“…Besides ethanol other value-added chemicals can be produced from renewable feedstocks [25]. Simultaneouly efficient processes were developed for the conversion of bagasse to methane [26] or hydrogen [27][28][29][30], or C 5 and C 6 sugars [31,32]. A new innovation showed that sweet sorgum fiber could be used to reinforce fly ash-based geopolymer [33] which is the latest potential use.…”

“…It is important to emphasize that utilization of sweet sorghum turned to the production of other chemical compounds from the carbohydrate content of the raw juice such as lactic acid [34][35][36][37], butanol [38], hydrogen [28,39,40], acetone [41], lipids [42] gained more importance. Among the platform molecules levulinic acid could play a key role in the chain [43], since it is the raw material of a proposed platform chemical (gamma-valerolactone) that can be obtained by its selective hydrogenation [44][45][46][47][48].…”

The development of sweet sorghum syrup producing technology for the juice of cultivar Sucrosorgho 506 was completed. The applicability of different existing syrup production technologies including sugar beet-based sugar production technology, and sugar cane processing technology was also tested. The new chemical-free syrup production technology was realized at laboratory-scale and large laboratory-scale. The proposed technology offers a chemical free separation and concentration of carbohydrates, and consists of centrifugal separation; ultrafiltration extended with an approved sterilization followed by nanofiltration to separate carbohydrates and inorganics, and finally a vacuum evaporation to reach syrup state. By using this technology the initial glucose:fructose:sucrose ratio could be preserved in the syrup, therefore not limiting its further use. The possible food application was established by sensory analysis. It was revealed that the syrup produced via the developed process obtained the most attractive character that enables the opportunity to use as natural sweetener.

“…Lignocellulosic feedstocks consist mainly of glucose and xylose and thus microbial strains that can effectively degrade glucose and xylose are important for development of renewable H 2 production processes [18]. Direct conversion of lignocellulosic biomass to H 2 needs pretreatment to hydrolyze the incorporated heterogeneous and crystalline structure [19,20]. The lignocellulosic biomass hence presents an attractive, low-cost feed stock for H 2 production.…”

Biohydrogen Production from Lignocellulosic Biomass: Technology and Sustainability

et al. 2015

View full text Add to dashboard Cite

Among the various renewable energy sources, biohydrogen is gaining a lot of traction as it has very high efficiency of conversion to usable power with less pollutant generation. The various technologies available for the production of biohydrogen from lignocellulosic biomass such as direct biophotolysis, indirect biophotolysis, photo, and dark fermentations have some drawbacks (e.g., low yield and slower production rate, etc.), which limits their practical application. Among these, metabolic engineering is presently the most promising for the production of biohydrogen as it overcomes most of the limitations in other technologies. Microbial electrolysis is another recent technology that is progressing very rapidly. However, it is the dark fermentation approach, followed by photo fermentation, which seem closer to commercialization. Biohydrogen production from lignocellulosic biomass is particularly suitable for relatively small and decentralized systems and it can be considered as an important sustainable and renewable energy source. The comprehensive life cycle assessment (LCA) of biohydrogen production from lignocellulosic biomass and its comparison with other biofuels can be a tool for policy decisions. In this paper, we discuss the various possible approaches for producing biohydrogen from lignocellulosic biomass which is an globally available abundant resource. The main technological challenges are discussed in detail, followed by potential solutions.

“…In wastewater from the food industry, it is possible to find a high concentration of glucose. Glucose can be converted into hydrogen by several reactions, such as steam reforming [4,5], wet oxidation of glucose [6], oxidative glucose reforming [7], pyrolysis [8], biophotolysis [9,10], dark fermentation [11], electrolysis [12] and photocatalysis [13,14]. Hydrogen has been identified as an ideal energy carrier for sustainable energy development [15][16][17][18] and it can be used in a fuel cell to generate electricity with high efficiency.…”

-In this work, the simultaneous production of CH 4 and H 2 from photocatalytic reforming of glucose aqueous solution on Pd-TiO 2 catalysts under UV light irradiation by Light-Emitting Diodes (LED) was investigated. The Pd-TiO 2 catalysts were prepared by the photodeposition method. The Pd content was in the range 0.5-2 wt% and a photodeposition time in the range 15-120 min was used. Pd-TiO 2 powders were extensively characterized by X-Ray Diffraction (XRD), S BET , X-Ray Fluorescence spectrometry (XRF), UV-Vis Diffuse Reflectance Spectra (UV-Vis DRS), TEM and X-Ray Photoelectron Spectroscopy (XPS). It was found that the lower Pd loading (0.5 wt%) and 120 min of photodeposition time allowed us to obtain homogeneously distributed metal nanoparticles of small size; it was also observed that the increase in the metal loading and deposition time led to increasing the Pd 0 species effectively deposited on the sulfated TiO 2 surface. Particle size and the oxidation state of the palladium were the main factors influencing the photocatalytic activity and selectivity. The presence of palladium on the sulfated titania surface enhanced the H 2 and CH 4 production. In fact, on the catalyst with 0.5 wt% Pd loading and 120 min of photodeposition time, H 2 production of about 26 lmol was obtained after 3 h of irradiation time, higher than that obtained with titania without Pd (about 8.5 lmol). The same result was obtained for the methane production. The initial pH of the solution strongly affected the selectivity of the system. In more acidic conditions, the production of H 2 was enhanced, while the CH 4 formation was higher under alkaline conditions.Résumé -Production simultanée de CH 4 et H 2 par réformage photocatalytique d'une solution aqueuse de glucose sur un catalyseur Pd-TiO 2 sulfaté -Dans cette recherche, la production simultanée de CH 4 et H 2 par le reformage photocatalytique de glucose sur les catalyseurs Pd-TiO 2 sous irradiation de lumière UV réalisée par des diodes électroluminescentes (LED) a été étudiée.
