摘要：

The present paper examines some features relevant to hydroprocessing reactions over MoS2 supported catalysts promoted by Co or Ni. After the description of the main classes of reactions, catalyst genesis and activation (i.e. sulphidation) are extensively described and discussed. The final part deals with the identification of the catalyst active sites, the role of the promoters and also presents some mechanistic considerations. (C) 1998 Elsevier Science B.V.
