Abstract

See full text

An iron-based Fischer-Tropsch catalyst comprising magnetite and characterized by integrable X-ray diffraction reflections corresponding to (311), (511), (440), and (400), such that the relative intensity of the (400) reflection to the (300) reflection is less than about 39%. A method of preparing an activated iron-based Fischer-Tropsch catalyst by providing a precipitated catalyst comprising oxides including at least iron oxide; and activating the precipitated catalyst to provide the activated iron-based Fischer-Tropsch catalyst, wherein activating the precipitated catalyst comprises exposing the precipitated catalyst to an activation gas and increasing the temperature from a first temperature to a second temperature at a ramp rate, whereby the ratio of the intensity of the (400) reflection of the activated iron-based Fischer-Tropsch catalyst to the intensity of the (311) reflection thereof is less than 38%.
