Partial oxidation of methanol to formaldehyde using acid treated Iron-Molybdate catalysts |
| 초록 |
Two different stoichiometric Iron-molybdate (Mo/Fe atomic ratio=1.5 and 3.0) catalysts were prepared in presence of nitric acid. The physicochemical characterization of the prepared catalysts was carried out using BET, XRD, IR and SEM analysis. The activity of the catalysts were studied experimentally in a fixed bed reactor over a wide range of reaction conditions and it provides evidence that Fe2(MoO4)3 would be the active phase of the catalyst. The experimental results of conversion of methanol and selectivity towards formaldehyde for various residence times were studied. The results showed that as the residence time increases the yield of formaldehyde decreases. Linearity was observed in conversion of methanol with residence time. Selectivity of formaldehyde decreases with increase in residence time. This is due to the subsequent oxidation of formaldehyde to carbon monoxide, due to longer residence times. |
