Modification of preparation technique for highly dispersed Ni/γ?Al2O3 catalysts

Highly dispersed Ni/–Al₂O₃ catalysts have been prepared by the method of double impregnation. The application of ethylenediaminetetraacetic acid (H₄Y) as a chelating agent for activation of the -Al₂O₃ support enables us to prepare highly dispersed Ni/Al₂O₃ catalysts. The use of this chelating agent according to the described modification of the impregnation technique results in the highest dispersity of the metal component in the catalysts obtained.
