Partial Oxidation of Ethane to Acetic Acid Catalyzed by MoVNbPd Catalyst Supported on Titania

Yousef S. Al-Zeghayer
Abstract—The partial oxidation of ethane to ethylene and acetic acid was examined over catalyst based on unsupported and supported Mo-V-Nb oxides with and without Pd. The supports are different types of titania. Catalyst characterization was carried out uxing XRD, SEM, and BET surface area. The reaction was carried out in differential reactor at temperature range 200-2750C and total pressure 200 psi. Unsupported Mo16V6.37Nb2.05Ox showed activity and selectivities resemble those reported previously. Titania with different grades was examined as a support for Mo16V6.37Nb2.05Ox .The selectivities of products kept without significant change when titania P25 was used as a support for Mo16V6.37Nb2.05Ox whereas the other grades cristal AF4.60, AF7.70, and AF12.5 showed either low catalytic activities and/or combustion reactions. Supported Mo16V6.37Nb2.05Ox over TiO2(P25) led to increase the catalyst surface area from 30 to 38.58 m2g-1. The introduction of trace amounts of Pd led to the depletion of ethylene and to a significant increase in acetic acid synthesis rate.

Index Terms—Acetic acid, ethane, ethylene, MoVNbPd catalyst, partial oxidation.
