INITIAL PROCESS AND SYNTHESIS GAS CONVERSION IN FISCHER-TROPSCH FUSION REACTION

Abstract

We performed a series of Fischer-Tropsch (FT) reaction experiments in a bulk reactor on Al ₂ O ₃ supported cobalt catalyst . The batch experiment was started while the low-pressure reactor (PBFR) was operating at steady state. The reaction conditions used were typical low-temperature Fischer-Tropsch synthesis (FTS) for cobalt catalyst, reaction temperature 210 ^o C, initial pressure 20 bar(g) and H ₂ /CO = 2 in the feed. For batch experiments, we varied the duration of the batch reaction between 20 minutes and 2.5 hours. We monitored the conversion for each reaction duration and compared the reaction rates with those obtained in PBFR mode. The product distribution for C1-C9 showed an increasing trend with increasing carbon number, The pressure in the reactor was monitored during the reaction and a comparison of the pressure readings with the predicted pressure showed that most of the water produced was in the liquid phase in the reactor.
