PENCIRIAN DAN UJI AKTIVITAS KATALITIK ZEOLIT ALAM TERAKTIVASI
ABSTRACT: Natural zeolite
reserves are spread in Indonesia, but they are not yet used optimally.
Generally, naturalzeolite have poor crystalline,variouspore size, lowcatalytic
activity, andhigh contaminant. Natural zeolite need to be activated and
modified before it can be used. The objectives of thisresearch were to activite
the natural zeolite that already got acid and thermal treatments and tocharacterizeitand
catalyticactivitywas testedin interesterificationreaction.Fouriertransformation
infrared (FTIR) spectra showed that the structure of natural zeolite activated
by acid and thermal (NZAT) treatments were damaged. While, natural zeolite
structure activated with acid (natural zeolite acid /NZA) did not show
significant different to natural zeolite (NZ). Result of Si/Al ratio analysis
showed that Si/Al ratio NZA higer than Si/Al ratio NZAT. The result of cation
analysis by atomic absorption spectroscopy shoed that the general content of
Na, K, Fe and Ca in the catalystdecreased because of acid and thermal
treatments. Surface area and pore volume increased by thetreatments. Catalytic
activity of NZA in interesterification reaction gave a white cork product andinyield35.78%.
