沸石改性及其吸附性能研究

Study on modification and adsorption of zeolite

对沸石进行降低硅铝比改性 ,改性沸石对H2 O、H2 S、NH3 的饱和吸附量分别为 16 .8%、18.2mg/ g、71.1mg/ g,而只进行过焙烧的沸石为 9.3%、11.7mg/ g、38.4mg/ g ,表明沸石经降低硅铝比改性后 ,对H2 O、H2 S、NH3 的吸附量大大提高。

Adsorption capacity for H 2O?H 2S and NH 3 of zeolite modified by decreasing ratio of silicon and aluminum was 16.8%,18.2mg/g and 71.1mg/g, respectively. That of zeolite modified by heating was 9.3 %,11.7mg/g and 38.4mg/g respectively. This showed that zeolite modified by decreasing ratio of silicon and aluminum had good adsorption capacity.
