HH-5Å 填充柱测定气体的详细资料
填充柱测定气体
吸附是多相反应和多相催化的重要基元步骤,在该过程中可能存在着多种作用,如范德华力、氢键力、静电力、疏水交互作用、化学键等。按照作用方式的不同,吸附可以分为化学吸附和物理吸附。由于作用力不同,各种吸附所释放的热也不同,因此可以用吸附热来表征固体吸附剂,特别是。
滕州市浩瀚色谱仪器技术服务有限公司研发出
,填充柱测定气体,结合气相色谱分析方法的特征,应用反相气相色谱法,以N2、CO为探针分子,在不同温度下测定了新制备的分子筛-1、-2、-3、-4的保留时间,以保留时间的对数对温度倒数进行回归分析。结果得到线性关系良好的曲线,由此曲线计算得到这些分子筛对CO和N2的吸附热范围分别为26.60~30.12kJ,25.0~28.01kJ。本研究的结果表明,反相气相色谱法能测定出结构微小改变时的吸附热差别。

HH- column
Adsorption is an im
portant elementary step of heterogeneous reaction and heterogeneous catalysis. In this process, there may be many functions, such as van der Waals force, hydrogen bo
nding force, electrostatic force, hydro
phobic interaction, chemical bonding, etc. According to different modes of action, adsorption can be divided into chemical adsorption and physical adsorption. Due to the different forces, the heat released by various adsorption is also different, so the adsorption heat can be used to characterize the solid adsorbent, especially.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. developed the HH- chromatographic column, combined with the characteristics of the gas chromatography analysis method, using reversed-phase gas chromatography, using N2 and CO as probe molecules, and measuring the new preparation at different temperatures The molecular sieve -1, -2, -3, -4 retention time, the logarithm of the retention time to the regression analysis of the inverse temperature. As a result, a curve with a good linear relatio
nship was obtained. From this curve, the adsorption heat range of these molecular sieves for CO and N2 was 26.60~30.12kJ, 25.0~28.01kJ, respectively. The results of this study indicate that reversed-phase gas chromatography can determine the difference in the heat of adsorption when the structure changes slightly.
