| Summary: | In this study, natural source Parangtritis beach sand was extracted into mesoporous silica (MS). Synthesis of mesoporous
silica (MS) was carried out at sodium silicate: CTAB ratio of 1:0.5 (w/w). Monometallic catalyst was used to improve the
performance of the catalyst. The monometallic used was Mo metal, which was synthesized using the wet impregnation
method. Catalysts were characterized using FTIR, XRD, Surface Area Analyzer (SAA), SEM–EDX, and TEM. MS has pore
diameters and surface area of 2.62 nm and 897.3 m2/
g, respectively. Mo/MS has pore diameters, surface area, and Mo metal
concentration of 2.46 nm, 593 m2/
g, and 4.75%, respectively. Catalytic activity and selectivity were evaluated in hydrocracking
of waste palm cooking oil at 500, 550, and 600 °C, and catalyst: waste palm cooking oil ratio of 1:100, 1:200, and 1:300.
The best catalyst will be tested for reusability 3 times through the hydrocracking process. Mo/MS produces better liquid
products and hydrocarbon compounds than MS. The results of the conversion of liquid products analyzed using GCMS. The
yield of liquid products obtained in the hydrocracking of waste palm cooking oil using Mo/MS with the optimum temperature
and the weight ratio of catalyst: feed at 550 °C and 1: 300 was 66.99 wt.% with consists of hydrocarbon compound as 62.79
wt.%. The yield of liquid products obtained in the hydrocracking waste palm cooking oil using the used Mo/MS catalyst in
the last run was 80.26 wt.% with consist of hydrocarbon compound as 74.13 wt.%.
