摘要

摘要:Mo和W化合物在各种化学反应中的催化作用已经被发现了几十年。以钼或钨为基本活性成分的负载型催化剂是炼油实践中应用最广泛的催化剂。尽管如此，活性Mo或W的形式及其在催化反应中的密切作用尚不清楚，尽管在这些材料中经常报道硫化物如MoS2和WS2的存在，但它们在催化反应中的参与是一个猜测问题。近年来，由于应用了现代技术，特别是光谱学，在这方面取得了重大进展。

Role of MoS2 and WS2 in Hydrodesulfuritation

Abstract Catalytic effects of Mo and W compounds in various chemical reactions have been known for decades. Supported catalysts containing Mo or W components as essential active ingredients are the most widely used catalysts in refinery practice. In spite of this, the forms of active Mo or W species and their intimate roles in catalytic reactions are not well understood, Although the presence of sulfides such as MoS2 and WS2 is frequently reported in these materials, their participation in catalytic reactions is a matter of speculation. In recent years, significant progress has been made in this respect as the result of applying modern techniques, particularly spectroscopy.
