Abstract

"PROCESSO PARA A OXIDAçãO PARCIAL DE PROPENO A ACROLEìNA EM FASE GASOSA". A invenção refere-se a um método para a oxidação em fase gasosa parcial heterogeneamente catalisada de propeno para formar acroleína, pelo qual a mistura inicial do gás da reação é oxidada em um leito de catalisador de leito fixo, que consiste de pelo menos duas zonas de leito de catalisador de leito fixo e está disposta em duas zonas de temperatura sucessivas A e B, com uma carga de propeno < 160 NI propeno/1 de leito de catalisador de leito fixo. A temperatura mais alta da mistura do gás da reação dentro da zona de reação A é mais alta do que a temperatura da mistura do gás da reação dentro da zona de reação B.
