Estimation of the Efficiency of Oxalic Acid in the Solution Combustion Synthesis of a Catalyst for Production of Hydrogen and Carbon from Methane

The parameters of the synthesis of catalysts by the solution combustion method using oxalic acid as a reducing agent were investigated. The activity of the catalysts was determined in the production of hydrogen and carbon nanofibers by the catalytic decomposition of methane. The efficiency of oxalic acid was demonstrated in the preparation of a nickel catalyst (90% Ni/10% Al2O3), which does not require the preliminary reduction with hydrogen. Regression analysis identified that the yields of carbon and hydrogen are most strongly affected by temperature among other synthesis parameters.

Automated summary

The parameters of catalyst synthesis using oxalic acid as a reducing agent in the solution combustion method were investigated. The activity of the catalysts in the catalytic decomposition of methane to produce hydrogen and carbon nanofibers was determined. Among the synthesis parameters, temperature was found to have the strongest impact on the yields of carbon and hydrogen. The efficiency of oxalic acid in the preparation of a nickel catalyst (90% Ni/10% Al2O3) without the need for hydrogen reduction was demonstrated.
