Abstract

"PROCESSO PARA OXIDAçãO SELETIVA DA FASE DE VAPOR DE PROPILENO EM ACROLEìNA" A presente invenção refere-se a um método aperfeiçoado para a oxidação seletiva em fase de vapor de propileno em acroleína em um sistema reator de sólidos em recirculação, utilizando um óxido multi-metálico de molibdato de bismuto, envolvendo concentrações específicas de reagentes (preferencialmente 5% molar a 30% molar de propileno, 0 a 20% molar de oxigênio e o restante de gás inerte), tamanho de partícula (1 a 300 micrómetros), temperatura (250 a 450° C) e tempos de residência de gás (1 a 15 segundos) e sólidos (2 a 60 segundos). Tal processo conduz a seletividade e conversão de propileno aperfeiçoadas."PROCESS FOR SELECTIVE OXIDATION OF THE PROPYLENE VAPOR PHASE IN ACROLEIN" The present invention relates to an improved method for the selective oxidation in propylene vapor phase in acrolein in a recirculating solid reactor system, using a multi- metal of bismuth molybdate, involving specific concentrations of reagents (preferably 5 mol% to 30 mol% of propylene, 0 to 20 mol% of oxygen and the rest of inert gas), particle size (1 to 300 micrometers), temperature ( 250 to 450 ° C) and residence times for gas (1 to 15 seconds) and solids (2 to 60 seconds). Such a process leads to improved propylene selectivity and conversion.
