Removal of elemental mercury from coal combustion flue gas by bentonite-chitosan and their modifier
膨润土-壳聚糖及其改性吸附剂脱除燃烧烟气中Hg0的性能研究

Adsorption experiments of vapor-phase elemental mercury were carried out by using modified bentonite-chitosan in a laboratory-scale fixed-bed reactor.VM3000 online mercury analyzer was applied to detect the inlet and outlet mercury(Hg0) concentrations.The characterizations of the sorbents were analyzed using the method of nitrogen(N2) adsorption/desorption,scanning electron microscope(SEM) and Fourier transform infra-red spectroscopy(FT-IR),etc..It was observed that the porosity and specific surface area de...
