A study for the durability of catalysts in ethanol synthesis by hydrogenation of carbon dioxide

Katsumi Higuchi; Yoko Haneda; Kenji Tabata; Yoshiko Nakahara; Makoto Takagawa

Absract The durability of catalysts in ethanol synthesis by the hydrogenation of CO 2 was investigated by means of XRD, TEM, and EDS. The K/Cu-Zn-Fe oxides catalyst was deactivated by the segregation of catalyst components to FeCO 2 , ZnO, and Cu during the reaction. The segregation was prevented by the addition of Cr component to the catalyst. Consequently, the K/Cu-Zn-Fe-Cr oxides catalyst indicates long catalytic life.
