    • Ethanol pulping as a stage in the bio-refinery of olive tree prunings 

      Requejo Silva, Ana; Rodríguez Pascual, Alejandro; González, Zoilo; Vargas González, Fátima; Jiménez, Luis (NC State University, 2012)
      Biomaterials from olive tree pruning are an abundant agricultural residue in various Mediterranean regions. A suggested use of this residue is its separation in a main fraction (trunks and stems with diameter > 1 cm) and ...

    • Improvement of TCF bleaching of olive tree pruning residue pulp by addition of a laccase and/or xylanase pre-treatment 

      Martín-Sampedro, Raquel; Rodríguez Pascual, Alejandro; Requejo Silva, Ana; Eugenio, María E. (NC State University, 2012)
      This study aimed at assessing the biobleachability of soda pulps obtained from olive tree pruning residue. The enzymatic (LMS) pre-treatment was applied prior to a simple totally chlorine free (TCF) bleaching sequence, ...

    • Optimization of ECF bleaching and refining of kraft pulping from olive tree pruning 

      Requejo Silva, Ana; Rodríguez Pascual, Alejandro; Colodette, Jorge L.; Gomide, José L.; Jiménez, Luis (NC State University, 2012)
      The aim of the present work was to find an optimum kraft pulping process for olive tree pruning (OTP) in order to produce a bleachable grade pulp of Kappa number about 17. The kraft pulp produced under optimized conditions ...

    • Total use of olive tree prunings by means of hydrotermal and combustion processes 

      Requejo Silva, Ana; Feria, Manuel Javier; Vargas González, Fátima; Rodríguez Pascual, Alejandro (NC State University, 2012)
      The aim of this work is to chemically characterize olive tree prunings and use the material in hydrothermal and combustion processes. The influence of the hydrothermal treatment conditions, with and without acid catalyst, ...
