Аннотация

Исследован пиролиз стеблей бамбука (Bambos bambusa) в целях установления сохранения им исходной структуры в получаемом угле-сырце. Кусочки бамбука подвергались медленному пиролизу по периодической схеме в 4-литровом реакторе из нержавеющей стали, снабженном внешним электрическим нагревателем. Активация угля-сырца проводилась перегретым водяным паром при температуре 970 °C. Для полученного монолитного наноструктурного углеродного материала определены адсорбционная активность по иоду, удельная площадь поверхности, объем пор и их распределение по размеру. Анализ изотерм сорбции-десорбции для полученного материала и диаграмм распределения пор по размерам показал, что этот материал имеет микропористую структуру. Объем микропор, установленный различными методами, составляет 0,26...0,29 см³/г и практически не зависит от метода определения. Микропоры вносят основной вклад в пористую структуру угля, занимая 85 % общего объема.

The paper studies the pyrolysis of bamboo stems (Bambos bambusa) to preserve the original structure in the resulting lump charcoal. Bamboo pieces are subjected to slow pyrolysis in a 4-liter stainless steel reactor equipped with an external electric heater according to the periodic scheme. Activation of lump charcoal is carried out by superheated steam at a tempera-ture of 970 °C. The authors determine the adsorption activity for iodine, specific surface area, volume and pore size distribution for the obtained monolithic nanostructured carbon material. Analysis of sorption-desorption isotherms for the resulting material and pore size distribution diagrams indicate a microporous structure of the resulting material. The volume of micropores established by four different methods, is 0.26…0.29 cm3/g and is practically independent on the method of determination. Micropores make the main contribution to the porous structure of charcoal; their volume comprises the major part (85 %) of the total volume.

Keywords: bamboo, steam activation, active carbon, monolithic carbon, pyrolysis.
