对利用合成沸石从废气中捕集汞进行了初步研究。对合成沸石（Na-X和Na-P1）、天然沸石（斜沸石）和含溴活性炭（AC/Br）从气态流中吸收汞进行了测试。对材料进行了汞吸附试验，并对其热稳定性进行了评价。未经处理的合成沸石对汞的吸收可以忽略不计，但经银浸渍后，对汞的吸附明显提高。浸渍银的合成沸石Na-X在突破前对汞的吸附量明显高于浸渍溴的活性炭，这表明粉煤灰沸石作为一种新型的烟气汞吸附剂的潜力。
An initial study has been made of the use of synthetic zeolites for mercury capture from exhaust gases. Synthetic zeolites (Na-X and Na-P1), and for comparison a natural zeolite (clinoptilolite) and activated carbon with bromine (AC/Br) were tested for mercury uptake from a gaseous stream. The materials were subjected to mercury adsorption tests and their thermal stability was evaluated. The untreated synthetic zeolites had negligible mercury uptake, but after impregnation with silver, the adsorption of mercury was markedly improved. The synthetic zeolite Na-X impregnated with silver adsorbed significantly more mercury before breakthrough than the activated carbon impregnated with bromine, indicating the potential of zeolite derived from coal fly ash as a new sorbent for capture of mercury from flue gases.
