Abstract
Al2O3 B2O3 catalysts were synthesized by co-precipitation and impregnation methods applying two calcination temperatures
and boria loadings. Catalysts were analyzed by IR spectroscopy of pyridine and CO2 adsorption and were evaluated in methanol
dehydration. Results showed that boron addition to alumina causes a decrease of the number of basic and Lewis acid sites on
alumina surface. It could also be observed an enhancement in acid strength of Lewis sites for impregnated samples. The results
of methanol dehydration show that strong Bro¨nsted sites are not formed on borate alumina.
