滕州市浩瀚色谱仪器技术服务有限公司,重新推导并简化了采用反相气相色谱法来测定吸附热力学参数的计算公式,并且在不同温度下,对N2和CO在4种分子筛上色谱保留时间进行了测定,对测定结果以推导公式为函数作线性回归,并且计算了吸附热力学参数ΔadH,ΔadS和ΔadG。结果表明,保留时间与1/T相关性很好,CO的吸附热随着分子筛Ca2+交换度的增加而增加,随着H+交换度的增加而减少,N2的吸附热则随着Ca2+交换度的增加变化不明显,随着H+交换度的增加而减少;CO和N2的吸附热在-25.36—-29.39 kJ/mol,4种分子筛对N2和CO的吸附熵在-80.01—-73.96J/(mol.K)和-72.13—-60.48 J/。

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. re-derived and simplified the calculation formula for the determination of adsorption thermodynamic parameters by reversed-phase gas chromatography, and carried out the chromatographic retention time of N2 and CO on four molecular sieves at different temperatures. For the measurement, the measurement results were linearly regressed by using the derivation formula as a function, and the adsorption thermodynamic parameters ΔadH, ΔadS and ΔadG were calculated. The results show that the retention time is well correlated with 1/T. The adsorption heat of CO increases with the increase of Ca2+ exchange degree of molecular sieve, and decreases with the increase of H+ exchange degree. The adsorption heat of N2 increases with Ca2+ exchange degree. The increase is not obvious, and decreases with the increase of H+ exchange degree; the heat of adsorption of CO and N2 is -25.36--29.39 kJ/mol, and the adsorption entropy of N2 and CO by four kinds of molecular sieves is -80.01--73.96J/( Mol.K) and -72.13--60.48 J/.
