SiO₂에 담지된 Cu-Ca 촉매 상에서의 Cyclohexanol 탈수소 반응
金海源,李淳錫 慶一大學校 1999 論文集 Vol.16 No.5
Copper and calcium catalyst ispersed on silica support, it was properly prepared by precipitation method, and was found to be better than commercial catalyst with respect to the conversion, and selectivity for the dehydrogenation of cyclothexanol to cyclohexanone. The lowest loading was desiable to achieve the highest conversion and selectivity, but the formation of side products suppressed when the copper loading silica was kept above 60 %. By the results of SEM and DT/TGA the Cu-Ca/SiO₂catalyst show the high thermal stagility and low pressure drop. These propertis are good for industrial use and long life time.
