Abstract

MoVNbTe catalyst has been prepared using slurry method for the ammoxidation of propane to acrylonitrile (ACN). To study the effect of support on the catalytic activity of this catalyst, 10% (wt/wt) of MoVNbTe was loaded to silica (SiO2), alumina (Al2O3) and magnesia (MgO) via incipient wetness impregnation method. All MoVNbTe catalysts were calcined in air at 350-600 oC for a total of 10 h. The textural, morphological and microstructural characteristics of these catalysts were determined using scanning electron microscopy, X-ray Diffraction (XRD) and physical adsorption of Nitrogen gas. The catalytic activity of all catalysts was tested using a fixed-bed reactor with online GC at 420 oC. Results show that the physicochemical properties of these catalysts are greatly influenced by the support used.


Mangkin MoVNbTe telah disediakan menggunakan kaedah buburan bagi melakukan tindak balas ammoksidasi prop ana kepada akrilonitril (ACN). Bagi mengkaji kesan penyokong pada keaktifan mangkin, 10% (w/w) MoVNbTe dimasukkan ke dalam silika (SiO2), alumina (Al2O3) dan magnesia (MgO) melalui kaedah pengisitepuan pembasahan secukupnya. Semua mangkin MoVNbTe dikalsin di bawah aliran udara pada suhu 350-600 oC dengan jumlah masa 10 jam. Pencirian tekstur, morfologi dan mikrostruktur mangkin ini ditentukan menggunakan Mikroskopi Pengimbas Elektron (SEM), Difraktogram Sinar-X (XRD) dan penjerapan fizikal gas nitrogen. Keaktifan pemangkinan bagi setiap mangkin diuji menggunakan reaktor padatan tetap yang disambung dengan kromatografi gas (GC) pada suhu 420 oC. Keputusan menunjukkan ciri-ciri fiziko kimia setiap mangkin dipengaruhi oleh penggunaan penyokong.
