温度对改性矿物吸附剂脱除气态汞影响
Effect of temperature on removing mercury vapor with modified mineral adsorbent
摘要
Abstract
A laboratory-scale fixed-bed reactor system was used to screen some sorbents (natural vermicu- lite, mordenite, bentonite and chemically modified sorbents) for their capability to remove elemental mercury from flue gas. The characterization of all sorbents was analyzed by the accelerated surface area porosity. Conclu- sively, the temperature almost had no effect on adsorption capacity of natural vermiculite, mordenite and benton- ite. Natural sorbents had lower adsorption capacity. Appropriately increasing the chemically modified adsorption temperature improves the mercury removal, it suggests that their main sorption mechanism should be ehemisorp- tions. The activity comment CeO2 takes up a majority of surface area and porosity of mordenite, and it may play a key role. However, the adsorption capability of mordenite almost has no change after Cu0 was modified.关键词
