摘要
环境保护关于硫含量的严格规定 ,要求对燃料中含有的稳定硫成分进行深度脱硫 ,开发新型高效催化剂是降低难脱硫含量的一个有效方法 .同常规硫化钼催化剂相比 ,氮化钼作为一种新型的氢化反应催化剂 ,表现了良好的脱硫活性和 C—S键断裂的选择性 .对该催化剂的制备、表面性质、结构、活性相等进行了概括 。
Strict environmental regulation on the content of sulfur in fuel can be expected to be the driving force for deeper HDS to desulfurize the more stable sulfur containing molecules, and developing new type catalysts possessing high activities is an effectively method to eliminate undesirable sulfur. Compare to the commercial molybdenum sulfide catalysts,as a new type hydrotreating catalyst, γ Mo 2N has high activity of desulfurization and selectivity of C S bond′s cleavage. The review summarizes its synthesis method, surface and structure properties,the phase of activity and so on. Furthermore it prospects the feasibility in hydrodesulfurization of coal derived liquid.\;
