中文摘要：

Languuir方程是由单分子层吸附模型推导出来的，在理论上，煤层吸附CO不符合单分子层吸附模型。温度较低时，由于煤层吸附CO得到的吸附等温线都属于第1类吸附等温线。所以吸附CO的量可以用Langmuir方程计算；温度较高时，吸附CO的量与煤层压力呈线性关系。煤层中CO吸附模型的确定可以提高自然发火预测预报的准确性，为进一步研究一氧化碳在煤层中的赋存机理提供了依据，减少不必要的自然发火预防措施的实施，提高经济效益。确保煤矿的安全生产。

英文摘要：

Langmuir equation is based on the absorption model of monomolecular layer. Theoretically ,CO absorption in coal doesn＇ t conform to absoption model of monomolecular layer. At low temperature, both absorption models of monomolecular layer and CO absorption in coal are described by Type I absorption isotherm. So Langmuir equation can be commonly used to study CO absorption in coal. At high temperature, the relationship between the CO absorption in coal and the pressure is linear. The assurance of CO absorption model can increase the accuracy of estimation the spontaneous combustion and provide basis can decrease unnecessary prevention measure for studying the mechanism of CO absorption in coal ; at same time, it and increase the economic perform for working safely in mining.
