对炼焦过程中产生排放的多环芳烃特性进行分析研究,利用超声波萃取和高效液相色谱技术,测定了单煤、配煤炼焦各阶段产生的16种PAHs的含量.研究结果表明,升温初期的1～4 h内PAHs的产生量最多,其中具有四环结构的居多,具有"三致"作用的苯并[a]芘超标排放,是PAHs的重要污染源之一.

The characteristic of polycyclic aromatic hydrocarbons produced during coking has been studied.The contents of 16 kinds of PAHs are determined by use of ultrasonic abstraction and liquid chromatography technique of high performance.The study results indicate that PAHs are released most in 1-3 hours of early coking stage.Tetranuclear PAHs are generated and released mostly in the course.BaP is generated exceeding standard which is carcinogenic,teratogenesis and mutated,and it is one of the important sources of PAHs pollution.
