  • Hydroxymethylation of technical lignins from south-american sources with potential use in phenolic resins. 

    Taverna, María E.; Estenoz, Diana; Nicolau, Verónica V.; Felissia, Fernando; Area, María Cristina (2019-02-16)
    This work investigates the valorization of sodium lignosulfonate, kraft, and organosolv lignins from South America. A detailed characterization of the lignins and their chemical modification by hydroxymethylation, a reaction ...

  • Improvement of bioethanol production from rice husks 

    Arismendy Pabón, Ana María; Felissia, Fernando Esteban; Mendieta, Carolina Mónica; Chamorro, Ester Ramona; Area, María Cristina (2020-07)
    This work aimed to compare the production of bioethanol from rice husk through simultaneous hydrolysis and fermentation process (SSF) with that through hydrolysis followed by fermentation process (SHF). The raw material ...

    El objetivo de este trabajo fue encontrar las condiciones óptimas de hidrólisis enzimática de la cascarilla de arroz pretratada con hidróxido de sodio en autoclave a 121° C. Se evaluaron las variables: FPU/ g sustrato, pH, ...

  • Optimization of the soda-ethanol delignification stage for a rice husk biorefinery 

    Dagnino, Eliana Paola; Felissia, Fernando E.; Chamorro, Ester Ramona; Area, María Cristina (2017-03-01)
    The aim of this work was to optimize the delignification of the hemicelluloses-free fraction of rice husk to obtain fractions of lignin, cellulose, and inorganics, which could be valorized in the context of the rice husk ...

  • Studies on lignin extraction from rice husk by a soda-ethanol treatment : kinetics, separation, and characterization of products 

    Dagnino, Eliana Paola; Chamorro, Ester Ramona; Felissia, Fernando E.; Area, María Cristina (2018-01-01)
    The delignification kinetics of lignocellulosic waste is an important tool for the study of the technical-economic viability of biorefinery processes. The aim of this work was to study the kinetic of lignin extraction by ...
