“…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). Gong and co-workers [84] verified that the synergetic effect caused by the partial substitution of La by Ca in the perovskite structure leads to enhanced metal dispersion and stronger metal-support interaction.…”

“…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.

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.

“…However, glycerol can be further used for producing H 2 via steam reforming, partial oxidation and pyrolysis reactions [93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,…”

Glycerol Production and Transformation: A Critical Review with Particular Emphasis on Glycerol Reforming Reaction for Producing Hydrogen in Conventional and Membrane Reactors

et al. 2017

Glycerol represents an emerging renewable bio-derived feedstock, which could be used as a source for producing hydrogen through steam reforming reaction. In this review, the state-of-the-art about glycerol production processes is reviewed, with particular focus on glycerol reforming reactions and on the main catalysts under development. Furthermore, the use of membrane catalytic reactors instead of conventional reactors for steam reforming is discussed. Finally, the review describes the utilization of the Pd-based membrane reactor technology, pointing out the ability of these alternative fuel processors to simultaneously extract high purity hydrogen and enhance the whole performances of the reaction system in terms of glycerol conversion and hydrogen yield.
