Renewable biohydrogen production from lignocellulosic biomass using fermentation and integration of systems with other energy generation technologies

Biohydrogen is a clean and renewable source of energy. It can be produced by using technologies such as thermo-chemical, electrolysis, photoelectrochemical and biological, etc. Among these technologies, the biological method (dark fermentation) is considered more sustainable and ecofriendly. Dark fermentation involves anaerobic microbes which degrade carbohydrate rich substrate and produce hydrogen. Lignocellulosic biomass is an abundantly available raw material and can be utilized as an economic and renewable substrate for biohydrogen production. Although there are many hurdles, continuous advancements in lignocellulosic biomass pretreatment technology, microbial fermentation (mixed substrate and co-culture fermentation), the involvement of molecular biology techniques, and understanding of various factors (pH, T, addition of nanomaterials) effect on biohydrogen productivity and yield render this technology efficient and capable to meet future energy demands. Further integration of biohydrogen production technology with other products such as bio-alcohol, volatile fatty acids (VFAs), and methane have the potential to improve the efficiency and economics of the overall process. In this article, various methods used for lignocellulosic biomass pretreatment, technologies in trends to produce and improve biohydrogen production, a coproduction of other energy resources, and techno-economic analysis of biohydrogen production from lignocellulosic biomass are reviewed.

Reaction mechanisms and product patterns of Pteris vittata pyrolysis for cleaner energy

The pyrolysis behaviors, kinetics, evolved products, and optimization of aboveground (PA) and below ground (PB) biomass of Pteris vittata were quantified. The pyrolysis performance in response to the elevated heating rate was improved by 21.21 and 16.79 times for PA and PB, respectively. CH4 and CO emissions were produced more from the pyrolysis of PB than PA. The increased pyrolysis temperatures of PA and PB led to the three consecutive releases of C=O (alcohol, ketone, acid, and furan), C-O (alcohol, phenol, and ether), and CO2, CH4, H2O, and CO. The formations of NH3 and HCN were more sensitive to the temperature rise with PB than PA. PA produced alcohol/ketone and acids by 1.81 and 1.32 times what PB produced. PB produced furan and carbohydrate/alkene by 1.56 and 2.52 times what PA produced. PA appeared as a more suitable feedstock than PB and showed an optimal pyrolysis behavior at 545 degrees C and 45 degrees C/min. Our findings can provide the basis for characterizing the process and environmental benignity of the hyperaccumulator pyrolysis. (c) 2020 Elsevier Ltd. All rights reserved.

Application of a new reagent for analysis of oxygen presence in a low-carbon steel wire rod

A microstructural analysis was performed to determine the presence of oxygen in a wire rod section of AISI 1008 steel with a surface mechanical failure produced during wire drawing. The failure zone was analyzed by comparison using three different attack reagents: alkaline sodium chromate (ASC), ASC with hydrogen peroxide and amyl alcohol, and a solution of nitric acid in ethyl alcohol. The reagents were applied in samples in the failure zone, showing different types of zones in regions with internal and superficial defects such as carbides, pores, cracks, deformation, and detachment zones, indicating the possible presence of oxygen. The areas identified were observed by means of an optical microscope and were correlated with the content of elements that were present in the region using a scanning electron microscope and a scattered X-ray energy spectrometer, which determined that the areas identified by chromate sodium correspond to regions with a high concentration of oxygen and slag-forming elements such as silicon, aluminum, and iron; this is associated with the presence of oxygen in the oxide form. It was also observed that the ASC and the modified ASC solution with hydrogen peroxide and amyl alcohol could identify areas with a high presence of oxides, while the nitric acid solution only identified the steel microstructure. The modified ASC solution is an alternative to identify the presence of chemical variants of oxygen because the conventional formulation is unstable and has a too short shelf life, and therefore, its application must be carried out at the time of preparation.

Persulfate activation by ZIF-67-derived cobalt/nitrogen-doped carbon composites: Kinetics and mechanisms dependent on persulfate precursor

Whereas previous studies that explored the application of metal-carbon composites as persulfate activators have focused on synergistic performance improvements, the potential advantages or features that can be acquired by integrating metal and carbon constituents that differ in terms of reactivity toward persulfate precursors and their preferred activation routes have been overlooked. With ZIF-67-derived cobalt/N-doped carbon composites (Co@N-C) as the model metal-carbon composite, this study takes a look into a switch in the primary degradative pathway depending on the persulfate precursor used and investigates this kind of composite fabrication as a strategy to overcome the drawbacks of single-component activators. In Co@N-C, Co embedded in the carbon matrix caused radical-induced oxidation in the presence of peroxymonosulfate (PMS) whereas peroxydisulfate (PDS) activation using a carbon framework involved mediated electron transfer. The different nature of the dominant oxidant was confirmed by investigating the quenching effects of alcohols, bromate formation yield, substrate-specificity, electron paramagnetic resonance spectral features, current generation upon sequential organic and persulfate injection, and product distribution. The Co and N-doped carbon serving as separate reactive sites allowed Co@N-C to exploit both PMS and PDS so it could outperform benchmark metaland carbon-derived materials. Electrochemical measurements linked with X-ray spectroscopic analysis implied that a moderate pyrolysis temperature optimized the Co@N-C activity due to high fractions of graphitic N and Co-N species. Density functional theory calculations reveal that the peroxide bond of PMS is more susceptible to elongation over Co@N-C, thus it is preferentially dissociated to yield sulfate radicals.

Effective degradation of tetracycline via polyvinyl alcohol /Bi2WO6 hybrid hydrogel with easy separation

Developing inexpensive and stable photocatalysts with easy separation for the degradation of antibiotics is highly needed. In this study, a three-dimensional poly(vinyl alcohol) (PVA)/Bi2WO6 (BWO) (PVA/BWO) hybrid hydrogel photocatalyst with easy separation was constructed via freeze-thaw process and then was used to remove Tetracycline (TC) from water. The obtained hydrogels were characterized by various techniques. SEM image and EDS mapping show the successful decoration of BWO and the BWO is homogenously distributed on the PVA substrate. Results of the photocatalytic experiment and total organic carbon content (TOC) measurement show that the constructed PVA/BWO hydrogel could degrade TC effectively under visible light irradiation, even after the PVA/BWO hydrogel had been recycled for five times. Results of XRD, SEM and EDS mapping on the fresh and used PVA/BWO hydrogel confirm its relatively good stability in structure. The possible reaction pathways and mechanism of TC degradation were also analyzed. The PVA/BWO hybrid hydrogel with easy separation could be a new alternative with great potential in efficient removal of persistent organic pollutants.
