从3类吸附剂入手介绍炭基类吸附剂脱汞吸附的研究现状。活性炭脱汞是目前的研究热点;飞灰的脱汞性能不及活性炭。但具有显著的价格优势;活性炭纤维是第三代活性炭产品,与粒状活性炭相比有其特有的物性优势。
The progress of research in the removal of mercury by carbon-based sorbents based on three adsorbents is reviewed. Using the activated carbon to remove mercury has drawn lots of attention recently; while the adsorptive capacity of fly ash is much smaller than activated carbon, it has great advantage of price; activated carbon fibers, the third generation of activated carbon, has the peculiar physical properties comparing to the granular activated carbon.
