Title: Steam reforming of olive oil mill wastewater with in situ hydrogen and carbon dioxide separation Thermodynamic analysis
Issue Date: 2017
Abstract: A thermodynamic analysis of the steam reforming reaction of olive oil mill wastewater (OMW) with in situ carbon dioxide (CO2) and hydrogen (H2) simultaneous removal was performed. The idea behind is the integration of the reformer with a H2-selective membrane and a CO2-sorbent in a hybrid multifunctional reactor. The simulations were performed at different temperatures (300500 °C), pressures (111 bar), removal fractions of H2 (00.8), removal fractions of CO2 (00.99) and also for different water contents in the feed (2092 wt.%). The results were compared in terms of performance reached for the different reactor configurations: traditional reactor (TR), membrane reactor (MR) with H2 separation, sorption-enhanced reactor (SER) with CO2 capture and sorption-enhanced membrane reactor (SEMR). For the SEMR, the optimum operation conditions were determined. An H2 yield very close to the stoichiometric value of 13.54 was obtained at 1 bar, 500 °C, water content in the feed of 6092 wt.% (steam-to-carbon feed ratio, SCFR = 2.116.0), fCO2 = 0.99 and fH2 = 0.80. The H2 yield obtained in such optimum conditions corresponds to an enhancement of 141% comparatively to the TR. Moreover, under these operation conditions there is no significant production of CO2, CO, CH4 and coke. © 2017 Elsevier Ltd
