Abstract

Gas-to-liquids (GTL) is a viable pathway for synthesis of clean fuels from natural gas. One of the attractive synthesis options is the Fischer-Tropsch (F-T) method using an iron catalyst to yield a broad range of hydrocarbons. We collected catalyst samples during three separate F-T runs that utilized nanophase (mean particle diameter (MPD): 3 nm and 20-80 nm) and micrometer-sized (32.5 μm) Fe₂O₃ that served as catalyst precursors. The collected samples were characterized with micro-X-ray fluorescence and computed microtomography at the National Synchrotron Light Source (NSLS). Results found with two different measurement techniques indicated that there was heterogeneity on a spatial scale corresponding to volumes of roughly 10 ³ μm³.
