Optimization of ECF bleaching and refining of kraft pulping from olive tree pruning
(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 ...
Cellulosic pulps of cereal straws as raw material for the manufacture of ecological packaging
(NC State University, 2012)
The aim of this work was to study the potential application of four types of cereal straws: oats, maize, rapeseed, and barley, in order to obtain cellulose pulp through the Specel® process for use in the manufacture of ...
Improvement of TCF bleaching of olive tree pruning residue pulp by addition of a laccase and/or xylanase pre-treatment
(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, ...
Total use of olive tree prunings by means of hydrotermal and combustion processes
(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, ...
Ethanol pulping as a stage in the bio-refinery of olive tree prunings
(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 ...
