My final project is the effect of
hydrothermal holding time to zeolite characterization which synthesized by
geothermal sludge. Zeolite is a smart material. It is belong to microporous
material and has many advantages such as filter, adsorbent, ion exchanger and
the others. I took the gothermal sludge from geodipa energy, the owner of geothermal
plant in Dieng, Wonosobo. Geothermal sludge was dried and was distilled, and
then fused at 850 deg C. Geothermal ash mixtured with natrium aluminate and
natrium silicate to get an aluminosilicate gel. It was synthesized hydrothermally
at 100 deg C during 3,4,and 5 hours.Then,it was washed by aquabidest and was
dried in the oven at 80 deg C during 5 hours. Finelly zeolite was produced by
the process.
