“…It has been found that the use of low amounts of Mg(II) promoter leads to higher metal dispersion, thus favoring glycerol conversion into gaseous products, while higher loadings result in lower coke deposition [20]. Other basic promoters such as Mo [66,[79][80][81][82][83] and Ca [66,69,79] have also been reported to enhance the GSR performance of non-promoted catalyst, for the same reasons previously mentioned for basic modifiers. Huang et al [66] observed that the simultaneous presence of Mo-La-Ca inhibits the interaction between nickel and the commercial Ca-containing Linde-type 5A zeolite support, thus resulting in a remarkable stability during GSR (no deactivation during 100 h time-on-stream).…”

The steam reforming of the main biodiesel by-product, glycerol, has been catching up the interest of the scientific community in the last years. The use of glycerol for hydrogen production is an advantageous option not only because glycerol is renewable but also because it's use would lead to the decrease of the price of biodiesel, thus making it more competitive. Consequently, the use of biodiesel at large scale would significantly reduce CO2 emissions comparatively to fossil fuels. Moreover, hydrogen itself is seen as a very attractive clean fuel for transportation purposes.Therefore, the industrialization of the glycerol steam reforming (GSR) process would have a tremendous global environmental impact. In the last years, intensive research regarding GSR thermodynamics, catalysts, reaction mechanisms and kinetics, and innovative reactor configurations (sorption enhanced reactors (SERs) and membrane reactors (MRs)) has been done, aiming for improving the process effectiveness. In this review, the main challenges and strategies adopted for optimization of GSR process are addressed, namely the GSR thermodynamic aspects, the last developments on catalysis and kinetics, as well as the last advances on GSR performed in SERs and MRs.

“…Many catalytic formulations are active for liquid HC reforming. However, very few among the reported catalysts are stable for more than 15 h. Doping agents, such as magnesium and calcium, can improve the resistance of Ni catalysts. A new patent pending catalytic formulation has been proposed and tested with success on commercial diesel SR.…”

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.

“…As aforementioned, ceria shows good characteristics for GSR and has been also suggested as a valid promoter [129,130]. Indeed, ceria shows an aptitude to stabilize the nickel active phase and to promote the reforming of intermediated hydrocarbons with oxygen, contributing thereby for decreasing the coke deposits.…”

Abstract:Glycerol is a by-product of biodiesel obtained from biomass, accounting for 10% of the biodiesel production. In the context of a green economy, aiming for a reduction of the emission of atmospheric greenhouse gases emissions, the demand of biodiesel is expected to increase vastly, in parallel with a side glut supply of glycerol. Given the high cost of biodiesel compared with its fossil congener, upgrading of glycerol into added-value products can represent a secondary income source and turn the production of such alternative fuels economically sustainable in the long term. The glycerol obtained as by-product of biodiesel from biomass is in a crude form and must be purified. Some industrial solutions and applications were therein geared. The survey presented in this work, based on a reviewing of the existing literature, examines three routes for the valuing glycerol into energy carriers and chemicals, namely, carbonation, acylation, and steam reforming to hydrogen. The latter is embodied of great interest and importance, insofar that hydrogen by itself is considered as straighforward clean fuel for transportation uses, due to its high calorific power and to recent advances in fuel cells. We also have focused on the chain value from biomass to energies carriers through these pathways.
