摘要
采用共沉淀法将钼酸铵和磷酸氢二铵盐的前驱体,通过程序升温还原法(TPR)制备了Mo P加氢脱硫(HDS)催化剂。以质量分数为0.8%的二苯并噻吩/十氢萘溶液为模型化合物,考察了催化剂的HDS反应性能,并用XRD对催化剂晶相进行了表征。实验证明,TPR还原法制备的Mo P催化剂具有较高的加氢脱硫活性。XRD表征结果表明,制备的Mo P催化剂与标准卡片(PDF 24-0771)具有完全吻合的特征衍射峰。
Mo P hydrodesulfurization（HDS） catalysts were prepared by coprecipitation method,the precursors containing ammonium molybdate and ammonium phosphate were directly converted to the active phosphide phase in the temperature-programmed reduction method（TPR）. The HDS performances of the prepared catalysts were studied using a model fuel containing 0. 8wt% dibenzothiophene in decalin,and the morphologies of the catalysts were characterized by XRD. Experiments show that Mo P prepared by TPR method catalytic performances catalyst performances were higher in the hydrodesulfurization（HDS）. XRD characterization results showed that the preparation of the Mo P catalyst and standard card（PDF 24-0771） had the characteristics of perfectly diffraction peak.
