摘要：利用盐酸-乙醇溶液对焦化蜡油(CGO)中的碱性氮化合物进行了萃取分离,采用电喷雾-傅里叶变换离子回旋共振质谱仪(ESI FT-ICR MS)对CGO及其盐酸抽提物中的碱性氮化合物进行了表征,并在小型提升管催化裂化实验装置上,考察了碱性氮化合物的催化裂化反应特性。结果表明:CGO中的碱性氮化合物以N1类化合物为主,主要是带烷基或环烷基侧链的喹啉类和苯并喹啉类衍生物;在催化裂化条件下,萃取出的碱性氮化合物仍具有一定的催化裂化性能,但转化率较低,主要发生烷基侧链、环烷基侧链以及联苯桥键的断裂反应,较高含量的碱性氮化合物和多环芳烃是导致其转化率低、产物分布差的关键因素。
The basic nitrogen compounds were extracted by hydrochloric acid and alcohol from CGO.Then the types and structures of basic nitrogen species in CGO and its hydrochloric extract were characterized by Electrospray Ionization（ESI） Fourier Transform Ion Cyclotron Resonance Mass Spectrometry（FT-ICR MS）,and the catalytic cracking performance of the basic nitrogen compounds was studied.The data indicate that N1 type basic nitrogen compounds are dominant in CGO and these species are mainly derivatives of quinoline and benzoquinoline with alkyl and cycloalkyl chains.Under the conditions of FCC,the basic nitrogen compounds extracted from CGO still have certain catalytic cracking ability;however,the conversion is relatively low.The bond-breakages of alkyl side-chains,cycloalkyl side-chains and biphenyl bridge are the main reaction.High content of basic nitrogen compounds and polycyclic aromatic hydrocarbons are the key factors that lead to lower conversion and poorer products distribution.
