摘要：The structure of coke from five spent residue hydrotreating catalysts was investigated based on ruthenium ion catalyzed oxidation reaction. The distribution of n-alkyl chains and bridges attached to aromatic carbon of coke on catalysts was quantified. Results showed the concentrations of n-alkyl chains and bridges in coke were declined with the increase of carbon number. The substituential group is methyl mainly, and it had no C5 alkyl chains in coke. Various isomeric benzenepolycarboxylic acids from oxidated products were identified. Then the condensation mode of some aromatic structure was discussed. The precursor of coke affected the coke structure. Catalysts made coke dehydrogenate to form graphite type aromatic condensate. About 60% of coke was graphite type.
