摘要: 以内蒙古某地的煤矸石为原料,采用低温(450 ℃)碱融活化法对样品进行活化,并添加导向剂水热合成4A沸石。实验在30~60 ℃的低温晶化条件下进行,晶化时间为24 h。利用XRD、SEM、FT-IR和BET等测试手段对不同温度下生成的4A沸石加以表征,间接地评价生成沸石的质量。结果表明,在晶化温度为30 ℃时,样品中便有少量的4A沸石生成;当温度达到50 ℃时,即可得到形态较佳、粒径约为2 μm且结晶度较好的4A沸石。

Abstract: This experiment takes the coal gangue of Inner Mongolia as the raw material,uses alkali fusion method at low tem- perature(450 ℃) to activate the test sample,and synthesizes 4A zeolite by hydrothermal method with adding crystallization directing agent.The experiments were carried out at crystallizing temperatures at 30~60 ℃ and crystallizing time of 24 h.4A zeolites synthesized at different temperatures were characterized by XRD,SEM,FT-IR,and BET etc.to evaluate the quality of as-prepared zeolites indirectly.Results showed that there was a small number of 4A zeolite generated in samples at crystallizing temperature of 30 ℃.But when the temperature reached 50 ℃,4A zeolite with better morphology,higher crystallinity,and 2 μm particle size could be obtained.

Key words: coal gangue, low temperature, alkali fusion, hydrothermal synthesis, 4A zeolite
