摘要

研究了4种不同蒙古煤的活化特性。煤在550℃的温度下炭化，得到的样品用预热蒸汽活化。用氮气吸附法测定了活性炭的孔径、孔体积和比表面积。阿杜温楚伦煤(ACAC)、Shivee Ovoo煤(SCAC)、Baganuur煤(BCAC)和乌兰Ovoo煤(UCAC)的BET表面积分别为283、205、251和460 m2/g。Langmuir表面积ACAC为283 m2/g, SCAC为230 m2/g, UCAC为537 m2/g, BCAC为254 m2/g。

Investigation on physical activation of some Mongolian coals

Activation characteristics of four different Mongolian coals were investigated. The coals were carbonized at temperatures of 550 °C and the obtained samples were activated by preheated steam. The pore size, pore volume and surface areas of all activated carbons (AC) have been determined by adsorption of nitrogen (N2) gas. The BET surface areas of Aduunchuluun (ACAC), Shivee Ovoo (SCAC), Baganuur (BCAC) coal and Ulaan Ovoo coals (UCAC) are 283, 205, 251 and 460 m2/g respectively. Langmuir surface area is 283 m2/g of ACAC, 230 m2/g of SCAC, 537 m2/g in UCAC and 254 m2/g in BCAC.
