Polarity is conveniently characterized by the Kamlet-Taft parameters that is, the hydrogen bonding acidity (<em>α</em>), the basicity (<em>β</em>), and the polarizability (<em>π∗</em>). Obtaining Kamlet-Taft parameters is very important for designer solvents, namely ionic liquids (ILs) and deep eutectic solvents (DESs). However, given the unlimited theoretical number of combinations of ionic pairs in ILs and hydrogen-bond donor/acceptor pairs in DESs, experimental determination of their Kamlet-Taft parameters is impractical. To address this, the present study developed two different machine learning (ML) algorithms to predict Kamlet-Taft parameters for designer solvents using quantum chemically derived input features. The ML models developed in the present study showed accurate predictions with high determination coefficient (R<sup>2</sup>) and low root mean square error (RMSE) values. Further, in the context of present interest in the circular bioeconomy, the relationship between the basicities and acidities of designer solvents and their ability to dissolve lignin and carbon dioxide (CO<sub>2</sub>) is discussed. Our method thus guides the design of effective solvents with optimal Kamlet-Taft parameter values dissolving and converting biomass and CO<sub>2</sub> into valuable chemicals.</div></div>","PeriodicalId":66474,"journal":{"name":"Green Chemical Engineering","volume":"6 2","pages":"Pages 275-287"},"PeriodicalIF":9.1,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They mainly consist of Brewer's spent grains (BSG) and Baijiu distiller's grains (BDG), with annual production totaling tens of millions of tons. Recycling these residues effectively is crucial for the environment, society, and industry. Given their unique characteristic of concentrated carbon and nitrogen sources, valorizing AIRs into biocarbon products through thermochemistry is the most sustainable method for waste management, resource recycling, and green ecology. In this review, the preparation and properties of AIRs-derived biocarbon products are systematically discussed. Recent advancements in the green thermochemical valorization of AIRs into biocarbon products for various applications like thermal utilization, environmental remediation, and energy storage are comprehensively reviewed. It is suggested that hydrothermal carbonization, coupled with necessary chemical functionalization (<em>e.g.</em>, using metal oxides and oxysalts), would be a preferable strategy for producing desired functionalized biocarbon for use as carbon adsorbents (for wastewater treatment) and carbon fertilizers (for soil conservation). The yield and quality of functionalized biocarbon can be ensured through the directional regulation of the migration of essential elements like carbon and nitrogen. The co-generation of nitrogen-doped biochar and nitrogen-enriched liquid fertilizer using innovative hydrothermal strategies is identified as a potential research avenue to achieve the full and cascading utilization of AIRs. This review aims to provide an overview and insights into thermochemically valorizing AIRs alongside other light industrial residues for relevant researchers.</div></div>","PeriodicalId":66474,"journal":{"name":"Green Chemical Engineering","volume":"6 4","pages":"Pages 456-472"},"PeriodicalIF":7.6,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144917211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional CO<sub>2</sub> capture methodologies which rely on using sorbents to capture CO<sub>2</sub> from point sources while effective in curbing the rate of CO<sub>2</sub> increase, fall short of achieving net reduction. The last decade has witnessed a surge in the development of chemical sorbents cycled through adsorption-desorption processes for CO<sub>2</sub> extraction from low-concentration sources like air (<em>e.g.</em>, Direct Air Capture (DAC)). However, the efficiency of these technologies hinges on the creation of next-generation materials. Graphene, a revolutionary material discovered about two decades ago, offers great promise for CO<sub>2</sub> capture and conversion. This single-atom-thick sheet of sp<sup>2</sup>-hybridized carbon atoms has unique and tuneable properties, solidifying its position as the most extensively studied nanomaterial of the 21<sup>st</sup> century. This review provides a comprehensive overview of the developing field of graphene-based materials for CO<sub>2</sub> capture and conversion. The discussion begins with an exploration of the synthesis techniques for graphene and the integration of foreign elements to tune its properties for targeted applications. Subsequently, the review discusses the utilization of graphene and its derivatives in both CO<sub>2</sub> capture and conversion processes, encompassing photocatalytic and electrocatalytic conversion methods. Despite the immense potential, the practical implementation of graphene-based DAC necessitates further exploration and development. Notably, engineering efficient of graphene-air interfacial contact is paramount to expediting the deployment of DAC as a viable strategy for mitigating climate change.

In this work, a novel coagulation-flotation combined process was developed to treat the suspended particles as well as significantly reduce organic pollutants content in the actual high-salt organic wastewater. Four typical inorganic and organic flocculants (poly aluminum chloride (PAC), poly ferric sulfate (PFS), polyacrylamide (PAM), and modified cationic starch (CS)) were selected for compounding to obtain an optimized flocculation system for high-salt wastewater. The results showed that the PAC-PAM with a 10:1 ratio in mass exhibited the best coagulation behaviors with the removal efficiency of turbidity and chemical oxygen demand (COD) being 95.33% and 9.21%, respectively, under the optimal operation conditions, and the sedimentation process of coagulant conformed to the quasi-second-order kinetics. The PAC-PAM flocs exhibited stronger netting, sweeping, and adsorption bridging capabilities, which were conducive to removing suspended particles. When the flotation was conducted after coagulation, the COD decreased significantly by 20.82%. In addition, this combined process could reduce the treatment time by 50% compared to the process with only coagulation treatment. During the flotation process, floc particles companies with hydrophobic polycyclic aromatic hydrocarbons could collide and adhere to microbubbles and be floated to the surface, resulting in an effective reduction of COD.
