Abstract
Patente de Invenção: "CATALISADOR PARA A HIDROGENAçãO DE NITROCOMPOSTOS AROMáTICOS". A invenção refere-se a catalisador de hidrogenação que compreende como suporte de carbono um negro-de-fumo com um teor de H de > 4.000 ppm e, como componente cataliticamente ativo, paládio e/ou platina ou paládio e/ou platina bi ou multimetalicamente dopados ou em forma de liga, o qual é preparado através de adição de soluções de sal de metal a uma suspensão do negro-de-fumo com teor de H de > 4.000 ppm, hidrolisando as soluções de sal de metal mediante uso de um composto básico e efetuando deposição completa do metal através de redução com um agente redutor. O catalisador de hidrogenação pode ser empregado para a hidrogenação de nitroaromáticos.
