用自动定硫仪考察2-甲基噻吩、苯硫醚两种含硫模型化合物在不同载体上的负载行为以及乙醇和丙酮溶剂对两种含硫模型化合物负载情况的影响,并考察了在含硫模型化合物在燃烧过程中硫的释放行为。结果表明：XK-5000自动定硫仪具有重复性好和稳定性高的优点;与二氧化硅和活性三氧化铝两种载体相比,活性炭对2-甲基噻吩与苯硫醚这两种模型化合物有更好的吸附性能;丙酮溶剂对3种载体的吸附都有促进作用,且对活性三氧化铝的促进作用最大;苯硫醚在燃烧过程释放硫的速率快于2-甲基噻吩。

In this study,automatic sulfur determination analyzer(XK-5000) was used to investigate loading behavior of sulfur-containing model compounds on the different carriers(active carbon,active alumina and silicon dioxide),the effects of solvents on the absorption ability,and sulfur release behavior of those compounds during combustion process.Results showed that XK-5000 appeared higher repeatability and stability for the sulfur determination;the absorption ability of active carbon to 2-methylthiophene and phenyl sulfide was better than that of active alumina and silicon dioxide;while acetone can promote sulfur compounds absorption on all those carriers,however the effect on active alumina is the most remarkable;the sulfur release rate of phenyl sulfide faster than 2-methylthiophene during combustion process.
