Jet fuel synthesis from Fischer–Tropsch product under mild hydrocracking conditions using Pt-loaded catalysts

Abstract The development of effective Pt-loaded catalysts for high jet fuelyield was investigated in hydrocracking step in the proposed conversion process from biomass to jet fuel. Screening studies of Pt-loaded catalyst supportswere performed using an autoclave in hydrocracking of n -C 28 H 58 and n -C 36 H 74 as model compounds over ten different supports loaded with Pt (Pt content: 0.5 wt%). The Pt-loaded β-type zeolite catalyst exhibited a high corresponding jet fuelyield using both feedstocks. The effect of the reaction temperature, reaction pressure, and Pt content on the hydrocracking behavior was studied in hydrocracking of n -C 36 H 74 over Pt-loaded β-type zeolite catalyst. The corresponding jet fuelyield was maximized at 250–350 °C, and 0.9–1.4 MPa, and 0.1–1.0 wt% Pt content. The liquid product with carbon numbers 5–68 was obtained as Fischer–Tropsch (FT) product through the operation of a bench-scale biomass-to- liquid(BTL) plant. The effect of the reaction temperature and reaction pressure on the hydrocracking behavior was investigated in hydrocracking of the FT product over Pt-loaded β-type zeolite catalyst (Pt content: 0.1 wt%). The corresponding jet fuelyield was the maximum value (21.5%) at 250 °C and 1.5 MPa.
