Abstract

This study proposes a method for selectively producing diesel-range hydrocarbons by combining Fischer–Tropsch synthesis (FTS) over a zeolite-supported catalyst with the oligomerization of C5–C10 alkenes over an H-Beta zeolite. FTS was carried out under gas recirculation conditions (H2/CO = 1.85, 2.0 MPa). At a recirculation ratio of 16, the diesel content in the product increased to 54.6 wt %, compared to 38.7 wt % under flow-through conditions. Finally, by oligomerizing the alkene-enriched gasoline fraction from the FTS over H-Beta-18, the overall diesel fuel content was enhanced to 69%.
