Abstract: To purify synthetic gases, the technique of pressure swing adsorption process is used. Three kinds of zeolite, type 13X, 5A, NaY and active carbon were used to determine the adsorption equilibrium of CO2 and CO by static(weighing)and flowing method respectively. The amounts of CO2 adsorbed with 13X zeolite and active carbon are larger than others. The representation of adsorption isotherms of CO2 can be done with Langmuir or Freundlich equation. The amounts of CO adsorbed with all the four kinds of adsorbent are small. The adsorption and desorption breakthrough curves of CO2 with type 13X zeolite and active carbon in COa-N2 binary system were investigated.

摘要： 本文分别用静态称重法测定了CO_2和CO在5A,13X,NaY分子筛与活性炭上的吸附等温线,用流动法测定了CO_2-N_2体系中CO_2在13X分子筛与活性炭上25℃时的吸附等温线以及透过曲线（break-through curve）。吸附等温线分别用Langmuir方程和Freundlich方程回归。
