The effects of alkali addition (eg Li, Na, K) on the behavior of Ni/MgO catalyst in the bio-
ethanol steam reforming have been investigated. Li and Na promote the NiO reduction but …

The syngas redox (SGR) process to produce hydrogen from coal derived syngas is
described. The process involves reduction of a metal oxide to metallic form with syngas and …

The kinetics of hematite (Fe2O3) to wüstite (FeO) reduction has been investigated. Kinetic
parameters have been estimated based on the thermogravimetric data. The Avrami–Erofe'ev …

Interest in hydrogen as a possible energy vector is powered by the depletion of fossil fuel
feedstocks as well as concerns over global warming, which brings new environmental …

Experimental results performed with a fluidized-bed reactor supported the feasibility of the
three processes including direct reduction of iron oxide by char, H 2 production by the …

Hydrogen is a type of clean energy which has the potential to replace the fossil energy for
transportation, domestic and industrial applications. To expand the hydrogen production …

The main objective in doing the present study is to investigate hydrogen production from
biomass via pyrolysis and gasification. Hydrogen is currently derived from nonrenewable …

The chemical-looping hydrogen generation (CLH) system consists of reduction of metal
oxide and water decomposition by oxidizing reduced metal oxide. In the present study, water …

M-modified ferrospinels with the formula M0. 6Fe2. 4Oy (M= Co, Mn or Co/Mn) were
employed as ionic oxygen and electron carrier materials for an alternative sustainable route …

The use of several commercial iron ores usually employed as pigments, to store and supply
pure hydrogen by means of the steam-iron process has been proposed and analyzed. The …
