Abstract: The effect of gel modification with organic and inorganic acids, and β-diketones on the textural and adsorption properties of nanocrystalline alumina synthesized by the modified aerogel procedure was studied. The highest specific surface areas obtained exceeded 1200 m2/g, being 4-5 times higher than those of typically used alumina materials. The activity of high surface area nanocrystalline alumina materials in dehydrochlorination of (2-chloroethyl)ethyl sulfide (2-CEES) and 1-chlorobutane compared favorably with that of other nanocrystalline metal oxides. The temperature of 1-chlorobutane decomposition could be decreased by ca. 100°C in comparison with MgO aerogel extensively studied earlier while maintaining 98% selectivity to butenes. Sulfated alumina aerogels had high surface areas ca. 600 m2/g after calcination at 600°C and showed excellent acidic properties typical for sulfated alumina combined with exceptionally high surface area.
