“…As for XL, it is decomposed over a broad temperature range without obvious peak, which means the oxidation occurs at a relatively low rate during almost the whole temperature range. XL is a kind of inferior coal, including significant C=O and C-H bonds with low energies, which are easier to decompose than C=C bond in BC [6,27].…”

This work presents comparative study on the combustion of biomass pellets (BP) with Bituminous coal (BC), and Xiao longtan lignite (XL) using thermogravimetric (TG) analysis. The results show that the combustion process of BP:BC can be divided into the release and combustion of volatile compounds, oxidation of BP char and combustion of BC char. Whilethere are two stages for the blend of XL and BP, which are the combustion of volatile compounds and the char burning of BP and XL. With increasing BP ratio, the maximum combustion rate and combustion index increase, while the burnout temperature decreases, indicating the combustion performance of coal can be improved. In addition, interactions between BP and XL are more significant than that of BP and BC. The maximum deviations are found to be 30% BP with BC and 10% BP with XL. Reaction mechanisms are analysed using Coats-Redfern method. The first order model is found to be suitable for the first stage of biomass burn (stage 1) and coal combustion of BC:BP blends. Diffusion controlled model D3 and D4 are the most effective for the second stage of biomass burn and XL combustion, respectively. The minimum activation energies of biomass blending is obtained with a BP ratio of 30% for BC and 10% for XL.

“…However, glutamate‐ and aspartate‐based ionic liquids generally have higher glass transition temperatures, melting temperatures, and viscosities. These ionic liquids have potential applications in catalysis, chiral separations, gas separation and purification, CO 2 absorption, oil purification, coal and biomass pretreatment, as biolubricants, and as solvents for organic syntheses, such as Cu‐free Sonogashira coupling reactions or peptide synthesis …”

Protein‐Rich Biomass Waste as a Resource for Future Biorefineries: State of the Art, Challenges, and Opportunities

Protein‐rich biomass provides a valuable feedstock for the chemical industry. This Review describes every process step in the value chain from protein waste to chemicals. The first part deals with the physicochemical extraction of proteins from biomass, hydrolytic degradation to peptides and amino acids, and separation of amino acid mixtures. The second part provides an overview of physical and (bio)chemical technologies for the production of polymers, commodity chemicals, pharmaceuticals, and other fine chemicals. This can be achieved by incorporation of oligopeptides into polymers, or by modification and defunctionalization of amino acids, for example, their reduction to amino alcohols, decarboxylation to amines, (cyclic) amides and nitriles, deamination to (di)carboxylic acids, and synthesis of fine chemicals and ionic liquids. Bio‐ and chemocatalytic approaches are compared in terms of scope, efficiency, and sustainability.

“…Since choline-amino acid ionic liquids (ChoAA-ILs) were introduced in 2012 by Liu et al (Liu et al 2012), the interest in these systems obtained from natural and renewable feedstocks has increased significantly, as witnessed by the large number of papers appeared in the last few years, and some new fields of application have been opened. Indeed, though the use of ChoAA-ILs in the field of biomass processing for which they were originally developed-they possess the amazing property of solubilizing lignin selectively from rice straw-has steadily continued to grow (Hou et al 2013b;Reddy 2015;Wang et al 2016;To et al 2018), the powerful solubilization properties of these liquids were extended to other systems, like drugs (Alawi et al 2015), to the extraction of noxious substances in cigarette smoke (Zhang et al 2016), and to lignite and thermal coal pre-treatment (To et al 2017). In addition, these compounds have found use as lubricants (Mu et al 2015;Jiang et al 2018;Zhang et al 2018;Wu et al 2018), as CO 2 capture agents (Zhang et al 2013;Bhattacharyya and Shah 2016;Saptal and Bhanage 2017), and as antimicrobials (Foulet et al 2016), in topical formulations for drug delivery (De Almeida et al 2017), and they have shown to possess selective antiproliferative activity against some breast cancer cell lines when complexed with hemocyanins (Guncheva et al 2015).…”

Choline-amino acid ionic liquids: past and recent achievements about the structure and properties of these really “green” chemicals

The structure of choline-amino acid ionic liquids, atoxic task-specific solvents composed of materials originated from renewable feedstocks, is reviewed in this letter. The varied and strong interactions that these liquids are capable of establishing are largely dependent on their structure and confer them outstanding solvating properties with respect to a large number of different solutes. Among the experimental methods capable of yielding structural insight, the energy-dispersive version of X-Ray diffraction, that uses the Bremsstrahlung radiation of the X-Ray tube, is a technique very well suited to investigate these liquid systems. The diffraction spectra of five choline-amino acid ionic liquids, recently measured, are reported and discussed; in particular, the presence or absence of the medium-range order pre-peak is related to the presence of polar groups within the amino acid side chain that destroys the hydrophobic interactions between aliphatic chains. In the final section, a recent example of choline-amino acid ionic liquids as for ancient paper preservation and two other interesting results are discussed at the end.
