| 摘 要： | 以煤矿的废弃物煤矸石为原料,研究了368 K～400 K温度范围内,煤矸石在水热体系中自转变合成了纯度和结晶度均较高的矸石基吸附剂的过程,并对其吸附性能作了初步探讨.用氮吸附静态容量法,测得该矸石基吸附剂的氮吸附等温线、比表面和孔分布曲线.通过矸石基吸附剂对苯酚的吸附实验,给出矸石基吸附剂对它的吸附等温线. 并指出合理的吸附温度、大的比表面和适当的膜化工艺对提高矸石基吸附剂的吸附量都是有效的.

| Abstract: | The study that porous glass beads were synthesized using the gangue was used as raw in this experiment to study the process that the zeolite-based adsorbent with high crystallinity and purity was synthesized by self-transformation of gangue in vapor phase of ethylamine and water at a range of 368 K-400 K and the preliminary study on its adsorption feature was made.The adsorption properties of the zeolite-based adsorbent were characterized by adsorption isotherm,specific surface area and pore distribution wi... |
