皖西霞石正长岩合成沸石分子筛及提钾的实验研究

SYNTHESIZING ZEOLITE MOLECULAR SIEVE AND PREPARING POTASSIUM CARBONATE FROM NEPHELINE SYENITE OF WESTERN ANHUI PROVINCE

合成沸石因具有优异的吸附及离子交换性能而备受关注。本实验以皖西地区霞石正长岩为主要原料 ,成功地合成了 13 X型沸石分子筛 ,母液经蒸发、分离 ,制得了白炭黑及碳酸钾 ,表明霞石正长岩具有巨大的潜在综合利用价值。合成沸石、白炭黑和碳酸钾的成分、结构及性能分析表明 ,3种产品均达到了国家或化工行业标准。基于此 。

Synthetic zeolite is very important because of its good adsorption and ion exchange properties.13X zeolite molecular sieve is synthexized using potash feldspar rich powder prepared from a nepheline syenite sample from western Anhui Province.Potassium carbonate and white carbon black are prepared by evaporation and separation procedure for the mother solution of synthesizing zeolite.The properties of the synthetic zeolite,potassium carbonate and white carbon black all satisfy China national chemical industry standards.
