Low cost and renewable HS-biofilter inoculated with .

The use of biogas to produce hydrogen is currently gaining more attention. One of the drawbacks for the valorization of biogas is the presence of HS, a hazardous molecule that can cause damage in the metallic internal structures of industries. In this study, the HS-removal performance of a fungi-based biofilter was investigated.

Evaluation of a Catalyst Durability in Absence and Presence of Toluene Impurity: Case of the Material CoNiMgAl Mixed Oxide Prepared by Hydrotalcite Route in Methane Dry Reforming to Produce Energy.

Ni, Co, Mg, and Al mixed-oxide solids, synthesized via the hydrotalcite route, were investigated in previous works toward the dry reforming of methane for hydrogen production. The oxide CoNiMgAl calcined at 800 °C, CoNiMgAl800, showed the highest catalytic activity in the studied series, which was ascribable to an interaction between Ni and Co, which is optimal for this Co/Ni ratio. In the present study, CoNiMgAl800 was compared to a commercial catalyst widely used in the industry, Ni(50%)/AlO, and showed better activity despite its lower number of active sites, as well as lower amounts of carbon on its surface, i.

Detection of adsorbed O species on CeO solid impregnated with Ag ions during its thermal treatment under a H atmosphere, an EPR study.

10% Ag/CeO solid was prepared by the impregnation method. When the solid is calcined at 400 °C, three types of Ag species are formed. One of them is more thermally stable compared to the others.

Influence of the presence of ruthenium on the activity and stability of Co-Mg-Al-based catalysts in CO reforming of methane for syngas production.

Hydrogen production by methane dry reforming is an important yet challenging process. A performing catalyst will favor the thermodynamic equilibrium while ensuring good hydrogen selectivity. We hereby report the synthesis of Co Mg Al (with x = 2 and 6) mixed oxide catalysts synthesized via hydrotalcite precursors and the synthesis of a ruthenium-based catalyst on a cobalt, magnesium, and aluminum mixed oxide supports Ru/Co Mg Al (with x = 2 and 6).

Steam reforming of ethanol for hydrogen production over Cu/Co-Mg-Al-based catalysts prepared by hydrotalcite route.

The performances of different 5Cu/CoMgAl (x = 0; 2; 4; 6) catalysts prepared by the wet impregnation method were investigated in the ethanol steam-reforming reaction (ESR) at 450 °C during 4 h under a steam/ethanol ratio of 3 (S/E = 3). The best catalyst among the prepared solids was 5Cu/CoAl as it showed a complete ethanol conversion and the highest hydrogen and carbon dioxide productivities. However, following 50 h of aging, the catalyst deactivated due to the formation of a high amount of carbonaceous products detected by differential scanning calorimetry/thermogravimetry.
