Nickel catalysts applied in steam reforming of glycerol for hydrogen production
(Elsevier Science, 2009-07)
In order to study catalysts to obtain hydrogen by steam reforming of glycerol, nickel catalysts supported on commercial α-Al2O3 and α-Al2O3 modified by addition of ZrO2 and CeO2 were prepared and characterized. Results ...
Economic assessment of hydrogen and electricity cogeneration through steam reforming-SOFC system in the Brazilian biodiesel industry
(2021-01-10)
The increase of environmental concern has led to an increase in biodiesel production, which also produces high amounts of glycerol. This growing production is causing glycerol prices to plummet while constant efforts are ...
Hydrogen production by crude glycerol steam reforming over Ni-La-Ti mixed oxide catalysts,
(Pergamon-Elsevier Science Ltd, 2017-12)
The production of H2-rich gaseous mixtures from steam reforming of crude glycerol was investigated on ternary Ni-Le-Ti catalysts. Ni-La-Ti mixed oxides containing 15 wt% of Ni and a La/Ti atomic ratio of 1 were prepared ...
Temperature charts of Hevea brasiliensis during log steaming and its effect on the board cracks
(Springer, 2014-01-01)
The temperatures of Hevea brasiliensis logs during the steaming process were determined and correlated with the cracks of the boards. Thermocouples were inserted at the center of the logs, and the temperatures were recorded ...
Hydrogen production by biogas steam reforming: A technical, economic and ecological analysis
(2013-08-28)
Fuel cells are electrochemical energy conversion devices that convert fuel and oxidant electrochemically into electrical energy, water and heat. Compared to traditional electricity generation technologies that use combustion ...

Steam reforming of glycerol: Hydrogen production optimization
(Pergamon-Elsevier Science Ltd, 2015-04)
The glycerol steam reforming reaction was studied using Pt-based catalysts in order to selectively produce hydrogen. The global steam reforming reaction is the combination of two consecutive steps: i) glycerol decomposition ...
Ethanol steam reforming for production of hydrogen on magnesium aluminate-supported cobalt catalysts promoted by noble metals
(ELSEVIER SCIENCE BV, 2009)
The performance of noble metal (Pt, Ru, Ir)-promoted Co/MgAl(2)O(4) catalysts for the steam reforming of ethanol was investigated. The catalysts were characterized by energy-dispersive X-ray spectroscopy, Xray diffraction, ...
