Application of Anderson- Schulz- Flory (ASF) Equation in the Product Distribution of Slurry Phase FT Synthesis with Nanosized Iron Catalysts Akram Tavakoli Araghi, Morteza Sohrabi∗ , Ali Kargari AmirKabir University of Technology , Faculty of Chemical Engineering, Tehran 15914, Iran Abstract Application of ASF equation on the product distribution of Fischer-Tropsch (FT) synthesis, using nanosized iron catalysts has been studied. The dependencies of product distribution on the reaction temperature and reduction conditions of nanocatalysts are investigated by the growth probability of hydrocarbons (α). The latter has been calculated for three different FT catalysts under various operating conditions and hydrocarbon ranges (n). Since ASF equation may not be suitable for these systems, a new approach has been put forward. According to such an approach the molar product distribution is applied to calculate α values from the slopes of the plots of ln( mo%/n) against n . These are called the quasi-ASF plots. Quasi-ASF plots follow the same trends as those of ASF but with an improved linearity. ∗ Corresponding author: Tel.: +982164543155; fax: +982166405847; E-mail address: sohrabi@aut.ac.ir * Manuscript
