Abstract

Highly dispersed nickel alumina supported catalysts have been prepared by the method of double impregnation. Application of an EDTA-type chelating agent in the first step of impregnation resulted in high metal dispersion in an active phase of the reduced catalysts. Results obtained from recorded spectras by Fourier transform infrared spectroscopy (FTIR) suggests chelating compound adsorption on alumina surface in the way of interaction between electron pairs on nitrogens and protonated surface hydroxyl groups.
