Abstract

TiO₂.MgO supports with different TiO₂/MgO molar ratios (1, 1/3, 1/6, and 1/9) were prepared via the hydrothermal method and chosen as support for the 20 wt% Ni active phase. The MgO support was also modified with WO₃ and CuO for comparison. XRD, BET, SEM, H₂-TPR, and O₂-TPO analyses were conducted to estimate the structural properties of the catalysts. Examination of the BET of the catalysts showed a decreased surface area in the 18.4–63.6 m²/g range with an increasing TiO₂/MgO ratio. The TiO₂/MgO = 1/6 ratio exhibited the best performance and lifetime even after reaction for 20 h at 750 °C and GHSV = 54000 mL/g.h and was selected as the optimal ratio. The catalytic results also demonstrated that the TiO₂, WO_3, and CuO-doped Ni/MgO catalysts positively affect catalyst performance. However, due to the higher surface area and strong metal-support interaction, the Ni/TiO₂.6MgO catalyst seems to be a better choice for the glycerol dry reforming process.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
