摘要:
A method is developed for fabrication of an ammonia gas adsorbent using Fe-zeolite. This method uses Fe-zeolite obtained from municipal waste slag to prepare a gas adsorbent, thereby reusing molten slag as a specified waste so as to improve the value of the waste. To achieve the purpose, the method includes mixing Fe-zeolite powder with a forming adjuvant to prepare a mixture; adding a forming agent to the mixture to obtain a granular Fe-zeolite product; and drying and calcining the obtained granular Fe-zeolite product. Therefore, Fe-zeolite obtained from molten slag as a waste product can be reused as an ammonia gas adsorbent.
