摘要：

Alumina supported beta-Mo2N0.78 catalyst was synthesized via temperature programmed reaction in the N-2-H-2 mixture gases. Catalyst properties were also investigated by X-ray diffraction (XRD), BET surface area and temperature programmed reduction (TPR) methods. The HDS activity of the catalyst was measured under different Mo loading. The HDS results indicated that there was a suitable Mo loading of beta-Mo2N0.78/gamma-Al2O3 catalyst with high HDS activity. The TPR result suggested that sulfur replaced the surface oxygen of the passivated catalyst in the HDS reaction. (C) 2004 Elsevier B.V. All rights reserved.
