In contrast with the catalyst prepared with the conventional help (pure SiO2), the modification of SBA-15 with Cs improved the stability of the catalyst up to 170 h of response, and the acrolein yield was the same as before regeneration at 773 Ok in air. When the glycerol concentration within the feed was elevated to 20 wt %, the acrolein yield slightly decreased, and the catalyst was stable during a shorter TOS regarding the reaction with 10 wt % of glycerol within the feedstock.

Zeolites modified by ion-change have additionally been tested in the glycerol dehydration.
