Behavior of a CuFe2O4/γ-Al2O3 Catalyst for the Steam Reforming of Dimethyl Ether in Reaction-Regeneration Cycles

“…Accordingly, a fraction of the reactor outlet stream was continuously diluted and impelled by the auxiliary gas (a He stream of 30 cm 3 min −1 ) to the gas chromatograph through a thermostated line (at 150 °C) to avoid the condensation of liquid compounds. The gas chromatograph is provided with four modules for the analysis of the following: (1) The experiments were conducted in reaction-regeneration cycles in order to analyze the recovery of the reaction indices in the successive reaction runs. Prior to each reforming reaction run, the catalyst was reduced "in situ", using 10% H 2 in He at 300 °C for 2 h with a total flow rate of 100 cm 3 min −1 .…”

“…H 2 appears to be a clean raw material and energy carrier that can be used in transport and stationary energy generation. 1,2 H 2 can be used directly or through a hydrogenated intermediate (H 2 carrier) that can be transformed in situ to H 2 by reforming for its use in hydrogen fuel cells. 3,4 Among the compounds available as H 2 vectors in fuel cells, dimethyl ether (DME) has received considerable attention.…”

“…The increasing global demand of energy accelerates the depletion of fossil fuels, thus boosting the search of alternative energy sources. H 2 appears to be a clean raw material and energy carrier that can be used in transport and stationary energy generation. , H 2 can be used directly or through a hydrogenated intermediate (H 2 carrier) that can be transformed in situ to H 2 by reforming for its use in hydrogen fuel cells. , Among the compounds available as H 2 vectors in fuel cells, dimethyl ether (DME) has received considerable attention. DME has a high hydrogen-to-carbon ratio and high energetic density; it also can be stored and handled as liquified petroleum gas (LPG) and therefore can be more readily used in fuel cells.…”

Evaluation of on-site hydrogen generation via steam reforming of biodiesel: Process optimization and heat integration

“…Today, hydrogen is predominantly produced by steam reforming of natural gas in large-scale, central production plants. However, with an increasing share of fuel cell vehicles (FCVs) in the market, central hydrogen production will suffer from additional costs associated with the distribution of gaseous-phase hydrogen by trailer over long distances (1). In contrast, distributed hydrogen generation (DHG) at fueling stations offers the advantage of using readily available liquid fuels such as diesel and biodiesel with high energy densities and existing infrastructure.…”
