Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

Hydrogen production by reforming of bio-alcohols

“…Ethanol dehydrogenation to CH 3 CHO and ethanol decomposition to CH 4 and CO were the primary reactions over CeO 2 -supported Pt-Co, Ir, and Pt-Ni catalysts; however, they were significantly active and selective for H 2 production by ESR at a high temperature (Palma, Castaldo, Ciambelli, & Iaquaniello, 2013, 2012a, 2012bPalma, Palo, Castaldo, Ciambelli, Iaquaniello, 2012). Intermediate compounds such as CH 3 CHO and CH 3 COCH 3 were completely converted into H 2 , CO, and CO 2 as the result of the major reactions of CH 4 SR and reverse WGS.…”

Experimental and simulation studies of the production of renewable hydrogen through ethanol steam reforming in a large-scale catalytic membrane reactor

“…The kinetic properties of ESR for different catalysts have been studied throughout the literature and different mechanisms have been proposed [15,[28][29][30][31][32][33][34]. Nonetheless, it is considered that the reactions shown in Eqs.…”

“…15,48,65 In contrast, Ni-based catalysts are not stable for more than 10 h of reaction time as they incur coke deposition. [61][62][63] Furthermore, the addition of new metals or alkaline elements is found to improve the properties of the catalyst and make it more stable. 48,62,66 …”

“…Barroso et al 61 reported that that Ni/MgAl catalyst has an initial ethanol conversion of 100%, which decreases to 50% after 11 h of reaction at 650 °C. Palma et al 62 studied the Pt-Ni/CeO 2 catalyst at 450 °C. Although, there are no appreciable changes in the distribution of products after 5 h of reaction, there is a significant drop in the pressure, which indicates coking of the catalyst.…”
