This paper investigates the equilibrium species and theoretical electromotive forces (EMF) of cell fed with 3% H 2 O humidified simulated underground coal gasification (UCG) gas, and the performance of anode-supported NiO-Gd 0.1 Ce 0.9 O 2-δ (GDC)||GDC||Ba 0.9 Co 0.7 Fe 0.2 Nb 0.1 O 3-δ (B 0.9 CFN) cell operated on the UCG gas. Results show that EMF values are always above 1.05 V, and the UCG gas fed cell exhibits maximum power densities of 0.151, 0.299, 0.537 and 0.729 W·cm -2 at 500, 550, 600 and 650 o C, respectively, slightly inferior to that of hydrogen fed cell of 0.330, 0.544, 0.765 and 0.936 W·cm -2 , respectively, as a result of sluggish reaction kinetics of UCG gas at the anode. However, the synergy between slow anode reaction kinetics and sufficient and fast migration of oxygen ions to the anode attributing to the using of GDC electrolyte and B 0.9 CFN cathode suppresses carbon deposition at intermediate temperatures. Only slight current density decrease ranged from 0.2959 to 0.2790 A·cm -2 is observed during the 480 h of durability testing under constant 0.7 V output voltage at 600 o C for the UCG gas fed cell. And subsequent * Corresponding author. Tel.2 SEM inspection of the tested cell indicates no measurable carbon deposition on the anode surface, thereby demonstrating that UCG gas is a promising fuel for utilization in SOFCs.

“…The cyclone can only be considered a pretreatment and be used upstream of a technology able to remove small particles (< 5 µm). In the biomass gasification pilot units using a cyclone, it was coupled with either a ceramic candle filter [19] or a sintered metal filter [20], providing particle filtration efficiency close to 100%.…”

“…Depending on the alloy used in the candles, they can be operated at temperatures up to 1000°C. However, temperatures reported in the literature are between 400 and 700°C [7,20,22]. Metal filters like ceramic filters form a residual particle deposit.…”

, et al.. Separation of particles from syngas at high-temperatures with an electrostatic precipitator. Separation and Purification Technology, Elsevier, 2012, 92, pp.181 -190. 10 The study, which is submit to you, was supported by the French National Agency and it is incorporated in the EPURGAZ project (ANR-06-BIOE-O05). The aim of this project was to study the different existing possible way to clean syngas from biomass gasification at high temperatures (> 500°C). This project was realized in partnership with the French Institute of Petrol (IFP -Lyon), the French Atomic Energy Commission (CEA -Grenoble), Air Liquid (Loges en Josas) and the Savoie University.This study shown the possibility to use an electrostatic precipitator at temperatures above 500°C to remove the particles contained in syngas from biomass gasification. Indeed, the filtration efficiency obtained during the filtration tests conducted at the CEA site in Grenoble, FRANCE, were greater than 95%.I submit you only 2 reviewers because I did not find an others :  The possibility of removing the particles from syngas at high temperature with an electrostatic precipitator (>500°C) was studied. Syngas filtration tests conducted directly downstream of a gasifier. Two filtration tests were realized : the first at a temperature of 510°C and the second at 680°C. For each filtration tests, an average mass filtration efficiency greater than 95% was obtained. Grenoble Cedex 9, FRANCE Abstract-The synthesis gas stemming from biomass gasification contains particles (ashes, soot, etc.), which, if not removed, can induce severe operational damage. The problem is more serious if syngas must be used for chemical synthesis as in the Fischer-Tropsch catalyst reaction or the water-gas shift. The particles contained in syngas can reduce or inhibit the catalyst effect. Moreover, for energy reasons, it is also necessary to develop a filtration process at as high a temperature as possible. To address this issue, a study to show the possibility of removing the particles from syngas with an electrostatic precipitator at high temperature (500-1000°C) and pressure (0.1-1 MPa) was conducted. Syngas filtration tests conducted directly downstream of a gasifier demonstrated the feasibility of implementing an electrostatic precipitator to clean syngas at temperatures above 500°C.
