Synthesis of Mesoporous Carbon from Merbau Wood (<i>Intsia spp.</i>) by Microwave Method as Ni Catalyst Support for α-Cellulose Hydrocracking

Abstract

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.%).

Synthesis and Characterization of Copper Impregnated Mesoporous Carbon as Heterogeneous Catalyst for Phenylacetylene Carboxylation with Carbon Dioxide

“…It can assist the loading process of active catalyst species, facilitate good reactant transport, and expand the temperature range in reaction applications. It is known that mesoporous carbon can be impregnated well with various types of metals for multiple applications such as Ag [19][20], Pd [20], Ni [21][22], Co [23], Ru [24], and Cu [25]. In addition, mesoporous carbon is also a potential material to be used as a CO2 adsorbent [26][27].…”

NiO Supported on Porous Carbon From Merbau Wood: Synthesis and Characterization

“…The significant constitutive fractions, in the term of weight of these lignocellulose materials as the use as activated carbon precursor, are the hemicellulose, cellulose, and lignin. Merbau wood as lignocellulose materials has been known to have potential as a carbon 1232 (2022) 012001 IOP Publishing doi:10.1088/1757-899X/1232/1/012001 2 precursor [13]. Because of the difference in reactivity between these components during the pyrolysis step, the study of their carbonization is rather complicated.…”

“…It has been reported that transition metals-modified dispersed to porous materials are used as a catalyst in hydrocracking reaction [18][19][20]. The benefits of this type of catalyst include the inclusion of metal acid sites and the avoidance of metal agglomeration due to the dispersal of transition metals into the porous system such as mesoporous silica [19], MCM-41 [21], and mesoporous carbon [13,18]. In this work, the main study was to investigate the catalytic performance of nickel oxide/carbon catalysts on the hydrocracking of pyrolyzed α-cellulose as a model of biomass.…”

Microwave-Assisted Preparation of Magnetic Citric Acid-Sugarcane Bagasse for Removal of Textile Dyes

“…It is reported that microwave irradiation was used in the chemical process due to the simple and clean method with high-efficiency energy. Nanoparticle materials have been prepared by microwave-assisted methods with uniform, small, narrow size distributions and high crystalline orders in comparison with nanoparticle synthesized by the conventional heating method [19][20][21]. Acid modification of material is usually conducted under a reflux condition with high temperature and long reaction time under an oil bath.…”
