  3. Abstract:
  4. The importance of the gas-to-liquid process is increasing due to growing demand for a high quality, less expensive, and cleaner fuel. Faujasite zeolites, e.g,. zeolites type X and Y, are well-known catalysts in the petrochemical industry. Faujasitic supports (mainly X zeolites) were prepared via hydrothermal synthesis with different Si/Al ratios from pure chemical materials and fly ash as a source of silicon. A high quantity of cobalt oxides was deposited on supports by varying samples Si/Al ratios during the zeolite preparation procedure. Using fly ash in synthesizing the zeolitic support resulted in a A-X zeolite material with a very high cation exchange capability and final cobalt content. The stability of this zolite structure was confirmed against the chemical and thermal treatments employed during catalyst preparation. The increase of catalytic samples mean pore diameters in comparison with preliminary faujasitic materials might be due to cobalt oxide particles encapsulation and growth inside the micropores of the support. This is an abstract of a paper presented at the 18th International Congress of Chemical and Process Engineering (Prague, Czech Republic 8/24-28/2008)
