Modified porous graphite as well as preparation method and application thereof
The invention discloses modified porous graphite as well as a preparation method and application thereof, and belongs to the technical field of porous graphite preparation. The preparation method of the modified porous graphite comprises the following steps that raw material coke is smashed, graded and mixed and then mixed with a binding agent and a pore forming agent for spheroidizing granulation, the mixing spheroidizing granulation time is 0.5-2 h, and the granulation size is 0.5-0.8 mm; the mass ratio of the raw material coke to the binder to the pore-forming agent is (65-70): (20-30): (5-20); and then pressing, roasting and graphitizing at high temperature to obtain the product. The preparation process of the modified porous graphite is simple, the obtained modified porous graphite is uniform in component, ordered in pore diameter arrangement, high in transmittance, few in impurities and high in porosity, and the needed raw materials are wide in source, cheap and easy to obtain.
本发明公开了一种改性多孔石墨及其制备方法和应用，属于多孔石墨制备技术领域。所述改性多孔石墨的制备方法包括如下步骤：原料焦经粉碎分级混合后与粘结剂、造孔剂混合球化造粒，混合球化造粒时间为0.5～2h，造粒大小为0.5～0.8mm；原料焦、粘结剂和造孔剂的质量比为65～70:20～30:5～20；然后经压制、焙烧、高温石墨化，即得。改性多孔石墨制备过程简单，且得到的改性多孔石墨成分均匀、孔径有序排布、透过率高、杂质少、气孔率高，而且所需原料来源广且便宜易得。
