ABSTRACT:

Within the framework of this thesis a novel method was used for fixing transition metal complexes on a carrier, and the properties of such heterogenized complexes are precursors for Fischer-Tropsch catalysts were investigated. The hydridic carbonyl complexes HCO(CO) sub 4 , HRuCo sub 3 (CO) sub 12 and HFeCo sub 3 (CO) sub 12 react with amine-modified silica gels in an acid-base reaction to produce surface-bound ammonium salts without the deposition of by-products. By decarbonylation in a stream of hydrogen, a highly active metal carrier catalyst for Fischer-Tropsch synthesis is produced. X-ray diffraction and raster electron microscopic analysis revealed that the metal is present in highly dispersed, amorphous, form on the carrier surface. All catalyst systems have in common the pronounced tendency to form methane and straight-chained hydrocarbons with high proportions of olefins. (ERA citation 09:049579)
