Title
Fischer–Tropsch synthesis over precipitated iron catalysts supported on carbon
Abstract

•Iron catalysts supported on carbon showed high activity for FT synthesis.•450 g kg−1 h−1 of total hydrocarbon STY is obtainable at 280 °C.•Ozone treatment of active carbon enhanced the catalytic stability.

Fischer–Tropsch synthesis was conducted over carbon-supported iron catalysts at 260–280 °C and 2.0 MPa. Potassium addition enhances the selectivity to liquid hydrocarbons greatly. A high space time yield of total hydrocarbons of 450 g kg−1 h−1 was attained over K-promoted active carbon-supported catalyst. Ozone treatment of the active carbon surface is found to be effective for the catalyst durability. It is inferred that enlarged average pore diameter plays an important role for the stability by the smooth extraction of the waxy products.
