Catalyst Design for Reforming of Oxygenates

Renewable H2 from Glycerol Steam Reforming: Effect of La2O3 and CeO2 Addition to Pt/Al2O3 catalysts.

“…[15][16][17] Several methods have been proposed for the H 2 production from renewables: biomass reforming and water electrolysis using solar, wind, or hydroelectric power. [18] Recently biodiesel has become one of the most promising biofuels, [19][20][21][22] although its relatively high production costs are a limitation to its worldwide acceptance. The recovery of byproducts (mainly glycerol) from biodiesel production and their use as new feedstocks in biorefineries [23,24] can strongly contribute to bringing down the overall production costs of biodiesel.…”

Catalytic partial oxidation of a biodiesel surrogate over molybdenum dioxide

“…This study will provide new insights for reforming complex oxygenated fuels, in which coke formation might become a considerable issue because of the inherit tendency of biodiesel to form carbonaceous species due to their long hydrocarbon chain and thermal instability at high temperatures [11,21]. Thus, in a long-term run, nickelbased catalysts cannot be considered as a suitable option owing to their well-known propensity to form graphitic carbon, whereas the use of noble metal (e.g., Ru, Rh, Pd, Pt or Ir) catalysts is not economically feasible.…”

“…Furthermore, as with other liquid fuels, biodiesel could be employed in a fuel cell system where it is pre-fed into an external reformer to produce synthesis gas. Nevertheless, at this time, the state of the art for the catalytic partial oxidation (CPO) of oxygenated molecules for the production of synthesis gas relies mainly on light alcohols such as methanol or ethanol [11].…”

“…In this regard, the use of renewable resources will contribute to reducing polluting gases, decreasing the dependence of energy imports, and promoting local and regional economies [10][11][12]. Biodiesel -a non-toxic and biodegradable mixture of long chain fatty acid methyl esters made by transesterification of vegetable oils and animal fats -represents a prospective liquid transportation fuel with high potential to replace diesel and Jet-A fuel in the future with 60% less net-life cycle carbon dioxide emissions [13][14][15].…”

Advances and Recent Trends in Heterogeneous Photo(Electro)-Catalysis for Solar Fuels and Chemicals

“…In addition, although it has been a growing area of research in the last 20 years, ethanol SR still suffers from catalyst deactivation due to carbon deposition, probably linked to the high temperatures necessary to establish good conversion rates [ 30 , 31 ]. Nevertheless, the scope for bio-hydrogen resources now encompasses a range of oxygenates and polyols, e.g., glycerol (a waste product from bio-diesel synthesis [ 32 , 33 ]), in which coking can be minimized via aqueous-phase-reforming (APR) under mild conditions [ 34 ].…”
