the catalyst carrier. The powder of alumina was prepared from recrystallization of alum and
the effect of yeast cell addition as pore forming agent was studied to form porous γ-alumina.
The weight percentage of yeast cell added to prepare of porous gamma alumina are (5%,
10%, 15% and 20%) and the gel casting method was used for preparation of porous gamma
alumina. The result showed that the Gel-casting method by using yeast cell as pore forming …
