Abstract:

The common research methods for the adsorption and diffusion of zeolite molecular sieves at home and abroad, the characteristics and applicable scope of each method, and the research status of adsorption and diffusion phenomena at home and abroad are introduced. The research results of domestic and foreign scientific research workers are systematically introduced. On this basis, the scientific problems that existed in this field are put forward. Aiming at these problems, a research program by using gas chromatography for the study of adsorption and diffusion phenomena is proposed. The principle of gas chromatography and the method of adsorption and diffusion are described in detail. The corresponding formulas are deduced, and the application of gas chromatography in the study of adsorption and diffusion is also prospected.

Key words: Molecular sieve, Adsorption, Diffusion, Gas chromatography
