摘要: 本文采用热脱附(TDS的实验方法,以多孔性Porapak微球为样品,测定了氧气、乙醇分子在PorapakQ、N两种样品上的脱附级数n和脱附活化能Ed,并与气相色谱法测定的吸附热作了比较。得出Ed≥ΔH令人满意的结果。

Abstract: In this paper, the clcsorplion activation energies and reaction orders were studied for O2 and C2H5OHadsorbed on Porapaks by means of TDS. The results obtained were coincident with the heais of adsorption from. GCmeasurement according to the relation En- Ea=ΔH.
