Highly Efficient Biomass Utilization with Solid Oxide Fuel Cell Technology

Biodiesel Fuels Conversion to Hydrogen-Rich Gas and Electricity With Solid Oxide Fuel Cell Technology

“…Nearly no carbon was observed at 800 o C in the case of Palm-BDF, whereas the other BDFs had led to significant amount of carbon on the anode surface. Carbon deposition tended to be more significant at lower operational temperatures and at higher content of unsaturated FAMEs in BDFs [10]. Severe carbon deposition occurred only on the surface of the anode, where it is most susceptible to coking, due to high concentration of long chain hydrocarbons or low S/C [14].…”

“…Reactions 7 and 8 are endothermic gasification reactions of coke. While S/C = 3.5 is thermodynamically out of the carbon deposition region [9][10], the contributions of reactions 5, 7, and 8 are not negligible, when carbon is deposited on the catalyst surface. Figure 4 shows the temperature dependence of fuel conversion and gas concentrations in anodic-off gas for DIR of BDFs on SOFC anode.…”

“…Direct internal reforming (DIR) of hydrocarbon fuels has been reported including gaseous fuels such as methane [4][5], ethane [4], and butane [4,6], and liquid fuels such as n-decane [7], gasoline [8], synthetic diesel [7], crude and jet fuel oils [9]. In view of the exhaustion of fossil resources, the utilization of biomass sources as sustainable energy resources should be promoted more in large scale [10]. Biodiesel fuel (BDF) is an oxygenated fuel produced from biomass resources such as animal fat, plants, and waste-cooking oils.…”
