Abstract
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.
