APLIKASI ZEOLIT NaX YANG DISINTESIS DARI ABU TERBANG PLTU OMBILIN UNTUK PENYERAPAN GAS CO2
Abstract: Synthesis of zeolite
from Ombilin coal fly ash through alkaline hydrothermal at 600C by using sea water method
has been carried
out. Fourier Transform
Infra Red (FT-IR) and
Scanning Electron Microscopy
(SEM) analysis that NaX zeolite obtained, but for X - Ray Diffraction (XRD)
analysis was produced sodalite
(Na8(Al6Si6O24)Cl2), a host
molecule for the
simple NaX zeolite.
NaX zeolite was application
for CO2 gases
adsorption compared with
nature zeolite, which
has molecular sieve 1,0 nm, and natural zeolite impregnating with methyl diethanol amine (MDEA) and piperazin
mixed. In continue adsorption
system test, result
NaX zeolite has
greatest adsorption power about
2,05 mmol CO2/g
adsorbent. Compared to
nature zeolite (mordenite and klinoptilolite type),
molecular sieve 1,0
nm and nature
zeolite were impregnated
with MDEA-piperazin has adsorption
power 0,1; 0,17
dan 0,48 mmol
CO2/g adsorbent. The differences of adsorption was affected
by base behavior, Si/Al ratio, surface
area, pore volume, and pore diameter.
