“…In this regard, production of a hydrogen rich stream by steam reforming (SR) of hydrocarbons or oxygen containing organic compounds has been investigated vastly [2,3]. Methane, methanol (MET), ethanol, acetic acid, and ethylene glycol (EG) are among the fuels most used as the source of hydrogen in steam reforming processes [2][3][4][5][6][7][8][9][10]. Apart from the prevalent fuels, the use of larger molecules such as dimethoxymethane (DMM) and trimethoxymethane (TMM) have attracted attention recently for production of hydrogen-rich gas via SR [11][12][13] or direct oxidation in low temperature fuel cells [13][14][15].…”

For the first time, 2-methoxyethanol (C3H8O2) was used for producing pure hydrogen in a catalytic membrane reactor (CMR) via steam reforming (SR). The SR experiments were performed at 923 K and 1–10 bar using a mixture of 2-methoxyethanol (MEX) and water at S/C ratio of 3. Moreover, SR experiments were performed under the same operating conditions using ethylene glycol (EG), methanol (MET), and a mixture of EG + MET, keeping a constant carbon molar flow rate into the CMR to study the reaction pathway through which 2-methoxyethanol is converted to SR products (CH4, CO, CO2, and H2). Hydrogen recovery values of up to 90% and pure hydrogen yields of 0.5 and 0.63 at 10 bar were reached in the case of the steam reforming of MEX and EG + MET, respectively. An outstanding value of 4 mol of pure hydrogen per mol of MEX was obtained at 10 bar. The presence of methanol promoted the SR of EG. The experimental results showed that 2-methoxyethanol is a promising source for producing hydrogen, especially in a CMR where a better efficiency (complete fuel conversion and high hydrogen yield) is reached.Peer ReviewedPostprint (author's final draft

“…6) and methane decomposition (Eq. 7), are also responsible for coke formation and reduced hydrogen selectivities, contributing to the consequent catalysts deactivation [19,20]. The design of a proper catalytic formulation is a critical challenge to maximize hydrogen production and limit activity losses [21].…”

This work focuses on the support effect on the performances of Co-based catalysts for the acetic acid steam reforming. SBA-15, a well ordered hexagonal mesoporous silica structure, and CeO2 have been selected as the supports, with the impact of chromium addition also being investigated. Better acetic acid steam reforming performances have been recorded for CeO2 compared to SBA-15 supported catalysts and, in particular, the 7Co/CeO2 catalyst showed the highest values of acetic acid conversions with enhanced H2 yields below 480°C, in comparison to the other investigated catalytic formulations. In addition, more pronounced coke depositions and acetone concentrations have been obtained with CeO2 supported catalysts, due to the tendency of ceria to catalyse the ketonization reaction. Chromium addition to Co/SBA-15 catalysts led to an enhancement in the activity towards acetic acid steam reforming, while on CeO2 supported catalysts no improvement in the catalysts activity was observed; however, on both SBA-15 and CeO2 supported catalysts, Cr addition reduced the amount of coke deposited on the catalysts surface.
