M. Popova et al., METHANOL CONVERSION TO LIGHT ALKENES OVER SAPO-34 MOLECULAR-SIEVES SYNTHESIZED USING VARIOUS SOURCES OF SILICON AND ALUMINUM, Applied catalysis. A, General, 169(2), 1998, pp. 227-235
Depending on the various sources of Si and Al used for the synthesis,
SAPO-34 materials with different degrees of crystallinity and density
of acid sites, as shown by TPD of ammonia and TPD-TGA of 1-propanamine
have been prepared. The effect of the different acidities on the acti
vity, selectivity and lifetime of the catalysts in the reaction of met
hanol conversion to Light alkenes has been studied. (C) 1998 Elsevier
