摘要：
Because the acidic compounds of the feedstock of T refinery (FTAC) have special high corrosivity, the composition and class distribution of the acidic compounds were analyzed by electrospray ionization Fourier transform ion cyclotron resonance mass spectroscopy, and compared with the acidic compounds of the lubrication distillation fraction from D refinery and commercial naphthenic acids. This study indicates that the feature of FTAC is exceptionally high proportion of acyclic carboxylic acids, aromatic acids, and alkylphenol-like compounds, which are some of the reasons for the high corrosivity of the feedstock of T refinery.
