Popis: A new method is described for the preparation of catalysts by means of impregnation. The technique is especially suitable for obtaining a homogeneous distribution of the active material within preshaped support particles. The possibilities of the new procedure are illustrated by impregnation of preshaped α-alumina pellets with various organometallic Sncomplexes. After calcination in air the size and distribution of the resulting SnO2 particles and the surface area and porous structure of the catalysts were investigated by several complementary techniques such as BET surface area measurements, mercury porosimetry, X-ray diffraction, electronmicroscopy and temperature-programmed reduction. It proved possible to control the mean particle size and the porosity within narrow limits.
