System Optimization for Fischer–Tropsch Liquid Fuels Production via Solar Hybridized Dual Fluidized Bed Gasification of Solid Fuels

Abstract: A new configuration of solar hybridized dual fluidized bed (DFB) gasification process is proposed with char separation for the production of Fischer−Tropsch (FT) liquid fuels from solid fuels of biomass and/or coal. The addition of carbon capture with sequestration and FT reactor tail-gas recycle configurations is also assessed. The studied FT liquid fuels production systems are simulated by using a pseudodynamic model incorporating a year long, hourly averaged solar insolation time-series. For the case with a… Show more

“…The flow direction and flow rate of the bed materials were controlled to accommodate the variation in solar radiation. In a subsequent study, a novel configuration of solar hybridized DFB gasification process was presented with char separation for the production of Fischer-Tropsch (FT) liquids (Guo et al, 2017). Three approaches to further improve the energetic and environmental performance of the system were proposed and assessed: 1) char separation from the bubbling fluidized gasifier; 2) co-gasification of biomass and lignite; 3) FT reactor tail-gas recycle.…”

“…Despite the several solar gasifiers developed at laboratory scale, none has been scaled-up or commercialized due to the process high temperature, the large reactor volume needed to complete fuel conversion and the fluctuating syngas production. In this scenario, the integration of dual FB gasification systems with solar energy considering solid particles as energy carrier and energy storage material could represent a solution for large scale solid fuels gasification and liquid fuels production (Guo et al, 2015;Guo et al, 2017;Gómez-Barea et al, 2020;Suárez-Almeida et al, 2021).…”

“…Indirect irradiation, in which an intermediate medium is heated by solar radiation and transported to the gasifier, has less favorable heat transfer but avoids the difficulties with direct-irradiation design [1]. Three approaches have been proposed to indirectly supply the concentrated solar radiation to the reactor: (i) irradiating the reactor external side walls [8]; (ii) using a two-cavity reactor [16]; and (iii) using solid particles as heat transfer carrier [17,18].…”
