Abstract
Un proceso para producir partículas esféricas de catalizador que contienen una zeolita como elemento activo, de acuerdo al cual un sol que contienecristales de zeolita y por lo menos un compuesto formador de gel se pulveriza desde abajo directamenteen una zona de reaccion que contiene un gas de reacciontal que el sol que rompe en globulos de sol individuales inmediatamente antes o al entrar a la zona de reaccion, los globulos del sol fluyen a través de lazona de reaccion sobre una trayectoriac urva, al hacerlo son pre-consolidados, y los globulos de sol son recolectados sobre un medio de recoleccion. Por mediodel proceso es posible obtener partículas esféricas de catalizador que contienen zeolita como elemento activo que presentan (a)un d iámetro en el rango de 0,01a 5 mm, preferiblemente 0,02 a 3,5 mm, (b) un área de superficie específica en el rango de 1 a 900 m2/g, preferiblemente de 100 a 800 m2/g (medida de acuerdoal registro y evaluacion de curvas de sorcion de nitrogeno),(c) u na densidad aparente en el rango de 0,1 a 1g/ml, (d) un volumen de poros en el rango de 0,25a 2,5 ml/g (medido de acuerdo a porosimetría de mercurio o al registro y evaluacion de curvas de sorcion de nitrogeno), (e) una distribucion dediámetro depor o que tiene un máximo (distribucion de poro monomodal) en el rango de 15 a 2000 Amstrong, preferiblemente de 15 a 400 Amstrong (medida de acuerdo aporosimetría de mercurio o al registro y evaluacion de curvas de sorcion de nitrogeno).Las partículas de catalizador son utiles en el proceso para laepoxidacion de compuestos olefínicos con la ayuda de un peroxido, preferiblemente peroxido de hidrogeno, a un epoxido, preferiblemente 1,2-epoxi-3-cloropropanoo 1-2-epoxipropano.
