摘要:
采用傅里叶红外光谱(FT-IR)、热重(TGA)和固体核磁(13C NMR)等方法,研究渣油加氢脱金属过程中积炭在催化剂上的沉积类型、沉积过程及其结构演变.结果表明:催化剂表面上的积炭可明显地分辩为两种不同类型的炭,即致密炭和疏松炭.在整个渣油加氢脱金属过程中,随着反应的进行,积炭结构逐步由富脂肪型炭向芳香型炭转变,积炭的前后沉积模式存在明显的“先快后慢”特征.
Abstract:
The structural evolution, deposition type and pattern of coke on residue hydrodemetallization catalyst were studied by FT-IR, TGA and 13C NMR. The results showed that two types of cokes on the surface of catalysts were observed definitely: refractory coke and soft coke. The comparative study of fresh and used catalysts showed that the aliphatic structures of coke are gradually translated into aromatic structures with increasing catalyst age. The coke deposition, during entire hydroprocessing period, is characterized by “growing fast at the beginning and then getting slow”.
