An overview of physical adsorption methods for the characterization of finely divided and porous materials and their application to fluid cracking catalysts

摘要

Other than in degree of automation,basic gas adsorption measurement techniques have changed very little in the last half century,whereas our understanding of the adsorption process and the interpretation of adsorption data for the characterization of finely divided or porous materials has advanced significantly in recent years.This contribution will attempt to review,somewhat critically,some of the older,more commonly used data reduction methods and present some of the newer insights gained from the application of simulation techniques such as density functional theory(DFT),Monte Carlo methods and Molecular Dynamics.
