摘要

The activity tests of used HDS catalysts,which were prepared durig 30 days of aging under various HDS reaction conditions,were performed and their characteriation was performed to understand the initial deactivation of the HDS catalysts.The pore volume measurements revealed that th sealed space of pore increased withaging,resultingin HDS catayst deactivation.Laser Raman and ~(13)C-NMR analysis showed that aromaticity of coke was the highest at the center of the catalyst pellet and was influenced more by reaction temperature than by reactiopressure.Comparison of HDS activity of the used catalysts with real feed to that with a model compound observed between HDS activity and coke content,suggesting that coke deactivation was predominant at the start of run,regardless of HDS reaction conditions involved.
