不同制备条件对生物焦汞吸附特性及吸附动力学的影响
Effects of different preparation conditions on kinetics and adsorption of mercury by biomass char
摘要
Abstract
In order to obtain the characteristic of biomass char on mercury adsorption,the biomass char prepared with various conditions was studied.The influence of preparation condition of biomass char on mercury adsorption was obtained.These preparation parameters include biomass species,particle size,temperature and oxygen concentration.The adsorption kinetic characteristics of biomass char was investigated,which can provide theoretical foundation for further research on the mechanism of biomass char on mercury adsorption.The results show that there are differences in mercury adsorption by biomass char with various preparation conditions.The pore structure influenced greatly in physical adsorption.The more cumulative pore volume of biomass char and thus the more mercury adsorbed.The specific pore volume plays a more significant role than specific surface area in the mercury adsorption process.The adsorption process was effected by both chemical adsorption and physical absorption,and the former is an important rate-limiting process.关键词
