Abstract

The CeO2 catalyst has been investigated for hydrogenation of benzoic acid to benzaldehyde and shows little deactivation in stability test. BET results indicate that no significant sinter was observed on the used catalyst. SEM images show few changes taking place in surface feature of the used catalyst. Element analysis confirms that some coke is formed which leads to catalyst deactivation. XRD analysis reveals that crystalline size of catalyst is not relevant to the catalytic behavior in the range from 14.3 nm to 18.4 nm.
