陕北中低温煤焦油的分离与GC-MS分析
Separation and GC-MS Analysis of Shanbei Low Temperature Coal Tar
摘要
Abstract
The light tar (L-tar) and heavy tar (H-tar) from Shanbei low temperature coal tar were separated by ultrasonic extraction and Soxhlet extraction to obtain petroleum ether fraction in L-tar (P-L-tarr) and petroleum ether fraction in H-tar ( P-H-tar), which could be analyzed by gas chromatography-mass spectrometry (GC-MS). The GC-MS analyses showed that P-L-tar and P-H-tar contained 295 compounds and 302 compounds respectively, which were mainly long-chain alkanes,phenols, naphthalenes, as well as a small amount of oxygen compounds and nitrogen compounds. Mass fractions of long-chain alkanes and phenols in P-L-tar are 42.43% and 18. 28% , and their mass fractions in P-H-tar are 21.53% and 36. 80% , respectively. The mass fraction of m-cresol in P-H-tar reaches 6.72%.关键词
