PEMBUATAN KATALIS H-ZEOLIT DENGAN IMPREGNASI KI/KIO3 DAN UJI KINERJA KATALIS UNTUK PRODUKSI BIODIESEL

Abstract

H-Zeolite catalysts synthesized from natural zeolite include chemical treatment process stages, screening, washing, impregnation KI/KIO₃ and physical treatment. The objective of this research is to study characteristics of catalyst that was impregnated KI / KIO₃ with surface area analysis, X-Ray Diffraction (XRD) and performance test of catalyst for production of biodiesel. The results showed that the surface area of ​​the catalyst by 27.236 m²/ g at a concentration of 5% KI. XRD analysis of the value obtained at 2-θ peak at 23.627^o zeolite indicating that KI was impregnated on H-zeolite catalyst. The catalyst was tested for production of biodiesel using palm oil with conventional methods for 3-hour temperature of 70-80^oC. The Result for conversion Fatty Acid Methyl Ester (FAME) had maximum value on 87.91% at a concentration of catalyst impregnation variable KIO₃ 5%.
