Abstract

''PROCESSO PARA PRODUZIR ACROLEìNA E/OU ACIDO ACRILICO A PARTIR DO PROPANO'' Um processo para produzir acroleína e/ou ácido acrílico a partir do propano, por meio do qual, o propano passa pela oxidesidrogenação homogênea parcial e/ou heterogênea catalisada em uma primeira etapa de reação com oxigênio molecular para formar o propano. A mistura gasosa do produto formada na primeira etapa de reação é usada para produzir acroleína e/ou ácido acrílico por meio da oxidação catalítica do propano de fase gasosa. O processo é caracterizado em que o oxigênio molecular que é requerido na primeira área de reação e que é diferente do gás oxigênio reciclado, é adicionado à mistura gasosa de reação inicial da primeira área de reação como ar modificado contendo nitrogênio com a condição de que o teor de nitrogênio do ar modificado seja menor do que, e o teor de oxigênio do ar modificado seja maior do que os teores de ar correspondentes. A invenção é ainda caracterizada pelo fato de que pelo menos uma parte do nitrogênio molecular contida no fluxo de gás residual é separada do fluxo de gás residual antes do fluxo de gás residual ser retornado para a primeira área de reação.
