Abstract: This paper introduced the RIPP`s low temperature F-T synthetic oil hydro-upgrading CFHL technology and its commercialization. The operating conditions on the effect of iso-hydrocracking reactions were explored. The results show that temperature, hydrogen pressure and space velocity significantly influence the iso-hydrocracking reaction, while the effect of H2/oil ratio is much less. The industrial application of CFHL shows that the cetane number of the hydrotreated diesel is 81 and the freezing point is below -20 ℃. The selectivity of iso-hydrocracking diesel exceeds 82.2%, while the cetane number of iso-hydrocracking diesel is 76 with a freezing point below -53 ℃.

Key words: F-T synthetic oil, hydroupgrading, isocracking, industrialization
