摘要
Abstract
Objective The aim is to study the characteristics of low-temperature adsorption and high-temperature desorption of a renewable mercury removal agent,in order to provide references for the selection of process parameters.Method The adsorption experiments of renewable mercury removal agents at different temperatures and the desorption experiments under different programmed heating conditions were carried out.Result The renewable mercury removal agent had adsorption capabilities for mercury vapor at 20-80℃,but the higher the temperature,the weaker its adsorption capacity.The results of the constant rate heating desorption experiment showed that the desorption curve of the mercury removal agent exhibited a bimodal characteristic,with the main peak area dominating.The higher the constant temperature,the higher the mercury desorption rate of the renewable mercury removal agent.The constant temperature time and adsorption time had little effect on the mercury desorption rate of the renewable mercury removal agent.Conclusion The adsorption temperature of the renewable natural gas mercury removal should be controlled below 60℃.Considering the temperature resistance of steel and regeneration energy consumption,the constant temperature during regeneration should be controlled at about 300℃.关键词
