“…Gasification of biomass under with steam has attracted research attentions and a number of research works have shown that the process had great potential for large -scale development [10][11][12]. This process had strong advantage of making full use of low-grade solid fuels to produce the high economical value and cleaner products [13].…”

This work presents a comprehensive study on the steam gasification kinetics and reactivity of Miscanthus chars (MC) prepared at different temperatures (600 °C, 800 °C and 1000 °C) with the correlations to their composition and microstructure. The results showed that the order of gasification reactivity was MC600 > MC800 > MC1000, and the microcrystalline structure and the content of inherent alkali and alkaline earth metals in the MC were the main factors affecting their reactivity under steam gasification. The reactivity also increased with the increase of gasification temperature, and the effect of gasification temperature on the reactivity of MC was far greater than that of the char production temperature. High heating rate could also effectively promote the gasification reactivity of MC. The kinetics of the steam gasification process were analyzed by different modelling methods. The Random pore model (RPM), among the three methods compared, was the most suitable one to describe the kinetics of isothermal gasification process, of which, the activation energies were in the range of 176-203 kJ/mol with a good kinetic compensation effect between activation energy and pre-exponential factor. The master-plots method proved that the F 2 mechanism was suitable for describing the early stage (X<50%) of the MC gasification reaction, and the D 1 mechanism was suitable to the late stage (X >50%) of the MC gasification process.

“…They are easily adaptable to various industrial power plant scales. In addition, SOFC runs at a high temperature (600 °C) and cogenerates high-quality heat or steam that can be used as an additional heat source (6). Considering that the maximum fuel utilization for SOFC is approximately 85%, a burner is necessary for the oxidation of unconverted fuels.…”

To meet “net zero” emission target for greenhouse gases in the year 2050, it is essential to retrieve most of the produced CO2 from emission intensive activities and store it permanently underground. This study considers integration of a 10 kW solid oxide fuel cell (SOFC) system with vacuum pressure swing adsorption (VPSA). In the integrated system, a small amount of electricity needed for the VPSA directly comes from SOFC system. The oxygen produced by VPSA is used to complete the oxidation of the unconverted fuel from the anodic side of SOFC, and then CO2 is separated automatically after the water condensation. Moreover, in this study, SOFC with VPSA has been optimized for minimizing the energy requirement and number of heat exchangers. Eight heat exchangers have been sized. Finally, the integrated system has waste heat available, to valorise the waste heat of the system, a steam cycle has been integrated for producing around additional electricity, to improve the overall efficiency. Finally, economic analysis has been performed, to understand its market competitiveness.

“…In addition, the IGFC system offers a very low specific CO 2 emission as compared to the traditional co-gasification power plant. Detchusananard et al (2019) simulated the integration of the sorption enhanced steam biomass gasification (SEG) with SOFC and a CHP system and they highlighted that a maximum exergy efficiency of 61.2% can be achieved.…”

Biochar derived from pyrolysis or gasification has been gaining significant attention in the recent years due to its potential wide applications for the development of negative emissions technologies. A new concept was developed for biochar and power co-generation system using a combination of biomass pyrolysis (BP) unit, solid oxide fuel cells (SOFCs), and a combined heat and power (CHP) system. A set of detailed experimental data of pyrolysis product yields was established in Aspen Plus to model the BP process. The impacts of various operating parameters including current density (j), fuel utilization factor (Uf), pyrolysis gas reforming temperature (Treformer), and biochar split ratio (Rbiochar) on the SOFC and overall system performances in terms of energy and exergy analyses were evaluated. The simulation results indicated that increasing the Uf, Treformer, and Rbiochar can favorably improve the performances of the BP-SOFC-CHP system. As a whole, the overall electrical, energy and exergy efficiencies of the BP-SOFC-CHP system were in the range of 8–14%, 76–78%, and 71–74%, respectively. From the viewpoint of energy balance, burning the reformed pyrolysis gas can supply enough energy demand for the process to achieve a stand-alone BP-SOFC-CHP plant. In case of a stand-alone system, the overall electrical, energy and exergy efficiencies were 5.4, 63.9 and 57.8%, respectively, with a biochar yield of 31.6%.
