Resumo(s)
SAPO-40 was used as catalyst for the gas-phase dehydration of glycerol towards acrolein. At 350
ºC the catalyst attained full conversion of glycerol with a negligible deactivation in the first 48 h, a
glycerol conversion above 50 % after 120 h on stream and a nearly constant selectivity to acrolein
above 70%. This catalyst proved to be highly resistant under the experimental conditions used and
can be regenerated without loss of activity or significant structural damage. The comparison of
SAPO-40 with SAPO-34 and SAPO-11 illustrates the importance of the porous structure and
emphasizes the good catalytic performance of this material.
