Highly efficient and selective hydrogenation of a,b-unsaturated carbonyl compounds to unsaturated alcohol using bimetallic palladium-copper supported on carbon (denoted as Pd-Cu(3.0)/C; 3.0 is Pd/Cu molar ratio) catalyst is demonstrated. Pd-Cu(3.0)/C catalyst was prepared via a simple hydrothermal route under air atmosphere at 150 °C for 24 h followed by reduction with hydrogen at 400°C for 1.5 h. The chemoselective hydrogenation of typical a,b-unsaturated carbonyl ketone (2-cyclohexene-1-one) and aldehyde (trans-2-hexenaldehyde), and chemoselective hydrogenation of FFald and (E)-non-3-en-2-one mixture demonstrated high productivity, leading to high selectivity of unsaturated alcohols. The presence of bimetallic Pd-Cu alloy phase with relatively high H2 uptakes was observed, enabling to preferentially hydrogenate C=O rather than to C=C bonds under mild reaction conditions. Pd-Cu(3.0)/C catalyst was found to stable and reusable for at least four reaction runs and the activity and selectivity of the catalyst can be restored to the original after rejuvenation with H2 at 400 °C for 1.5 h.

Inexpensive Raney Ni-clay composite (R-Ni/clay) catalysts exhibited excellent activity and reusability in the total hydrogenation of biomass-derived furfural into tetrahydrofurfuryl alcohol under mild conditions. For the Raney Ni-bentonite (R-Ni/BNT) catalysts, the complete reaction was achieved at 393 K, 180 min giving almost 99% yield of tetrahydrofurfuryl alcohol. The R-Ni/BNT catalyst was found to be reusable without any significant loss of activity and selectivity for at least six consecutive runs.

Publisher : Universitas Gadjah Mada

Preparation of a kaolin-hydroxyl chromium composite and characterization of its physico-chemical properties were conducted. The olygomer hydroxyl-chromium was prepared by adding Na2CO3 to 0.1 M chromium nitrate solution (ratio OH/Cr = 2) and then dried at 110 oC and 400 oC for 4 h. Characterization of kaolin-hydroxyl chromium composite includes determination of acidity, functional groups, basal spacing, and surface area (BET-N2 sorption analyzer). The result showed that intercalation of hydroxyl chromium resulted in the decreasing of basal spacing but increased the specific surface area of kaolin. Drying of the intercalated kaolin at 400 oC decreased surface area, total volume pore and pore radius. FT-IR spectra showed that hydroxyl-chromium detected at wavelength of 2925 and 2855 cm-1.

ACTIVITY TEST AND REGENERATION OF NiMo/Z CATALYST FOR HYDROCRACKING OF WASTE PLASTIC FRACTION TO GASOLINE FRACTION Rodiansono Rodiansono; Wega Trisunaryanti
Indonesian Journal of Chemistry Vol 5, No 3 (2005)
Publisher : Universitas Gadjah Mada

Activity test and regeneration of NiMo/active natural zeolite catalyst for hydrocracking of waste plastic fraction of polyprophylene (PP) type have been carried out. The catalysts was prepared by loading Mo followed by Ni Metals onto the natural zeolite (Z) sample, then calcined at 500oC, oxidized and reduced at 400oC under nitrogen, oxygen and hydrogen stream, respectively. The characterization of catalysts including spesific surface area, average pore radius, and total pore volume were performed by gas sorption analyzer, amount of total acid sites was determined by gas sorption method, and acid site strength was confirmed by IR spectroscopy. The hydrocracking process was carried out in a semi-flow reactor system at 360 oC and catalyst:feed ratio 0.5 under hydrogen stream (150 mL/hour). The feed was vaporized from the pyrolisis reactor into the hydrocracking reactor. A liquid product was collected and analyzed by gas chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS). The characterization results showed that spesific surface area, average pore radius, and total pore volume of the Z sample decreased after loading of the Ni and Mo metals. Amount of total acid sites of the NiMo/Z catalyst was higher than that of the Z sample. The activity of NiMo/Z catalyst decreased after several continously runs. Its regeneration produced the NiMo/Z reg catalyst with similar activity and selectivity to the fresh catalyst (NiMo/Z). The activity of catalysts at the optimum condition followed the order of NiMo/Z reg>NiMo/Z>Z (conversion of hydrocarbon C>12) and NiMo/Z reg>NiMo/Z>Z (total yield of gasoline fraction). The selectivity of catalysts for C7-C8 product followed the order of Z>NiMo/Z>NiMo/Z reg.

Selective hydrogenation of sugars (e.g. sucrose, cellobiose, glucose, fructose, xylose, arabinose) into sugar alcohols (sorbitol, mannitol, xylitol, arabitol) can be achieved by means of supported Raney Ni-based catalysts. Various supporting materials such as the layered structure of clay (e.g. bentonite, taeniolite, smectite), metal oxides (e.g. Nb2O5, ZrO2, Al2O3), and conventional supports (e.g. carbon, silica, zeolite (JRC-SZ1)) were employed to obtain high performance of supported Raney Ni-based catalysts. The conventional Raney Ni, Raney Ni/AlOH, and Ni-NP with relatively high dispersion exhibited superior catalytic activity compared with the various supported Raney Ni catalysts with the conversion of 100% and hexitols selectivity almost ~99%. The H2 treatment of Raney Ni/SMT at a temperature of 473–773 K caused the increase in Ni(111) crystallite sizes as the conversion of sucrose with compromised decreased of hexitols product. The presence of acidic co-catalyst such as SnO, amberlyst-15, JRC-SZ1, JRC-Z5-9OH1 on Raney Ni/AlOH catalyst significantly enhanced the formation of glycerol product even though the conversion of sucrose compromised decreased owing to the partial leaching of Ni metal into the reaction mixture.

Katalis hasil preparasi dikarakterisasi meliputi keasaman (ammonia dan pyridine), luas permukaan, volume pori menggunakan metode adsorpsi isotermal N2 (BET), difraksi sinar-X (XRD) and SEM (scanning electron microscopy). Hasil karakterisasi menunjukkan bahwa katalis logam Ni, Co dan Ni-Co telah berhasil dipreparasi menggunakan metode matrik polimer dengan tingkat keasaman tertinggi pada Co/zeolite-ZCP-50 (monometallic), dan Ni-Co/zeolite-ZCP-50 untuk katalis bimetallic. Penambahan ZCP-50 pada zeolit memberikan kontribusi yang besar pada luas permukaan spesifik, rerata jejari pori dan volume total pori. Tingkat dispersi logam pada permukaan padatan pengemban zeolite-ZCP-50 lebih baik dibandingkan dengan zeolite asal. Kata kunci: katalis, Ni dan Co, zeolit, ZCP-50, pengemban hybrid

Telah dilakukan pembuatan biodiesel melalui reaksi transesterifikasi metanol dan minyak sawit menggunakan pelarut petroleum benzin dan katalis KOH. Reaksi dilakukan pada temperatur 60oC dengan waktu reaksi 25 menit yang dilakukan secara bertahap (tahap pertama 15 menit dan tahap kedua 10 menit). Variabel dalam penelitian ini adalah perbandingan mol metanol/minyak sawit (3:1, 6:1, dan 9:1) dan perbandingan volume pelarut terhadap volume minyak sawit (0,2; 0,4; 0,6; 0,8; 1,0; dan 1,2). Penentuan perbandingan mol dan volume pelarut optimum didasarkan pada karakteristik biodiesel, yaitu: bilangan asam, viskositas kinematik, berat jenis, dan kadar air. Karakteristik biodiesel hasil penelitian selanjutnya dibandingkan dengan karakteristik biodiesel berdasarkan standar ASTM dan FBI. Hasil penelitian menunjukkan bahwa petroleum benzin dapat digunakan sebagai pelarut pada pembuatan biodiesel. Kondisi optimum diperoleh pada perbandingan mol metanol/minyak sawit 6:1, sedangkan perbandingan volume pelarut/minyak sawit optimum pada 0,2 (v/v). Kata kunci : transesterifikasi, minyak sawit, pelarut, petroleum benzin.
