Abstract
In this study, two Ni/C-type catalysts were tested for CO₂ methanation. A series of experiments supported optimization of the catalysts’ operating conditions and evaluation of their maximum performance. The carbon-based materials were obtained via pyrolysis of dried leaves of maple and Japanese knotweed. Nickel particles were deposited onto the carbon supports using a wet impregnation method with a nickel nitrate solution. The obtained nickel/carbon composites were tested in a single-stage flow reactor connected to a gas chromatograph for measuring methane yield under different reactant flow rates, pressure and temperature. SEM–EDS and MP-AES techniques were used to determine nickel distribution on the support surface and chemical composition of the catalysts after hydrogen activation, as well as after methanation under optimal operating conditions. The catalyst supported on maple leaves-derived carbon demonstrated high Ni dispersion and content across the carbon surface both before and after methanation. It also exhibited a high performance, achieving a maximum methane yield of 78% during a 1.5-hour test and maintaining a stable methane yield of 65% over a 10-hour operation. These results indicate that this catalyst exhibits a promising short-term catalytic performance and may be taken into consideration for potential industrial applications in the future.
