Chemical Recuperation of Low-Grade Exhaust Heat by Steam Reforming of Dimethyl Ether
For the new process of effective utilization of energy, chemical recuperation of low-grade exhaust heat by steam reforming of dimethyl ether (DME) was proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O + 122[kJ/mol] → 6H2 + 2CO2. If this reaction could be proceed by exhaust heat below 573 [K], those exhaust heat which is wasted to ambient would be recuperated as the fuel...
متن کاملCatalytic consequences of acid strength in the conversion of methanol to dimethyl ether
0021-9517/$ see front matter 2010 Elsevier Inc. A doi:10.1016/j.jcat.2010.11.017 ⇑ Corresponding author. E-mail addresses: [email protected] (M. Neuro Iglesia). The effects of acid identity on CH3OH dehydration are examined here using density functional theory (DFT) estimates of acid strength (as deprotonation energies, DPE) and reaction energies, combined with rate data on Keggin polyoxometala...
متن کاملBifunctional pathways mediated by Pt clusters and Al2O3 in the catalytic combustion of dimethyl ether.
Mixtures of Pt clusters dispersed on gamma-Al(2)O(3) and additional gamma-Al(2)O(3) led to much higher DME combustion turnover rates than on the individual components or on Pt clusters supported on non-acidic oxides.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولImproved Stability of Pd/Al2O3 Prepared from Palladium Nanoparticles Protected with Carbosilane Dendrons in the Dimethyl Ether Steam Reforming Reaction
The dimethyl ether steam reforming reaction to generate hydrogen was tested over 1 wt % Pd/Al2O3 catalysts prepared from different precursors. The conventional catalyst prepared by incipient wetness impregnation from palladium nitrate underwent strong deactivation under reforming conditions at 823 K because of metal sintering and carbon deposition. The same occurred over the catalyst prepared f...
