Exergoenvironmental analysis of hydrogen production through glycerol steam reforming
(2021-01-01)
The increase in biodiesel production is leading to a scenario in which more glycerol, which is a by-product of this biofuel production, is generated each day. Among the many potential applications for this substance, steam ...
Production of hydrogen via steam reforming of biofuels on Ni/CeO(2)-Al(2)O(3) catalysts promoted by noble metals
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The catalytic activity of Ni/CeO(2)-Al(2)O(3) catalysts modified with noble metals (Pt, Ir, Pd and Ru) was investigated for the steam reform of ethanol and glycerol. The catalysts were characterized by the following ...
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 ...
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 ...
Glycerol steam reforming over Ni/Al2O3 catalysts, modified with Mg(II). Effect of Mg (II) content
(Elsevier Science, 2013-04-03)
Ni based catalysts supported over γ-Al2O3, previously modified with increasing contents of Mg(II), were employed for the steam reforming of glycerol. The aim of the present study is to analyze the effect of the content of ...
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 ...
Single stage H2 production, purification and heat supply by means of sorption-enhanced steam reforming of glycerol. A thermodynamic analysis
(Pergamon-Elsevier Science Ltd, 2015-09)
The effect of CO2 removal with CaO in the production and purification of fuel cell-grade H2 by glycerol steam reforming is studied from a thermodynamic point of view. Results obtained with the non-stoichiometric method ...
