Summary The tail gas of Fischer‐Tropsch synthesis (FTS) contains unconverted syngas and gaseous hydrocarbons. It is usually treated at a high‐cost and low‐efficiency method, whereas it is a feasible fuel for solid oxide fuel cells (SOFCs). Herein, we evaluated the carbon deposition temperature of the FTS tail gas obtained at various reactor pressures. Thermodynamic calculation showed that the FTS tail gas could be used in SOFCs without the risk of carbon deposition. By adding 5% water, the initial non‐carbon deposition temperature was dropped from 830°C (without water co‐feeding) to 720°C. Under reforming, the syngas (H2/CO) ratio is about 2 when it reaches equilibrium states, which can be recycled back into the FTS process. Theoretically, a current of 6.5‐7.1 A per 100 mL FTS tail gas could be generated by the SOFC. This study demonstrates that it is promising to use the FTS tail gas as a carbon‐containing fuel for SOFCs. Highlights A new concept of the utilization of FTS tail gas as a fuel in a SOFC is developed. FTS tail gas can convert to syngas with H2/CO = 2 that can be recycled back into FTS. Co‐feeding water into FTS tail gas reduces the non‐carbon deposition temperature. Theoretical current densities proved the FTS tail gas is a promising fuel for SOFCs.

“…The existence of a broad absorption band between 4000 and 3200 cm −1 could be due to the O–H stretching of the hydroxyl group from carboxylic group bonding or water. However, a wavenumber between 3760 and 3520 cm −1 has been selected for CO2 ( Chlipaa et al., 2019 ) identified in biogas. Moreover, a wavenumber in the region of 3250-2650 cm −1 has been assigned to methane (CH 4 ).…”

“…It can be seen that the functional groups in this region are dominated by aliphatic alkyl and methylene with C–H vibrational stretching. In the absorption band of wavelength 2143 cm −1 , CO has been reported ( Chlipaa et al., 2019 ). Similarly, the region having a wavenumber 2150–1865 contains a functional group with a C=O stretching vibration.…”

“…En Ecuador, la vinaza residual de la obtención del alcohol etílico se está procesando en los digestores anaeróbicos para producir biogás [1], con un contenido de metano (CH4), comprendido entre un 45 % y un 70 %; de dióxido de carbono (CO2), entre un 30 % y un 40 %; de sulfuro de hidrógeno (H2S), entre un 2 % y un 4 %, y alrededor de un 2 % de otros gases [2], [3]. Desde el punto de vista económico, al utilizar biogás disminuye el consumo de combustibles de origen fósil, lo que genera una opción altamente rentable por la utilización de energía autogenerada y sostenible, con un efecto directo al costo en el proceso productivo [4].…”

En este artículo se estudió la capacidad de una arcilla ecuatoriana, modificada con sodio, cobre y zinc y adaptada morfológicamente ala forma de extrudados para remover sulfuro de hidrógeno de biogás (H2S). Esta capacidad se evaluó empleando un filtro de lecho fijo que contenía los extrudados acoplado a una corriente biogás, con 2,2% de H2S, y un flujo de 1mL/s, a una presión manométrica de 2 psig, temperatura ambiente de 30oC. La corriente de biogás provenía de un biorreactor anaeróbico de tratamiento de vinaza. La concentración de H2S a la entrada y la salida del filtro fue determinada, mediante ampollas GASTEC 4H y 4HH, emplenado una bomba de aspiración TGASTEC GV-100-S-TR. Los mejores resultados se obtuvieron con el sólido ST15% Na 15%Cu15%Zn, el cual mantuvo sus carecteríticas de sorción por 920 min antes de saturarse, removiendo 2,84 mmol de H2S/g de sorbente. Entre tanto , el carbón activado industrial, empleado para la reducción de la concentración H2S, presentó una capacidad de remoción de 2,58 mmol de H2S/g de carbón y se saturó a los 540 min.
