Dimethyl ether (DME) as a potential chemical storage of renewable energy was studied for decomposition and steam reforming (DME SR) to produce hydrogen-rich streams over V-Ni/Al2O3 catalysts. The extent of DME decomposition, DME hydrolysis, and subsequent methanol steam reforming was examined during this study, focusing on the redox and acid/base p...

The acetalization of glycerol with acetone represents a strategy for its valorization into solketal as a fuel additive component. Thus, acid carbon-based structured catalyst (SO3H-C) has been prepared, characterized and tested in this reaction. The structured catalyst (L = 5 cm, d = 1 cm) showed a high surface density of acidic sites (2.9 mmol H+ g...

A new multimetallic RhCeNi/Al2O3 catalyst structured in cylindrical pellet with an atomic ratio Ce/Ni=0.55 and minimal Rh content was developed and tested in ethanol steam reforming (ESR) at laboratory and semi-industrial pilot plant scales. A beneficial interaction for the major components, Ce-Ni, is noticed. Ce is mostly present as Ce4+ and Ce+3...

Dimethyl ether steam reforming (DME-SR) for hydrogen production has been studied over VNi/Al2O3 catalysts as part of an investigation aimed at the development of effective technology based on second generation of biofuels. Methanol steam reforming (MeOH-SR) was investigated as a step of the DME-SR process. High activity in the MeOH-SR was observed...

Steam reforming of two representative components in the aqueous fraction of bio-oil, acetone and ethanol, was investigated over nickel based supported catalysts (Ni/Al2O3). The effect of Rh incorporation (Ni-Rh/Al2O3) and the properties of different γ-Al2O3 used as support was tested. Hydrogen-rich gas is produced at temperatures higher than 673K i...
