“…Although these values are in agreement with most previous investigations of ATR of glycerol [17,28,54], the thermal and the exergetic efficiencies of the subsequent process are relatively lower than those cited in the literature and similar those for other reformates (methane, propane, ethanol and gasoline). The parametric energetic and exergetic investigations indicate that a WGFR ¼ 9 could lower the performances of the entire glycerol-tohydrogen process and that lowering the WGFR might improve the process performance.…”

International audienceIn this work, various assessment tools were comprehensively applied to investigate hydrogen production via glycerol autothermal reforming. These tools are used to study the chemical reactions, design and simulate the entire hydrogen production process, investigate the energetic and exergetic performances of the processes and perform parametric analyses (using intuitive and design of experiment-based methods). Investigating the chemical reactions of autothermal reforming (ATR) of glycerol reveals that the optimal conditions, based on maximizing the hydrogen production, minimizing the methane and carbon monoxide contents and eliminating coke formation at thermoneutral conditions, can be achieved at a water glycerol feed ratio (WGFR), reforming temperature (T) and oxygen-glycerol feed ratio (OGFR) of 9, 900 K and 0.35, respectively. The energetic study of the resulting process indicates that approximately two-thirds of the energy fed to the process is recovered in the useful product (H-2) and that the remaining incoming process energy is exhausted in the off-gas. The exergetic investigation reveals that the exergetic efficiency of the ATR process is 57% and that 152 kJ are destroyed to generate 1 mol of hydrogen. The process operating conditions recommended by the chemical reaction investigation suffers from low performance because energetic and exergetic efficiencies are comparatively lower than values previously reported in literature for other reformates. The parametric investigation indicates that more accurate conditions are needed to convert glycerol hydrogen. These conditions ensure the lowest consumption of energy to generate a given amount of hydrogen. This paper recommends WGFR = 5.5, T = 900 K and OGFR = 0.96 as the optimum conditions for the entire glycerol-to-hydrogen process. For this configuration, the thermal and exergetic efficiencies are 78.7% and 67.8%, respectively

Although natural gas is the main feedstock for the production of hydrogen and syngas, liquid hydrocarbons and oxygenated compounds are of interest for reasons associated with their local availability and their easiness to be stored and transported. This review focuses on steam, dry, and partial oxidation of liquid feedstock. The vast research work published in these fields does not allow for a full coverage of the entire literature. Instead, the authors present from both scientific and technical stand points the knowledge which seems more promising toward eventual improvements of commercial units and utilization of new catalytic formulations. Since traditional steam reforming is relatively very well covered by other reviews, this review has mainly focused on the relatively recent works on glycerol, a biodiesel production by-product, and the widely available and distributed commercial diesel/biodiesel. New promising catalytic formulations are proposed and are actually under testing for eventual commercial use. Nevertheless these catalysts might be eventually efficient for gaseous (e.g., CH 4 ) hydrocarbons conversion to syngas. Dry and partial oxidation has also been reviewed both globally and in an incremental way. All liquid feedstock tested are reported. Finally, this review tries to bridge the gap between fundamental and factual research in this field. Both are important but the interpretation of the results remains a strong function of each paper's main focus. This review does not pretend that this gap is fully bridged but it has the ambition to help the researchers as well as the practitioners in this area to synthesize the existing knowledge.

“…The oxygen intermediates effectively affected the (OSC) of the promoters, especially CeO2 ZrO2, by replenishing the oxygen vacancies in the ceria containing support, and in turn helping to reduce carbon formation. Kamonsuangkasem et al [80] examined the use of 15 wt% Ni impregnated on 8%CeO2-ZrO2 modified Al2O3 in ATR of yellow glycerol. The best performance of the catalyst was reported over steam/glycerol and oxygen/glycerol molar ratios of 9 and 0.5 at 650 °C, respectively.…”

The use of ceria-zirconia based catalysts in hydrogen production from simple alkanes and oxygenated hydrocarbons for the processes of steam reforming (SR), autothermal reforming ('ATR'), catalytic partial oxidation ('CPO'), and dry reforming ('DR') are reviewed in this paper. Along with preparation methods, the effects of operating conditions like molar steam to carbon ratio, oxygen to carbon ratio, and temperature on the performance of hydrogen production from methane, acetic acid, ethanol, and glycerol were examined. SR and ATR of these feedstocks over ceria-zirconia supports have been widely investigated. In comparison the utilization of these supports in the CPO and DR processes has been investigated mainly for methane as compared to oxygenated hydrocarbons. Ce-rich supports were reported to be effective in hydrogen from SR and ATR of ethanol and glycerol and in SMR in the 'low' temperature range (500-600 °C), whereas zirconium-rich supports exhibited higher catalytic activity in the 'high' temperature range (700-800 °C). In the case of DR, Ce-rich supports were effective at high temperature. The methods of preparation of the supports/catalyst are shown to affect the surface area (catalyst/support), crystallite size of (active metal/support), reducibility and dispersion of the active metal, thus affecting performance of the catalyst.
