A new type of active carbon, CF-1, was used as the stationary phase in gas chromatography. The adsorption of n-alkanes C2-C5, 1-alkenes C2-C4, acetylene, alcohols, ethyl ethers, CO2, H2S and SO2 was studied. The measurements were carried out with the original adsorbent and after its reduction with hydrogen at a temperature of 1 000°C. The original and pretreated active carbon were evaluated on the basis of the determined retention data and calculated value of the differential heats of adsorption.
