Synthesis of Co-NH 2 /mesoporous silica bifunctional catalyst for conversion of used cooking oil into biofuel was carried out. Synthesis of mesoporous silica (MS) was done by the hydrothermal method using silica from Sidoarjo mud and gelatin from bovine bone as a template. Weight ratio variation of silica/gelatin was 4, 6, and 8 produced MS4, MS6, and MS8 respectively characterized by FTIR. The MS with minimum gelatin content after calcination (MS8) was identified using FTIR, TEM, and SAA. The impregnation of Co into the MS8 was done by the wet impregnation method and the Co/MS8 catalyst was analyzed using XRF and acidity test with NH 3 vapor adsorption. Functionalization of NH 2 into the MS8 and Co/MS8 was done by the grafting method and the products were characterized using FTIR. The catalytic activity test in used cooking oil hydrocracking was done by thermal (without catalyst), physical mixture of Co/MS8 and NH 2 /MS8 catalyst, and Co-NH 2 /MS8 bifunctional catalyst. The hydrocracking liquid products were investigated by GC-MS. The MS8 had a specific surface area of 666.76 m 2 g -1 , a pore diameter of 4.9 nm, and a pore volume of 0.46 cm 3 g -1 . The Co-NH 2 /MS8 bifunctional catalyst produced the highest liquid product of 97.62 wt.% in the hydrocracking of used cooking oil with selectivity for gasoline and diesel fraction of 3.02 and 46.86 wt.%.

“…Lewis acid site will be increased if the structure of the MS is embedded in a transition metal. 11,12 Impregnation of transition metals such as cobalt can increase acidity by giving Lewis acid sites to the carrier material. 13 This is because cobalt has empty d orbitals that can accept electrons.…”

“…The highest acidity value was obtained in the Ni1.5/C800MW catalyst, and this was due to its highest amounts of Ni metals than the others. The Ni metal has empty p-orbitals which can accept lone pair electrons from nitrogen atom in pyridine molecule [22]. Nickel metal provides Lewis acid sites, and the increase of Ni amount leads to the increase of acidity.…”

“…These radical ions can break C-C bond at the β position in hydrocarbon compounds to form shorter-chain radical compounds. When these radicals combine each other, new hydrocarbon compounds will be formed, and they tend in the form of gas [22,25]. In contrast to the amount of gas produced, the hydrocracking of α-cellulose pyrolysis oil using the Nix/C800MW produced more amount of liquid product.…”

Synthesis of mesoporous carbon from Merbau wood (Intsia spp.) waste by microwave method as nickel catalyst support for α-cellulose hydrocracking had been carried out. The Merbau wood sawdust was carbonized at 800 °C to produce C800 and the C800 was treated by microwave irradiation (399 W) for 5 min to produce C800MW. The Merbau wood flakes, which were only treated by microwave irradiation (399 Watts) for 30 min produced CMW. Wet impregnation technique was carried out to disperse the Ni metal (1.0, 1.5, and 2.0 wt.%) onto the best mesoporous carbon. The mesoporous carbons were analyzed by Fourier Transform Infra-Red Spectroscopy (FTIR), Surface Area Analyzer (SAA) and Scanning Electron Microscopy (SEM). The hydrocracking of pyrolyzed α-cellulose was carried out at 400 °C. The liquid product was analyzed by Gas Chromatograph-Mass Spectrometer (GC-MS). The results showed that the C800MW was the best performance carbon and it had a specific surface area, total pore volume, average pore diameter and acidity of 364.12 m2/g, 0.28 cm3/g, 3.03 nm, and 2.18 mmol/g, respectively. The Ni1.5/C800MW catalyst produced the highest conversion of liquid product (58.76 wt.%) than the Ni1/C800MW (57.51 wt.%) and Ni2/C800MW (34.18 wt.%).

Preparation of CuO/SiO2catalyst has been done via sol-gel method using copper nitrate solution and TEOS as precursors. Several instruments such as FT-IR, SEM, EDAX, XRD and particle sizer were employed to characterize the obtained material. Then, CuO/SiO2 catalyst was successfullyusedin the synthesis of three curcumin derivatives, 4,4'-((1E,1'E)-(1H-pyrazole-3,5-diyl)bis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 1), 4,4'-((1E,1'E)-(1phenyl-1H-pyrazole-3,5-diyl)bis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 2) and 4,4'-((1E,1'E)-(isoxazole-3,5-diylbis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 3) with good yields.
