Effects of Impurities Contained in Coal-Derived Syngas on the Performance of SOFCs

ECS Transactions, 2009
Power generation tests using a single-cell SOFC fueled by coal-derived syngas were conducted under a constant voltage of -0.8 V versus air (reference). The syngas was produced in the steam gasification of pulverized coal in a laboratory-scale fluidized ...

The effects of syngas impurities on syngas fermentation to liquid fuels

Biomass and Bioenergy, 2011
Abstract Biomass gasification to generate raw syngas used in anaerobic fermentation processes is one of several emerging technologies for the production of biofuels from biomass. The gasification-fermentation process can utilize a wide variety of lignocellulosic biomass such as prairie grasses, wood chips, and paper wastes, in addition to non ...

High-Pressure Turbulent Flame Speeds and Chemical Kinetics of Syngas Blends with and without Impurities

, 2018
This Topical Report documents the first year of the project, from October 1, 2013 through September 30, 2014. Efforts for this project included experiments to characterize the atmospheric-pressure turbulent flame speed vessel over a range of operating conditions (fan speeds and turbulent length scales).

Effects of impurities on the syngas fermentation: Mechanism and future perspectives.

Bioresource Technology
In the process of syngas bioconversion into high value-added chemicals, the presence and impact of impurities must be acknowledged. The present review aims to summarize the progress regarding the effects of various impurities on the syngas fermentation, with the focus on impurity formation in gasification, its inhibition on syngas conversion and ...

Effects of coal syngas impurities on anodes of solid oxide fuel cells

Journal of Power Sources, 2008
A literature review is conducted to summarize the studies on the identification of impurities in coal syngas and their effects on the performance of Ni-yttria stabilized zirconia (Ni-YSZ) anode of solid oxide fuel cells (SOFCs). Coal syngas typically contains major species, CO, H2, CO2, H2O, CH4, N2, and H2S as well as trace impurities.

A thermodynamic study of hot syngas impurities in steel reheating furnaces – Corrosion and interaction with oxide scales

Energy, 2014
Environmental concerns lead industries to implement gasified biomass (syngas) as a promising fuel in steel reheating furnaces. The impurities of syngas as well as a combination with iron oxide scale form complex mixtures with low melting points, and might cause corrosion on steel slabs.

Degradation behaviors of SOFC due to chemical interaction between Ni-YSZ anode and trace gaseous impurities in coal syngas

Fuel Processing Technology, 2017
Abstract The influence of the selected trace species of S, Cl, and Si contained in post-CCS (Carbon Capture and Storage) hydrogen-enriched coal syngas in the EAGLE integrated gasification combined cycle with carbon capture and storage (IGCC/CCS) pilot plant on the performance of solid oxide fuel cell (SOFC) with cermet anode of NiO and yttria ...

Hot water extraction as a pretreatment for reducing syngas inorganics impurities – A parametric investigation on switchgrass and loblolly pine bark

Fuel, 2018
Abstract The effects of hot water extraction on the removal of inorganic impurities (N, S, Na, K, Mg and Ca) in biomass that are detrimental to gasification were investigated on switchgrass and loblolly pine bark. As hot water extraction severity increased from 13 to 141 h °C, the extraction liquor pH decreased from 6.0 to 4.5 for switchgrass and 3.6

Fischer–Tropsch synthesis: effect of ammonia impurities in syngas feed over a cobalt/alumina catalyst

Applied Catalysis A: General, 2013
Abstract The effect of co-fed ammonia in syngas on the performance of a traditional cobalt catalyst (platinum promoted cobalt/alumina) was investigated during Fischer–Tropsch synthesis (FTS) using a continuously stirred tank reactor (CSTR). The addition of 1, 10, 100, and 1200 ppmw (concentration of ammonia with respect to the syngas feed) of ammonia
