利用ECP技术测定正构烷烃在5A分子筛上的吸附等温线

Measurement of Adsorption Isotherms of n-alkane on 5A Molecular Sieve with ECP Technology

本文采用 ＥＣＰ（Elution By Characteristic Point） 技术， 对正构烷烃（Ｃ５－Ｃ１０）在５Ａ分子筛上的吸附等温线，实验温度为１６８℃－２８１℃，压力为０－１２０mmHg。实验无论从方法和测定数据上都填补了国内的空白，为快速测定吸附等温线提供了确实可行的方法。

The adsorption isotherm of n-alkane (C5-C10) on 5A molecular sieve is obtained by using ECP (elution by characteristic point) technique under the temperature of 168℃－281℃ and the pressure of 0-120mmHg. Both the testing technique data are original in China. It provides a fast and reliable way to have adsorption isotherm.
