“…Muitos autores 11,25,27 relatam o papel do cobre como agente desidrogenante, assim como espécie intermediária no crescimento das cadeias de carbono formando produtos oxigenados, via reações com etanol. A formação de acetaldeído (Reação 5) provém da reação de desidrogenação do etanol, que é factível nas temperaturas usadas nos testes catalíticos.…”

“…The approach, based on green chemistry, employs renewable resources (Ruppert et al, 2012). Copper-based catalysts have been successfully employed for the selective conversion of ethanol to ethyl acetate or acetaldehyde (Chang et al, 2003;Volanti et al, 2011). The best results for selective conversion of ethanol to ethyl acetate have been achieved with ZrO 2 -supported copper catalysts (Iwasa and Takezawa, 1991;Inui et al, 2002;Gaspar et al, 2010;Wang et al, 2010).…”

“…However, moderating the acidity could reduce coke formation and enhance the steadystate catalytic activity of HZSM-5. Another important pathway for ethanol decomposition is dehydrogenation to acetaldehyde and hydrogen, which is favored on basic [26] or metallic catalysts [27]. Chang et al reported that copper catalysts supported on rice husk ash displayed high catalytic activity and selectivity towards dehydrogenation products [27].…”

Chang et al reported that copper catalysts supported on rice husk ash displayed high catalytic activity and selectivity towards dehydrogenation products [27]. Much attention has been focused on preparing bifunctional catalysts with both acidic and basic sites in order to promote both dehydrogenation and dehydration reactions [28][29][30][31].…”
