Constant Volume Calorimetry02:41

Constant Volume Calorimetry

30.4K
Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...

  • 在不同的温度条件下,对不同级别的煤炭研究甲 (CH4) 吸附特性.
  • 阐明控制煤炭中甲吸附的分子层次机制.
  • 为优化煤床甲开发战略提供见解.

主要方法:

  • 使用了大法典蒙特卡洛 (GCMC) 模拟.
  • 研究了三个煤层:煤,煤和炭化石.
  • 在两个温度范围内进行了模拟:低 (293.15323.15 K) 和高 (373.151173.15 K).

主要成果:

  • 高级煤具有更发达的孔隙结构和更大的表面积,增强了CH4吸附点.
  • 高级煤的芳香度增加和表面能量均有利于CH4吸附.
