Process Intensification of Thermoplastic Lignocellulose Production through High-Solids Reactive Extrusion Enabled by a Novel Recycle Loop

To reduce the reactant concentration necessary for producing a newly synthesized thermoplastic lignocellulose from forestry waste, this study explores concept of recycle stream as chemical unit operation in reactive extrusion process. Modified first pass was returned to start process act lubricant feedstock. By action, high content could be extruded without requiring costly lubrication alternatives such plasticizing additives, solvents, or excessive quantities liquid reactants. With 25% recycled material, significantly improved processing state found, allowing reduction total usage by 50% change degree modification and ultimately leaving less unreacted species final product. The nature modified characterized thermal rheological analysis found demonstrate greater flowability with any fraction.
