Abstract: The catalyst texture is one of the important features for characterizing catalyst properties.In this paper,the Image Texture Analysis Technique is introduced to analyze the SEM images of PAcatalysts in order to obtain the catalyst texture information.It is found that the texture entropy feature(F9) is in close relation with the activity of catalysts.An appropriate surface texture model corresponding to the high activity catalysts for the oxidation of naphthalene to PA is deduced as: The model is consistent with the results of activity evaluation andphysical chemistry analysis such as XRD,TPD-MS,ESR.

Key words: Catalyst texture, Surface texture model, Catalysts for naphthaiene oxidation to phthalic anhydride
