“…Products from zeolite upgrading (HZSM-5) of model biomass compounds including propanol, butanol, and acetone adapted from Gayubo et al 228,229 dibenzyl ether, glucose, xylose, and sucrose, has been carried out with Ni 240 and noble metal-based catalysts. 241,242 Acetic acid caused coking problems on the Ni catalyst surface, while glucose, xylose, and sucrose thermally decomposed prior to the catalyst bed. 240 The sugars once volatilized did not cause coking problems on the catalyst surface but decomposed in tubing prior to the catalyst bed.…”

“…The use of ZrO2 as a catalyst modifier has also been reported as an alternative promoter [18,65,67,68], despite the fact that ZrO2 alone is not very active for steam reforming [71]. Iriondo et al [67] observed that the addition of zirconia promoter to alumina not only enhanced the performance of the non-promoted catalyst but also presented better GSR performance than the ceria-promoted catalyst.…”

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.

“…Acetic acid, one of major constituents of pyrolysis oil that can reach up to 12 wt% of biomass oils [9], has become the focus of research in steam reforming [10], [11] [12] [13] [1] [14,15] [16]. Vagia and Lemonidou [7] reported that the yield of H 2 approached 80% of the maximum when steam reforming acetic acid at 750 °C, producing mainly H 2 , CO 2 and CO, and small amount of CH 4 .…”

The benefits of CO 2 sorption enhanced steam reforming using calcined dolomite were demonstrated for the production of hydrogen from highly oxygenated pyrolysis oils of the agricultural waste palm empty fruit bunches (PEFB) and pine wood. At 1 atm in a down-flow packed bed reactor at 600 °C, the best molar steam to carbon ratios were between 2 and 3 using a Ni catalyst. After incorporating steam-activated calcined dolomite as the CO 2 sorbent in the reactor bed, the H 2 yield from the moisture free PEFB oil increased from 9.5 to 10.4 wt% while that of the pine oil increased from 9.9 to 13.9 wt%. The hydrogen purity also rose from 68 to 96% and from 54 to 87 % for the PEFB and pine oils respectively, demonstrating very substantial sorption enhancement effects.
