| Abstract |
Sulfonic-functionalized mesoporous silicas (SBA-15) were used as catalysts in the gas-phase dehydration of glycerol at moderate temperature (275 and 300 degrees C). For the tested conditions all the samples show a very high catalytic activity. At the lowest temperature and for 140 h on stream a nearly constant selectivity to acrolein of ca. 80\% could be obtained. Both the pore size and density of acid sites play an important role in the deactivation rate and selectivity: larger pore size may extend significantly the catalytic activity and high density of acid sites may reduce acrolein production. Increasing the temperature to 300 degrees C is beneficial to the acrolein production, but it also leads to an increase of the deactivation rate. (C) 2011 Elsevier B.V. All rights reserved. |
