用ＡＳＡＰ－２０００型物理吸附仪，研究了制备高碳醇Ｃｕ－Ｆｅ系催化剂的比表面积、孔结构、孔容积和孔径分布等．结果表明，随着焙烧温度的提高，比表面积下降；在相同的焙烧温度下，组成和沉淀过程的ｐＨ值也影响其表面积大小．催化剂的活性与反应可利用的表面积相关．根据吸附－脱附等温线，确定了催化剂的孔结构及孔径分布的变化规律．数据表明，孔径分布和孔容积对催化剂的活性至关重要，平均孔径（４Ｖ／Ａ，根据ＢＥＴ）可作为衡量Ｃｕ－Ｆｅ系催化剂活性高低的一个参数．焙烧温度的选择是使催化剂具有适宜的孔径分布和较大的孔容积，因而具有较高活性的重要条件
The specific surface area, pore structure, pore volume and pore size distribution of Cu-Fe catalyst with high carbon alcohol were studied by ASAP-2000 physical adsorption instrument. The results showed that the specific surface area decreased with the increase of calcination temperature. The composition and the pH value of precipitation also affected the surface area at the same calcination temperature. The activity of the catalyst is related to the available surface area for the reaction. According to the adsorption-desorption isotherms, the pore structure and pore size distribution of the catalyst were determined. The data show that pore size distribution and pore volume are important for the activity of the catalyst. The average pore size (4V / A, according to BET) can be used as a parameter to measure the activity of the Cu-Fe catalyst. The calcination temperature is chosen so that the catalyst has a suitable pore size distribution and a larger pore volume, and therefore has the important condition of higher activity
