What evidence supports that deionised water contains only hydrogen and hydroxide ions?
5 answers
Evidence supporting that deionized water contains only hydrogen and hydroxide ions comes from various studies. X-ray Raman spectroscopy (XRS) and small-angle x-ray scattering (SAXS) analyses of HCl and NaOH solutions reveal that H+ and OH− ions have distinct effects on water structure, with H+ enhancing local hydrogen bonds and OH− inducing tetrahedrality in the overall hydrogen bond network.

What are the key motivations for torrefaction of agricultural residues (or agricultural biomass)?
6 answers
The key motivations for torrefaction of agricultural residues stem from the need to address environmental concerns, enhance biomass fuel properties, and improve the efficiency of biomass utilization for energy production. Firstly, the process of torrefaction significantly improves the thermal properties of biomass, such as empty fruit bunch biochar, by removing moisture and volatile matter, thereby enhancing its calorific value and making it a more efficient and renewable energy material for future applications. This is further supported by studies showing that torrefaction increases the carbon content and calorific value of agricultural residues like maize and wheat waste, fundamentally improving their fuel properties. Moreover, the utilization of agricultural residues for torrefaction aligns with the principles of a circular economy, reducing dependence on fossil fuels and mitigating environmental pollution. This is particularly relevant given the large amounts of agro-industrial waste generated, which, if not disposed of properly, can lead to environmental contamination. Torrefaction offers a pathway to reuse these residues as biomass for energy production or as adsorbents for environmental decontamination. The process also addresses the inherent challenges of using biomass as fuel, such as its low energy density, high moisture content, and hydrophilicity, by transforming it into a more energy-dense, hydrophobic material with improved grindability, thereby reducing storage and transportation costs. This transformation is crucial for making biomass a viable alternative to conventional fuels in domestic power plants and other industrial applications. Furthermore, oxidative torrefaction, a variation of the process, has been identified as an economical and sustainable option for thermochemical biorefinery applications, offering a way to achieve a circular economy by using waste biomass and flue gas. The process also results in biomass with greater heating values, energy density, and improved physical properties, which significantly reduces transport and storage costs. Research into the chemical modification of agricultural wastes for water decontamination highlights the potential of torrefied biomass as an efficient, cheaper, and renewable adsorbent, further emphasizing the environmental benefits of torrefaction. Studies on the densification of agricultural waste biomasses through torrefaction have demonstrated its effectiveness in converting these residues into valuable, solid biofuels, optimizing conditions for better energy recovery schemes. Lastly, the impact of moisture in the torrefaction atmosphere on biomass thermochemical transformation suggests that the process's efficiency can vary with biomass type and composition, indicating the need for tailored torrefaction approaches to maximize benefits. In summary, the motivations for torrefying agricultural residues include enhancing biomass fuel properties, contributing to environmental sustainability, improving biomass handling and transportation efficiency, and expanding the applications of biomass for energy production and environmental remediation.
