摘要：

In last years, sorption-enhanced steam reforming of ethanol (SESRE) has become an interesting alternative for the industry, since it offers high H-2 purity with a simpler and smaller system. In this study CaO derived materials were synthesized to improve multicyclic CO2 sorption-desorption stability. A dispersant and inert phase (Ca12Al14O33) was incorporated into CaO structure. The effects of CaO:Ca12Al14O33 ratio on the characteristics of the new absorbents and on their performance in sorption-enhanced steam reforming of ethanol were analyzed. The results obtained indicate that the absorbent 85% CaO - 15% Ca12Al14O33 had significantly improved cyclic reaction stability. Additionally, it was proved that with this adsorbent CO purity on wet basis was lower than 2 %, making it possible to attain in only one reaction stage the CO purity obtained after de WGS reactor.
