Biofuel Production Using a Staged Fischer-Tropsch Process Followed by Mild Hydrocracking

Short Introductive summary

The Horizon 2020 PULP&FUEL project (2018-2022, grant agreement No 818011) investigates the integration of biofuel production with a pulp mill. Dry gasification will provide the backbone for syngas production and super critical water gasification (SCWG) of weak black liquor aims to produce hydrogen to minimize the sacrificial conversion of CO to obtain the proper H2/CO ratio for FT. Using a staged approach to a fixed-bed FT process, utilizing H2 from SCWG, it is possible to achieve high overall carbon conversion while operating the first FT reactor with a Co-catalyst and with 1 H2/CO 2, minimizing the initial sacrificial conversion of CO in the shift process. By operating the second reactor using an Fe-based catalyst, the overall product spectrum is moderated due to the inherent differences in selectivity. Mild hydrotreatment/hydrocracking converts the syncrude to transportation range biofuels.
