Abstract:
Nickel catalysts supported on modified alumina were synthesized, their physicochemical properties and activity in the reaction of autothermal reforming of methane (ATR CH4) were studied. Regulation of physicochemical and, consequently, functional properties of the samples was performed by the modification of (γ+δ)-Al2O3 support with the additives of different composition Ce1-xMxOy (M = Gd, La, Mg; x = 0, 0.2, 0.5, 0.8 and 1; 1 ≤ y ≤ 2) in the amount of 10 mass %. It is shown that Ni/Ce1-xMxOy/Al2O3 are mesoporous materials with specific surface area 80 ± 5 m2/g, slightly changing with the variations of the composition of modifying additive. The phases of alumina (γ+δ)-Al2O3, fluorite-like solid solution based on СеО2 with an average crystallite size 9.0 ± 1.5 nm and nickel oxide NiO are present in the catalysts. The average size of NiO particles is varied in the range from 6.0 to 13.5 nm and is determined by the composition of modifying additive, decreasing with an increase of x, and in the following sequence of oxide additives: CeO2 > MgО > Gd2О3 > La2O3. The catalysts are capable of self-activation under the ATR CH4 reaction conditions, and this effect is enhanced in the following row of M: Mg < Gd < La, which is in good correlation with the reducibility of samples. The optimal catalyst Ni/Се0.5La0.5O1.75/Al2O3 is revealed, providing the hydrogen yield of 80 % upon 100 % methane conversion at 850 oС. The use of the developed catalysts for the energy-effective conversion of natural and associated petroleum gases into the hydrogen-containing gas is promising.
