摘要:对两种煤焦油柴油馏分和石油基催化裂化柴油、焦化柴油、直馏柴油中的含氮化合物进行了鉴定分析。采用硅胶柱分离富集5种柴油中的非碱性含氮化合物,酸萃取法萃取碱性含氮化合物,利用GC/MS分离定性。结果表明:煤焦油柴油馏分中非碱性含氮化合物主要是咔唑和吲哚类化合物,碱性含氮化合物以喹啉、吡啶和苯胺类为主;催化裂化柴油以咔唑和吲哚类非碱性含氮化合物为主;焦化柴油以吡啶和喹啉类碱性含氮化合物为主;直馏柴油中主要是咔唑类非碱性含氮化合物,还有少量的喹啉和苯胺类碱性含氮化合物。煤焦油柴油馏分和焦化柴油以碱性含氮化合物为主,催化裂化柴油和直馏柴油以非碱性含氮化合物为主,煤焦油柴油馏分中的碱性含氮化合物种类及含量远高于石油馏分。
In this paper, nitrogen compounds in two kinds of coal tar diesel fraction and three kinds of diesel(FCC diesel, coking diesel and straight-run diesel)were separated and identified. The non-basic nitrogen compounds was separated by silicagel column and the basic nitrogen compounds was extracted from diesel by HCL, then the separated nitrogen compounds were identified by using GC/MS. The results show that in two coal tar diesel fractions, non-basic nitrogen compounds including carbazole and indole as well as basic nitrogen compounds including quinoline, pyridine and aniline are the main nitro- gen compounds. The basic nitrogen compounds including pyridine and quinoline are given priority in co- king diesel. Straight-run diesel mainly contains non-basic nitrogen compounds including carbazole and a small amount of basic nitrogen compounds including quinoline and aniline. The basic nitrogen corn pounds are mainly in coal tar diesel fraction and coking diesel, and the non-basic nitrogen compounds are mainly in FCC diesel and straight-run diesel. The kinds and amount of basic nitrogen compounds in coal tar diesel is much more than that in petroleum diesel.
