摘要

Distribution and thermal behaviors of oil-soluble Mo dithiocarbamate (Mo DTC) and Mo dithiophosphatc (Mo DTP) as the MoS_2 catalyst precursors were studied using FT-Far IR in petroleum vacuum residue (VR). FT-Far IR was proved to detect the complexes and their derived MoS_2 in VR without interference of the organic matrix. Their decomposition into MoS_2 was identified by detection of change in the ligand bonds. There was found no preferencial distribution of the complexes in maltene or asphaltene, ruling out any interaction of the complex with asphaltene. Mo-DTC was found to be decomposed at 350℃ to form definite MoS_2 in VR whereas Mo-DTP was decomposed about 250℃ without formation of definite MoS_2, suggesting their different activities for VR up-grading.
