Abstract
Sposób regeneracji katalizatora Ti-MCM-41 charakteryzuje się tym, że roztwór poreakcyjny kieruje się na filtr, gdzie oddziela się katalizator Ti-MCM-41 od roztworu poreakcyjnego i przemywa się go dwukrotnie mieszaniną wody dejonizowanej i metanolu o stosunku wagowym 1:1, w ilości 500cm3 mieszaniny na 20g katalizatora, po czym suszy się go i zawraca do procesu epoksydacji alkoholu allilowego. Katalizator Ti-MCM-41 od cieczy poreakcyjnej oddziela się na filtrze w temperaturze 20-25°C, a suszy się pod ciśnieniem atmosferycznym w temperaturze 90°C przez 5h. Katalizator Ti-MCM-41 przemywa się i suszy na filtrze w kolejnych cyklach do momentu gdy konwersja alkoholu allilowego osiągnie wartość 0% mol, wówczas katalizator, który utracił aktywność po przemyciu i suszeniu poddaje się kalcynacji w piecu w temperaturze 500°C przez 5 godzin.
