a uma temperatura não inferior à temperatura de desidratação do ligante inorgânico para se obter uma estrutura fibrosa de catalisador.
