以中国辽河（LDAO）和委内瑞拉奥里诺科河（VDAO）为原料，对无沥青质减压渣油进行了催化加氢处理。采用电喷雾电离（ESI）傅立叶变换-离子回旋共振质谱（FT-ICR MS）对LDAO和VDAO加氢前后进行了分析，以确定加氢处理后含氮化合物的结构组成变化。结果表明，加氢处理前后两种DAO的碱性氮含量相对稳定。然而，加氢处理后的LDAO和VDAO的中性氮含量明显降低。尽管加氢处理前LDAO的中性氮含量高于VDAO，但LDAO的中性氮转化率高于VDAO。两种DAOs脱氮效果的显著差异是由于中性氮化合物的结构变化所致。通过绘制双键当量（DBE）值与…
Asphaltenes-free vacuum resid derived deasphalted oils (DAOs) from Chinese Liaohe (LDAO) and Venezuela Orinoco (VDAO) were subjected to catalytic hydrotreating. Electrospray ionization (ESI) Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS) analyses were performed on LDAO and VDAO before and after hydrotreating to determine the structural composition transformation of nitrogen-containing compounds as a result of hydrotreating. The results showed that the basic nitrogen contents of the two DAO before and after hydrotreating were relatively constant. However, the neutral nitrogen contents of hydrotreated LDAO and VDAO were dramatically reduced. The LDAO had a higher neutral nitrogen conversion than VDAO, even though LDAO had a higher neutral nitrogen content than VDAO prior to hydrotreating. The significant difference in nitrogen removal for the DAOs was due to the structural variation of the neutral nitrogen compounds. By plotting the double bond equivalent (DBE) value as a function o...
