Abstract:

Molybdenum sulfide-based (MoS2) catalysts play a critical role in hydrodesulfurization (HDS) reactions, particularly as environmental regulations become increasingly stringent. The growing demand for ultra-low sulfur fuels and the tightening of vehicle emission standards have made the development of efficient HDS catalysts a key challenge in the petroleum refining industry. MoS2 catalysts are particularly notable for their excellent catalytic activity, high resistance to poisoning, and cost-effectiveness. This paper provides an overview of the design principles, reaction mechanisms, and applications of MoS2 catalysts in HDS, along with the strategies to optimize their performance. First, we analyze the active sites of MoS2 and explore the reaction mechanisms involved in HDS. We then review the current state of MoS2 catalysts in HDS and discuss future directions, particularly the development of unsupported catalysts and their applications in HDS. Finally, we address the challenges and opportunities in identifying catalyst active sites, studying reaction mechanisms, and increasing catalyst life and cost efficiency. The paper also emphasizes the importance of in-situ characterization close to industrial reaction conditions.

Key words: hydrodesulfurization (HDS), molybdenum disulfide (MoS2), active phase, catalyst design, promoting mechanism, high pressure in-situ characterization

摘要:

硫化钼(MoS2)基催化剂在加氢脱硫(HDS)反应中具有重要的应用价值,特别是在满足日益严格的环境法规要求方面。随着环境立法的趋严,尤其是在汽车排放标准的提升和超低硫燃料需求增长的背景下,开发高效的HDS催化剂成为石油精炼行业面临的关键挑战。MoS2基催化剂因其出色的催化性能、较高的抗毒性和较低的成本,成为研究的热点。本文综述了MoS2催化剂的设计理念、反应机制及其在HDS反应中的应用,并探讨了催化剂性能优化的策略,分析了MoS2的活性位点及其在HDS反应中的反应机制。讨论了MoS2基催化剂在HDS反应中的应用现状及未来发展方向,其中重点介绍了非负载型催化剂的开发及其在HDS反应中的应用。最后,指出了催化剂活性位点的识别、反应机理的研究、催化剂寿命延长和成本降低的挑战与机遇,强调了开发接近工业反应条件下的原位表征的必要性。
