Abstract

resumo “geração de gás amônia a partir de ureia para exigências de processo de temperatura baixa” trata-se de um processo para fornecer uma alimentação de amônia que in-clui (i) um estágio de gaseificação térmica e (ii) um estágio de hidrólise catalisada controlada. no estágio (i), ureia, água e gases aquecidos são introduzidos em uma câmara de gaseificação a montante a uma temperatura e por um tempo suficiente para gaseificar a solução a uma corrente de gás de primeiro estágio que compreen-de amônia e ácido isociânico. a corrente de gás de primeiro estágio é introduzida em um reator catalítico de hidrólise de estágio (ii) em que o ácido isociânico é hidrolisado em amônia com dióxido de carbono como um subproduto. o processo fornece amônia para uma operação de temperatura baixa conforme necessário.
