Abstract

Un método mejorado para la oxidacion selectiva de propileno a acroleína en fase vapor en un sistema reactor de solidos recirculantes por medio de oxidomultimetálico de molibdato de bismuto que involucra concentraciones específicas de los reactivos (de manera preferida, entre 5 moles % y 30 moles % depropileno, entre 0 y 20 moles % de oxígeno y el resto un gas inerte ), un determinado tamano de partículas (entre 1 y 300 micrometros), una ciertatemperatura (250 a 450s C) y determinados períodos de resistencia del gas (entre 1 y 15 segundos) y de los solidos (entre 2 y 60 segundos). Este procesotiene como resultado una selectividad mejorada y la conversion de propileno.An improved method for the selective oxidation of propylene to acrolein in the vapor phase in a recirculating solids reactor system by means of bismuth molybdate molybdate, involving specific concentrations of the reagents (preferably, between 5 mol% and 30 mol% of propylene , between 0 and 20 moles% oxygen and the rest an inert gas), a certain particle size (between 1 and 300 micrometers), a certain temperature (250 to 450s C) and certain periods of gas resistance (between 1 and 15 seconds) and solids (between 2 and 60 seconds). This process results in improved selectivity and propylene conversion.
