| Abstract |
| An attempt to study the effect of solvents in the development of
porous alumina from engineered boehmite xerogel has been
made. Boehmite powder was dispersed at pH -3 to get a stable
boehmite sol. The excess water was evaporated and the resultant
gel was dried at 60°C to get a xerogel. The xerogel was
refluxed using methanol, ethanol and isopropanol, washed and
dried. The gel samples were characterized using TGA and FfiR.
The results show more interaction of methanol with the gel matrix.
The specific surface area and total pore volume of calcined
samples are presented. The nitrogen adsorption studies of the
samJlles calcined at two diiTerent temperatures are also presented
and discussed. |
