| Hydrogen is generally considered as a clean and high efficient energy carrier that can be employed for power generation through fuel cell units, with innocuous water as the only by-product, to decrease the release of pollutants into the atmosphere. Today, there is a developing interest for hydrogen generation from renewable sources such as bio-oil, biogas, bio-ethanol or bio-butanol etc. Among the different renewable feedstock options, ethanol has been viewed as an appealing feedstock because of its relatively high hydrogen content, accessibility, nontoxicity, ease of handling and safety. The present thermodynamic analysis is aimed to explore autothermal conditions at equilibrium for a high H2-syngas production under the combined ethanol steam reforming (SRE), chemical looping partial oxidation (CLPOX) and CO2 solid absorption reaction system. SRE studied conditions were H2O/C2H6O = 3-6 molar ratio, CLPOX employed NiO or CuO as metal oxide (MeO) oxygen carriers from MeO/C2H6O = 0.05-1.5 molar ratio, while 2 kmols of CaO were used for CO2 capture in a T range of 100-900 °C at 1 atm. NiO most favorable adiabatic conditions (T ≥ 500 °C and C ≤ 0.1 kmols) were: H2O/C2H6O = 3 and NiO/C2H6O = 0.05- 0.5. While, for CuO was at H2O/C2H6O = 4, CuO/C2H6O = 0.5 and Tadiab = 529 °C. These favorable reaction conditions are the product of the combination of the exothermic carbonation reaction and its influence over the thermodynamic equilibrium over the POX and SRE endothermic reactions. | |
