Abstract(s)

Hierarchical silicoaluminophosphate SAPO-40 was synthetized using an organosilane acting as additional porogen agent. The structural, textural and acid properties of the new material were evaluated using XRD, 29Si and 27Al MAS NMR, SEM, N2 adsorption, pyridine adsorption followed by IR spectroscopy and thermal analyses. The evaluation of the catalytic performance in the dehydration of glycerol has evidenced a high activity and a very low deactivation rate. When compared with the conventional SAPO-40, this catalyst shows higher acrolein selectivity and a significantly longer catalytic lifetime.
