Molybdenum Oxide based Partial Oxidation Catalyst for the Preparation of Formaldehyde from Methanol |
| 초록 |
A mixed oxide catalyst containing Mo, V and W with the composition of 64, 27 and 9% respectively was tried for the partial oxidation of the methanol to formaldehyde. The thermal activation of the catalyst shows enhanced catalytic performance. The characterization of the catalyst was done using X-ray diffraction (XRD), Infrared spectroscopy (IR), Scanning electron microscopy and Energy dispersive X-ray (EDX). Thermal activation of the nanocrystalline Mo0.64V27W0.09Ox precursor oxide in nitrogen atmospheres induces partial crystallization of a Mo5O14-type oxide only in a narrow temperature range up to 540oC. XRD showed that the thermally activated mixed oxide consists of a mixture of a majority of crystalline Mo5O14-type oxide and of small amounts of crystalline MoO3-type and MoO2-type oxides. The structural analysis suggests that the improvement of the catalytic performance of the MoVW oxide catalyst in the partial oxidation of methanol is related to the formation of the Mo5O14 type mixed oxide. |
