2 FT System for preparation of synthetic fuel with slurry bubble column reactor operating in two or more FT modes

摘要

The present invention is a synthetic fuel production apparatus having a slurry bubble column reactor operating in two or more modes; And its use. The slurry bubble column reactor operating in at least two modes (a) Fe: Cu: K : SiO 2 = 100: 1 ~ 10: 1 ~ 20: 10 ~ 50 weight ratio of the Fischer having-Tropsch iron-based catalyst, or for the synthesis (b ) Fischer-Tropsch synthesis iron-based catalyst with 10 to 100% of iron atoms in the phase fraction of ferrihydrite and 0 to 90% of iron atoms in the phase fraction of hematite with respect to 100% of the number of iron atoms, 250℃ ~ 280 Operate in low temperature FT mode at ℃ to produce synthetic fuel containing C ₁₉₊ as the first wax amount, and operate in high temperature FT mode at 290 ℃ ~ 350 ℃ to make C ₁₉₊ a second wax smaller than the first wax amount. While producing synthetic fuel contained in a large amount, the off-gas emission is greater than that of the low-temperature FT mode, and the synthetic fuel production device is operated in conjunction with the slurry bubble column reactor when operating in the high-temperature FT mode. It is equipped with a combustor, a heat exchanger, a power generator, or a generator that uses gas of high calorific value discharged during operation in the high-temperature FT mode.
