摘要： 应用计算机纹理分析技术,以分形理论及萘氧化制邻苯二甲酸酐钒系催化剂为样本,通过改变K2SO4、P2O5助剂含量,研究了多相催化剂的表面形貌.结果表明,催化剂表面分数维D随助剂的含量发生变化,D在极大值时邻苯二甲酸酐的收率最高。

Abstract: The surface texture of heterogeneous catalysts was characterized by using the fractal theory method,computer image texture analysis technique,the catalyst for the oxidation of naphthalene to phthalic anhydride as the sample,and by changing the content of promoter K2SO4 and P2O5 in this paper.The experimental results show that the fractal dimension value Dchanged with the variation of the promoter contents and the yield of phthalic anhydride reached the highest value when Dvalue was maximum.
