Abstract

PROCESSO PARA PREPARAÇçO DE CIANETO DE HIDROGÊNIO (HCN). A presente Invenção relates a um processo para preparação de cianeto de hidrogénio pelo processo Andrussow por reação de gás contendo metano, amônia e gás contendo oxigênio sobre um catalisador em temperatura elevada, em que a proporção em volume de oxigênio em relação ao volume total de nitrogênio e oxigênio (02/(02 + N2)) fica na faixa de 0,2 a 1,0 e a reação é realizada com uma mistura de gás reagente não sujeita a ignição.
