The synthesis of a 90% Ni/Al2O3 catalyst via solution combustion with various fuels was studied in this work. Catalysts high content the active component (i.e., nickel) were obtained as result Ni(NO3)2·6H2O and Al(NO3)3·9H2O mixtures fuel. fuels, such hexamethylenetetramine, glycine, urea, starch, citric acid, oxalic investigated. carried out furnace, temperature being raised from room to 450 °...
