Integrating IT-SOFC and gasification combined cycle with methanation reactor and hydrogen firing for near zero-emission power generation from coal

Biomass fueling of a SOFC by integrated gasifier: Study of the effect of operating conditions on system performance

“…In the presented equations l is the air fuel ratio, which is usually in the range 2 < l < 4 [36,37] for syngas fueled SOFCs, while _ m TOT is the minimum syngas molar flow rate at the inlet SOFC section to allow for H 2 oxidation. n Concentration losses due to mass transfer limitations are taken into account according to the 0-D modeling approach and the fuel utilization.…”

Assessment of finite volume modeling approaches for intermediate temperature Solid Oxide Fuel Cells working with CO-rich syngas fuels

“…In particular we focus on the issues related to the use of syngas fuels, like those generated by coal or biomass gasification. These processes often feature high CO and/or CH 4 contents depending on the gasification technology and on the type of integration with the power cycle (see for instance the proposals for high CO gasification in Romano et al [7] as well as the studies on catalytic gasification [8] or about the use of methanation reactors in [9]). …”

The effects of gasification technology on IGFC system efficiency

“…Fuel cell owns extremely high energy density, which can transfer chemical energy of fuel to electrical energy directly, profit from that, the theoretical power efficiency of IGFC system can up to as high as 56%-58%. IGFC system also with the function of CO2 gathering, CO2 concentration of tail gas can even reach to 95%, with the help of CO2 Capture and CO2 storage (CCS) process, theoretically zero-CO2 emission could be achieved (Grol E 2009, Romano M C 2011, Lanzini A 2014. Recently years, with the development of fuel cell technology, the cost of IGFC system is falling steeply, which makes near-zero CO2 emission IGFC system the most promising coal power technology around the world.…”
