摘　　要：用 GC、GC-MS 法分析催化裂化轻柴油中双环芳烃(Fr.2)、多环芳烃馏份(Fr.3)的组成和含量,并借助 DI-MS 和 Fr-IR 法研究极性物馏份(Fr.4)中的主要化合物类型的归属。分析结果表明:催化裂化轻柴油中约90%为芳烃物质,其中3%为单环芳烃,31%为双芳烃,51%为多环芳烃,3%为极性的多环稠合芳烃。双环芳烃主要由 C_1—C_6烷基萘、C_1—C_4烷基联苯组成。多环芳烃馏份主要由 C_1—C_4烷基蒽菲及烷基笏组成。极性物馏份则主要由烷基咔唑、烷基二苯并呋喃系列及酚类和芳酮构成。The fractions of diaromatics(Fr.2) and polyaromatics (Fr.3) of light diesel bycatalytic cracking from previous work were characterized with GC/MS,and the com-position of its polar compound fraction(Fr.4) was determined with DI-MS andFTIR.The results thus obtained show that Fr.2 predominantly consists of C_1-C_6naphthalenes and C_1—C_4 biphenyls,Ft.3 C_1—C_4 anthracenes,phenanthrenes andfluorenes,and the polar compounds identified represent dibenzofuran and carbazoleseries.The normalization of GC peak areas points out that nearly 90% of the ana-lysed samples are aromatic compounds,of which about 3% are monoaromatics,31% diaromatics,51% polyaromatics and 3% polar compounds.
