Abstract

La invencion se refiere a un procedimiento para la fabricacion de compuestos de peroxígeno revestidos especialmente percarbonato de sodio, medianterecubrimiento en lecho fluidizado. Mediante el empleo de un reactor de lecho fluidizado con un fondo deafluencia radial, cuyas aberturas de paso dejan salirel gas de fluidizacion en la zona de abertura en un ángulo de menos de 35s, medido respecto de la horizontal, en la forma de corrientes parciales dirigidas yen la cual están dispuestas las toberasde rociado, cuyo impulso se manifiesta en la misma direccion que el impulso del gas de flluidizacion, se logra obtenerproductos con mayor estabilidad de oxígeno activo. Se prefiere un reactor redondo cuyo fondo de afluencia posee láminas con forma de álabes de turbinaentrecruzados y toberas orientadas en la direccion de rotacion del lecho fluidizado en el fondo de afluencia.
