SYNTHESIS CHARACTERIZATION AND ACTIVITY OF Mg1-xNixF2 CATALYST ON PALM OIL METILATION REACTION

Author :
SARTIKA, GURUH ( 1410100069 )




ABSTRAK

Telah dilakukan sintesis doping katalis Mg1-xNixF2 x 0025 005 010 dan 015 mol pada penelitian ini dengan metode sol-gel. Katalis dikarakterisasi struktur kristal dengan difraksi sinar-X XRD dan ditentukan keasaman adsorpsi piridin- FTIR dengan metode adsorpsi nitrogen. Aktivitas katalis diuji pada reaksi metilasi minyak kelapa sawit antara RPO Refined Palm Oil dan metanol. Hasil XRD menunjukkan bahwa katalis Mg1-xNixF2 berstruktur yang sama dengan database MgF2 yaitu tetragonal. Katalis Mg1-xNixF2 memiliki asam Lewis dan asam Brnsted dari spektra FTIR. Konversi asam palmitat dan asam stearat oleh katalis MgF2 diperoleh masing-masing 033 dan 1373. Hasil terbaik dari uji katalitik diperoleh katalis Mg085Ni015F2 dengan konversi terhadap asam palmitat dan asam stearat masing-masing sebesar 451 dan 7621.


ABSTRACT

n this studied Mg1-xNixF2 x 0 0025 005 010 dan 015 mol catalysts were synthesized by a sol-gel technique. The catalysts were characterized by X-ray diffraction and acidity was determined by FTIR-pyridine adsorption analysis. The catalytic behavior of the samples were tested by metilation reaction between RPO Refined Palm Oil and methanol. The result of XRD pattern showed that the structure of Mg1-xNixF2 match with MgF2 tetragonal database. Mg1-xNixF2 catalysts have a Lewis and Brnsted acid from FTIR spectra. Conversion of palmitate acid and stearate acid by MgF2 catalyst are 033 and 1373 respectively. The best results of catalytic testing were obtained by Mg085Ni015F2 catalyst with conversion of palmitate acid and stearate acid are 451 and 7621 respectively
