“…There was also no significant change in the distribution of mesoporous pore diameter with only a slight decrease of intensity after Ni loading comparing with the fresh SBA-15. This demonstrated that the impregnation, drying and calcination steps during the preparation of the catalysts had no significant effect on the micropore and mesoporous distribution of HZSM-5 and SBA-15 [7,[12][13][14]. 9° were attributed to the ZSM-5 zeolite crystal structure [15,16].…”

Aromatics and cyclic-hydrocarbons are the significant components of jet fuel with high energy-density. However, conventional technologies for bio-fuel production cannot produce these products without further aromatization and isomerization. In this work, renewable liquid fuel with high content of aromatics and cyclic-hydrocarbons was obtained through aqueous catalytic conversion of biomass sorbitol over Ni-HZSM-5/SBA-15 catalyst. Texture characteristics of the catalyst were determined by physisorption of N2, which indicated its bimodal pore structures were microporous (HZSM-5, pore width: 0.56 nm) and mesoporous (SBA-15, pore width: 8 nm). The surface acidity included weak and strong acid sites, predominantly Lewis type, and was further confirmed by the NH3-TPD and Py-IR analysis. The catalytic performances were tested in a fixed-bed reactor under the conditions of 593 K, WHSV of 0.75 h

“…For example, bimetallic platinum-rhenium/C catalyst agents with Pt/Re atomic ratios lower than 1 yield through GSR a fivefold increase in syngas yield, comparatively with monometallic Pt/C and Pt-Re with a Pt/Re molar ratio higher than 10. A main effect should be the attenuation of the chemical bond between CO and surface, facilitating the regeneration of the catalytic sites [144].…”

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.

“…From many catalytic systems used for glycerol steam reforming, those based on metals such as Ru [18,25,26], Rh [17,26], Ir [26][27][28], Pd [26,29,30], Pt [17,26,[31][32][33][34], and Co [27] can be mentioned. Different supports were also used including CeO 2 [25,27,35,36], Al 2 O 3 [24][25][26]37], MgO [35], TiO 2 [35] and ZrO 2 [36].…”

This paper presents reports on the glycerol steam reforming reaction. The studies were performed over four nickel catalysts with different metal loading (up to 10 wt%) supported on calcium deficient hydroxyapatite (DHAp). The support was synthetized by the microwave assisted hydrothermal method. The steam reforming reaction was performed under atmospheric pressure in the 650-800°C temperature range using 10 mg of catalyst sample and a glycerol/water mixture with S/C = 3. All catalysts were well characterized by physicochemical methods (XRD, XRF, TPR, HRTEM). The catalytic tests results were presented by means of glycerol conversion, hydrogen and carbon containing gases selectivity. The most promising results were obtained for catalyst with moderate Ni content (*7.5 wt%), which proved to be stable during a few hours on-stream and provided glycerol conversion at least 94% at reaction temperature above 750°C.
