CHARACTERIZATION K3PO4/NaZSM-5 USING XRD AND FTIRudAS A CATALYST TO PRODUCE BIODIESEL

摘要

Synthesis of NaZSM-5 and impregnation of K3PO4 catalyst with concentration 5, 10, andud15 wt.% on the resulting NaZSM-5 as a catalyst to produce biodiesel have been done inudthis study. This study is an experimental study, the research stages include the synthesisudand characterization NaZSM-5 and K3PO4/NaZSM-5. Characterization by X-RayudDiffraction (XRD) was conducted to determine the X-ray diffraction patterns and theudpercentage crystallinity of the samples. X-ray diffraction pattern of the resulting sampleudshowed the emergence of diffraction peaks with high intensity at 2θ = 7.8; 8.8; 23.0; 23.2,udand 24.3° are specifically indexed to the structure of the MFI topology. The percentageudcrystallinity of the sample becomes smaller with increasing number of K3PO4udimpregnated on NaZSM-5 synthesis. Characterization of the samples by FourierudTransform Infra Red (FTIR) aims to determine the type of functional groups present in audcompound. FTIR spectra of samples NZ, NZK5, NZK10 and NZK15 have absorptionudbands in the region 1220 and 547 cm-1 which shows the absorption characteristics ofudvibration T - O - T on NaZSM-5 type zeolite which distinguish the other and sensitive toudchanges in structure. The results of characterization using XRD and FTIR showed thatudthe structure of NaZSM-5 remained unchange after impregnated with K3PO4.
