“…Therefore a balance should be sought, being that a value of 9 is proposed by Chen et al [42] and Silva et al [43] as the most favorable for hydrogen production. In terms of temperature, a more noticeable effect is observed.…”

“…In this case coke formation is only completely avoided at WGFRs above 3 (again for temperatures above 500 K). In another work, Silva et al [43] concluded that even using a WGFR as low as 1.5, it would be possible to work at temperatures below 885 K (1 atm) without any carbon formation. Furthermore, in order to eliminate the possibility of carbon formation in all the temperature range (500-1400 K) under atmospheric pressure, WGFRs higher than 2 would have to be used.…”

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.

Summary:This review paper examines the use of steam reforming to convert bio-liquids like ethanol, glycerol, butanol, vegetable oil, bio-oils and biodiesel into hydrogen gas. The focus of the research was to investigate the research being undertaken in terms of catalyst developments for the steam reforming of the above mentioned feedstock, and to determine the perspective opportunities in this area. Hydrogen production by steam reforming of biooil, ethanol, and pure glycerol has been widely investigated; several thermodynamic and catalytic investigations are available restricting new investigations. In contrast, hydrogen production from waste streams, vegetable oil, biodiesel and butanol is very recent and has room for further developments.
