| 摘 要： | 炭分子筛(ＣａｒｂｏｎＭｏｌｅｃｕｌａｒＳｉｅｖｅ,以下简称ＣＭＳ)是具有特别发达的微孔结构的特种活性炭,在气体分离方面有广阔的应用前景1]。目前作为变压吸附空气分离技术的首选吸附剂,在国内外被广泛用于中小规模的空气分离以制取富Ｎ2气体,制取ＣＭＳ的原料多是椰子壳、果核、植物、石油沥青及各种煤等2,3]。煤是一种具有较为发达的孔隙结构的物质,且价格低廉,来源广泛,是制取ＣＭＳ的一种较为理想的原料。鸡西地区拥有丰富的煤炭资源,开发煤炭的深加工及高附加值产品具有十分重要的意义。本文以鸡西地区的烟煤为原料,制备空…

| Abstract: | Through carbonization and Fe additive with Jixi bituminous coal as a raw material, the author research on a preparation of CMS using in production of nitrogen rich air with air separation and examine. The influence of carbonization condition and Fe additive on the air separation performance of the products, the influence of carbonization conditions such as the carbonization temperature, the heating rate and the holding time as well as the additives such as coal tar, Fe3O4 and their ratio in the raw material were studied. It is concluded that Jixi bituminous coal is a good raw material for preparation of CMS. The optimum carbonization conditions are bond dosage 35w%, Fe additive (Fe3O4) 25.3w%, heating rate 10 ℃/min, final carbonization at 900 ℃ for 60 min. |
