摘要	Low-temperature Fischer-Tropsch synthesis (LTFTS) is one of the green routes for liquid fuel production. We prepared nanocrystalline Fe-B catalysts with different particle sizes and microstructures by adjusting the addition sequence of the precursors. In situ carburization of the Fe-B catalysts at 423 K revealed that the addition sequence influenced the rate and degree of carburization pronouncedly. In LTFTS at 423 K, the Fe-B catalysts displayed similar, markedly high selectivity to liquid fuels, with similar to 48% for C-5-C-11 (gasoline fraction) and similar to 31% for C-12-C-20 (diesel fraction) hydrocarbons, and low selectivities to CO2 and CH4, manifesting excellent carbon atom economy over the non-noble Fe-B catalysts. While the carburization degree did not affect the product distribution, the activities of the Fe-B catalysts evolved positively with the epsilon-Fe2C content. Moreover, a good linear relationship was established between the Fe-Fe coordination number and the epsilon-Fe2C content. (C) 2016 Elsevier Inc. All rights reserved.
