Evolution of Solid Processing Methods in Continuous Flow Technology: Reactive Extrusion
Get PDFThe frustrations of precipitation, fouling and blockages of liquid-based flow reactors is familiar to all researchers that have worked with continuous flow equipment. There have been many innovative solutions to try and circumvent this issue. This short review will highlight the emerging technique of mechanochemistry and reactive extrusion as a continuous process that can directly work on solid (and liquid) materials and elicit chemical transformations
Suppression of Lignin Repolymerisation to Enhance Cellulose Bioconversion and Lignin Valorisation – A Review
Get PDFThe recent discovery that the prevention of lignin repolymerisation/condensation in lignocellulosic biomass pretreatment can both enhance the bioconversion of cellulose and the quality of the obtained lignin, has brought a lignocellulose biorefinery closer to reality. In this work, the development of this approach and the last advancements are reviewed. The review reveals the successful implementation for a wide range of lignocellulosic substrates including softwood, hardwood, and agricultural residues. As well, it is shown that the approach can enhance various pretreatment technologies, including steam, acid and organosolv processes. Recent developments involve the discovery of new and greener additives which prevent lignin repolymerisation, the implementation of cellulose saccharification at industrially realistic conditions and high-yield fermentation. In addition, first applications of the lignin obtained in these processes are reviewed, showcasing its enhanced quality for functionalisation and use in polymers, as well as for its depolymerisation to aromatic monomers. The recent progresses bring closer the prospect of a biorefinery that can valorise all fractions of lignocellulosic biomass

No full textWhat is Philosophy of Chemistry and Why is it Important
Get PDFChemistry is a science fundamentally characterized by the ability of making its own study objects. Chemistry\u27s unique sign language and representations of structural formulas are highly predictive tools. These aspects, together with the richness of qualitative models, make chemistry highly attractive for philosophical studies. However, philosophy of chemistry is, within the philosophy of science, a still relatively young discipline
