Abstract

The chemical analysis of a porous carbon material (PCM) from coal of the Maikube coal basin (Kazakhstan) was carried out in this work. The PCM was obtained by carbonization and activation in argon and water vapor atmospheres. The physicochemical characteristics and surface morphology of the test sample were studied. The electrophysical characteristics of the PCM were determined by measuring the electric capacity of the samples in a temperature range of 293–483 K. The temperature dependences of the specific heat were obtained by dynamic calorimetry. Equations of the temperature dependence of the heat capacity were derived, and they can be further used to determine the thermal conductivity and temperature conductivity.

迈库贝盆地煤中多孔碳材料的电物理性质和热容

摘要

在这项工作中，对迈库贝煤盆地（哈萨克斯坦）煤中的多孔碳材料（PCM）进行了化学分析。PCM通过在氩气和水蒸气气氛中碳化和活化而获得。研究了试样的理化特性和表面形态。PCM的电物理特性是通过在293–483 K的温度范围内测量样品的电容来确定的。通过动态量热法获得比热的温度依赖性。推导了热容量的温度依赖性方程，它们可以进一步用于确定热导率和温度导率。
