EFFECT OF ACETIC ACID PRETREATMENT TEMPERATURE ON THE FRACTAL DIMENSION OF ACACIA

摘要：

　　The acacia was pretreated by acetic acid under different temperature(140-170℃),then a three-stage refining was conducted in a high consistency disc refiner.The porous structure was investigated by low-temperature nitrogen adsorption method based on the BET theory.The fractal dimension were calculated by the Yu Boming(YBM)fractal and Frenkel Halsey Hill(FHH)fractal.The acetic acid pretreatment results in higher fractal dimension,which indicates increased irregularity of pore structure.As to the temperature effect,the higher temperature leads to lower fractal dimension.Compared to the FHH dimension,the fitting range of YBM dimension is wider with lower correlation coefficient.
