Abstract

Abstract: Catalysts CuO_x/γ-Al₂O₃-IH and CuO_x/γ-Al₂O₃-IM were prepared, characterized, and tested for styrene combustion in the absence and presence of water vapor. The effect of copper valence of the catalysts on the catalytic activity for styrene combustion was discussed using the theory of hard soft acids and bases (HSAB). The results showed that the existence of water vapor in feed stream inhibited the catalytic activity for styrene combustion due to the competition adsorption of water molecule. HSAB theory confirmed that the local soft acidity of the catalyst CuO_x/γ-Al₂O₃-IH was much stronger than that of the catalyst CuO_x/γ-Al₂O₃-IM because of the higher content of soft acid Cu⁺ on its surface, which increased the adsorption ability toward soft base of styrene and reduced the adsorption toward hard base of water vapor, and thus increased the catalytic activity for styrene combustion and weakened the negative influence of water vapor.

Key words: Catalyst combustion, Styrene, Copper based catalysts, Water inhibition, Theory of hard soft acids and bases
