Sorption enhanced steam reforming of ethanol on hydrotalcite-like compounds impregnated with active copper.

Sorption enhanced steam reforming of ethanol on CuMgAl hybrid materials was studied. A new method of preparation was employed to the ensemble of catalyst and adsorbent for reaction enhancement. These materials were analyzed on their thermal stability and capacity to uptake carbon dioxide for enhanced hydrogen production process. The effects of material nature and operating conditions on the course of reaction were studied. Hydrogen was generated in the temperature range between 473 K and 873 K. The CuMgAl materials show good stability during the reaction process due to the unique layered double hydroxide structure. The hydrogen production through SRE was enhanced by carbon dioxide sorption in the initial transient period, and high purity hydrogen over 90 mol% was obtained. [ABSTRACT FROM AUTHOR]
