文章摘要
Abstract
In this paper, ordered mesoporous alumina (OMA) support with the high surface area (328 m2 g?1) and the large pore volume 0.74 (cm3·g?1) was synthesized by homogeneous precipitation method. And the influence of EDTA on the physical and chemical properties of the modified catalysts was also studied. The characteristic results showed that the addition of EDTA could adjust the metal-support interaction and improved the acidity of the corresponding catalyst. Combined with the catalytic performance results, the EDTA-modified NiMoE(1.0)/OMA catalyst displays the highest DBT hydrodesulfurization conversion (97.7%).
