PENINGKATAN MUTU MINYAK JELANTAH MENGGUNAKAN ADSORBEN ZEOLIT DAN REAKTOR SISTEM FLUID FIXED BED
Abstract: Investigation of
increasing waste cooking oil quality have been done using H-zeolite as an
adsorbent and fluid fixed bed reactor which was operated in a various
temperatures. H-zeolite adsorbent was prepared through physical and chemical
treatments as follows : washing, acid, calcination and oxidation. The
characterization of this adsorbent covered cations contain (Pb, Cu, Zn, Na, K,
Ca and Fe) using AAS, Si/Al ratio using AAS, surface area spesific, pore volume
and pore diameter using surface area analyzer NOVA 1000 and acidity using
gravimetric method with amonia adsorption. Quality parametric of cooking oil
that was investigated covered water contain, acid and peroxide value and
density. Waste cooking oil as a sample was cooking oil which have been used for
frying kerupuk, tempe and tahu three times. Fifty milliliter waste cooking oil
was flowed throught 10 g H-zeolite adsorbent in fluid fixed bed reactor which
was operated at various temperatures (50, 70, 90, 110 oC). The oil was placed
in the bottle to be analyzed. The results of this research showed that the
adsorpstion process for increasing quality of waste cooking oil using H-zeolite
adsorbent and fluid fixed bed reactor
could reduce the water contain, acid and peroxide value and density. The
optimum temperature was 70 oC.
