Polyelectrolyte complexes for biocide enhancement

Biorefinery of biomass for value-added products and biofuel plays an important role in the sustainable global bioeconomy. Among various biorefinery processes and platforms, effective separation technologies are key to the economical production of value-added products and biofuel from biomass at a low cost. Amid the several separation technologies available, liquid-liquid extraction (LLE) has been shown to play a vital role in the separation and purification of bioproducts in biomass biorefining processes and has demonstrated many advantages, as compared to other separation technologies. LLE has become a potential technology for biomass biorefinery. Lab-scale and pilot-scale studies of LLE technology in biorefinery have been reported. This review focuses on the applications of LLE technologies in various processes of biomass biorefinery, including extraction and separation of biochemical materials and biofuels from aqueous mixtures and removing fermentation inhibitors from biomass hydrolysates. This review paper aims to offer an up-to-date discussion of the applications, recent progress, potential, and future research directions of LLE in biomass biorefineries. LLE technology is a promising separation technology for biomass biorefineries with a bright future.

Polyelectrolyte complexes comprising natamycine and/or phosphite for biocide enhancement

A process for recovering lignosulfonates from spent sulfite liquor resulting from the cooking of cellulose-containing material comprising extracting the spent liquor with a liquid amine dissolved in a strongly polar ketone, preferably methyl isobutyl ketone, as an organic solvent, which ketone is poorly soluble in water, to form a lignosulfonate-bearing organic phase and an aqueous phase, separating the organic phase from the aqueous phase, recovering the substantially sugar-free lignosulfonates from the organic phase by stripping the organic phase with a base insoluble in the organic phase, regenerating the stripped, lignosulfonate-free organic phase by treating it with an aqueous solution of sodium bisulfite to bring the liquid amine in the phase into bisulfite form and returning the regenerated organic phase for further extraction of spent liquor.
