Reduction of Polycyclic Aromatic Hydrocarbons in Coal Tar Pitch by Chemical Conversion 煤沥青化学改性减少致癌多环芳烃含量的研究
Study on polycyclic aromatic hydrocarbons in low-temperature coal tar from Lurgi coal gasification 鲁奇煤气化工艺低温煤焦油中多环芳烃的研究
We have successfully synthesized the condensed polynuclear aromatic ( COPNA) resin using coal tar pitch as monomer and divinylbenzene ( DVB) as cross-linking agent in the presence of p-toluene sulfonic acid, the pyrolyzed substance structures and properties of which are studied in this paper. 本文进行了以煤沥青为单体、二乙烯基苯(DVB)为交联剂缩合多核芳烃(COP-NA)树脂热解产物的结构与性能研究。
Capillary gas chromatography Fourier transform infrared spectrometry gas chromatography retention indices ( GC/ FTIR RI), combined with the linear relationship between retention value and boiling points for polycyclic aromatic hydrocarbons, performed the determination of the composition of heavy oil fractions in high temperature coal tar. 在原有工作基础上,采用毛细管气相色谱/傅立叶变换红外光谱-色谱保留指数(GC/FTIR-RI)联合解析技术,研究了高温煤焦油重油馏分的化学组成。
Capillary Supercritical Fluid Chromatographic Analysis of Polycyclic Aromatic Hydrocarbons in Airborne Dust From Tar Furnace 焦炉降尘中多环芳烃的毛细管超临界流体色谱分析
The main components of the tar from sludge air gasification are composed of benzene and its compounds, polycyclic aromatic hydrocarbons, olefins and nitrogen-containing compounds, etc. Among the tar components, phenol and naphthalene are of the highest concentrations, about half of the total content. 污泥空气气化焦油主要成分包括苯及其化合物、多环芳烃、烯烃、含氮化合物等,其中苯酚和萘含量最高,大约共占总含量的一半。
The phenol, belongs to aromatic compound with high toxic and recalcitrant to degradation, is the raw or middle materials during the fields of paper-making, tar and oil factory. 苯酚是造纸、炼焦、炼油等行业生产的原材料或中间体,它属于芳香族化合物,毒性强且较难降解。
