Review
A method of preparation Ni/γ-alumina egg-shell type catalysts with high metal content was developed. The method is based on impregnation of alumina particles with concentrated solution of inorganic Ni salt (nitrate) in selected organic solvents. The method takes advantage from the fact that volatile organic solvents can be quickly evaporated so there is a chance to concentrate Ni to a very thin layer below the particle surface. Impregnation with water solution of Ni salt appeared to be ineffective.
