摘要：

The structure of the surface Mo compounds was studied by EXAFS for the hydrotreating catalysts prepared from bimetallic Co-Mo complexes and dried at different temperatures. The decomposition of the primary bimetallic compound and the formation of the inactive components were observed in the catalysts heated above 220 degrees C. (C) 2009 Elsevier B.V.
