Abstract

H₂-poor bio-synthesis gas model consists of H₂ and CO of different molar H₂/CO-ratios (2.1, 1.5, and 1) were applied for a fixed bed Fischer-Tropsch (FT) reactor over Co/Al₂O₃ and Co-Re/Al₂O₃ catalysts. The FT-reaction requires a H₂/CO-molar-ratio of ∼ 2.1 above the catalyst surface. For the ratios < 2.1, a water-gas- shift activity is desired to increase the H₂/CO-ratio. With lower H₂/CO-ratios in the feed, the CO conversion and the CH₄ selectivity decreased, while the C₅₊ selectivity and C₃ (olefin/paraffin) ratio were slightly increased. However, the catalysts studied had very low water-gas-shift activities. The Re-promoted was considerably more active and selective to longer hydrocarbons. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
