Abstract

corpo sinterizado moldado, e método para a produção de corpo sinterizado moldado. a presente invenção refere-se a um corpo sinterizado moldado contendo um composto de tipo maienita, um material sinterizado de aglutinante inorgânico, e um metal de transição, em que um teor do material sinterizado de aglutinante inorgânico é de 3 a 30 partes por massa com relação a 100 partes por massa do corpo sinterizado moldado, e em uma distribuição de tamanho de poros do corpo sinterizado moldado obtida por medição de distribuição de tamanho de poros por um método de adsorção de nitrogênio, o corpo sinterizado moldado tem pelo menos um pico de poros em cada uma de uma faixa de diâmetro de poros de 2,5 a 20 nm e uma faixa de diâmetro de poros de 20 a 350 nm. a presente invenção também se refere a um método para a produção do corpo sinterizado moldado, incluindo mistura de um precursor de um composto de tipo maienita e um material bruto de um material sinterizado de aglutinante inorgânico; moldagem da mistura; queima do corpo moldado; e suporte de um metal de transição no produto queimado, em que a etapa de preparação da mistura é uma etapa de combinação do material bruto de modo a satisfazer o conteúdo aglutinante inorgânico acima mencionado, provendo assim um corpo sinterizado moldado tendo alta atividade catalítica e alta resistência de trituramento.
