| 摘 要： | 研究了干燥方式对载体硅胶的比表面积、平均孔径和孔容的影响。结果表明:采用厢式干燥、喷雾干燥和超临界流体干燥,硅胶的比表面积分别为413.2,296.7,420.2m2/g;其孔容分别为1.227,1.525,3.014mL/g;而其平均孔径分别为15.16,18.94,29.37nm。显然不同干燥方式对硅胶的比表面积、孔容和平均孔径均产生了较大的影响。

| Abstract: | The influence of drying process on the specific surface area,average aperture and pore volume of silica gel as carrier were studied.The results showed that by adopting box drying,spray drying and supercritical fluid drying process,the specific surface area of silica gel was 413.2,296.7, 420.2 m~2/g,the pore volume was 1.227,1.525,3.014 mL/g and the average aperture was 15.16,18.94,29.37 nm respectively. |
