Sp. Elangovan et al., SAPO-5 AND SAPO-11 - SYNTHESIS, CHARACTERIZATION AND CAMPHENE ISOMERIZATION ACTIVITY, Reaction kinetics and catalysis letters, 55(1), 1995, pp. 153-159
SAPO-5 and SAPO-11 were synthesized using aluminium isopropoxide and t
etraethyl orthosilicate as source materials for aluminium and silicon,
respectively, adopting a modified procedure. The as-synthesized mater
ials were characterized by XRD and chemical analysis. Acidity was foun
d by temperature-programmed desorption using TGA. Unit cell parameters
were calculated for both as-synthesized and calcined materials. The c
atalytic activity of SAPO-5 and SAPO-11 in camphene isomerization was
studied and selective formation of tricyclene was achieved.
