Direct internal reforming (DIR) operation of a solid oxide fuel cell (SOFC) is a very attractive concept for downsizing and cost reduction of SOFC systems. This study aimed to develop stable operation of a DIR-SOFC fuelled by biogas. The current-voltage (I-V) curves of 2 x 2 cm 2 planar SOFCs (anode-and electrolyte-supported cells, ASC and ESC, respectively.) were measured at 800 °C in the direct feed of a simulated biogas mixture (CH4/CO2 = 1), and the flexible structured catalyst material (paper-structured catalyst (PSC)) was applied on the anode material for performance enhancement. By applying a hydrotalcite (HT)-dispersed PSC (HT-PSC), the sulfur tolerance of the SOFC in the DIR operation was remarkably improved. By the effect of the HT-PSC, for both ASC and ESC, a stable cell voltage higher than 800 mV was obtained over 200 h at 0.2 A cm-2 in the direct feed of simulated biogas under 5 ppm H2S poisoning.

“…Transitional metals which composed of various acids and bases are now commonly used. Typical examples of those transitional metals commonly used include in biodiesel production include MnO, ZnO, TiO, WO and ZrO [15]. Amongst the transitional metals, Lanthanum contains complexes that produces many doles with high surface area, small crystal size and high number of basic sites [16].…”

“…However, when molybdenum bearing minerals get in contact with oxygen and water, the resulting molybdate ion MoO 2− 4 is quite soluble. Industrially, molybdenum compounds (about 14% of world production of the element) are used in high-pressure and high-temperature applications [15]. In this study sodium molybdate (Na 2 MoO 4 ) has been synthesized and investigated as a heterogeneous catalyst for producing biodiesel from Camelina sativa seed oil.…”

Sodium molybdate (Na2MoO4) has been synthesized and investigated as a heterogeneous solid catalyst for biodiesel from Camelina sativa seed oil. Transesterification reactions occurred under atmospheric conditions with relatively, low temperature short reaction time and normal pressure. The prepared catalyst was characterised by means of SEM, TGA, UV, XRD and FTIR. The properties of the biodiesel were compared with international standards. The transesterification reaction was very efficient with the optimum yield higher than 95% at methanol to oil molar ratio of 17:1, catalyst amount of 6%, reaction temperature of 60 °C and reaction time of 2.5 h. The molybdate complex had a high Lewis acidity and most certainly act as alcohol O–H bond leading to a transient species which has high nucleophilic character. The catalyst was easily recovered and after being washed for three times, showed capacity of recyclability for another catalytic reaction of five cycles with similar activity. The properties of the biodiesel were comparable to international standards.

The present study investigates the distributed generation of hydrogen (50 Nm 3 /h) by steam reforming of biodiesel. The system comprises a steam reformer, a water gas shift stage, a pressure swing adsorption unit and a dual fuel burner. Sensitivity analysis with Aspen Plus shows a positive effect on overall system efficiency for high pressure and a low steam-tocarbon ratio. A theoretical maximum efficiency (based on lower heating value) of 78.2 % can be obtained requiring a complex and costly heat exchanger network. Consequently, a system simplification is proposed resulting in a novel fuel processor concept for steam reforming of biodiesel based on a fully heat integrated system. A thermal system efficiency of 75.6 % is obtained at S/C=2.53, p=13 bara and T Ref =825 °C. The techno-economic evaluation reveals hydrogen production costs ranging from 7.25 €/kg to 10.58 €/kg.
