Preparation and use of lignocellulose nanomaterials in energy storage devices

Cellulose nanomaterials (CNs) obtained from fully-bleached (lignin-free) chemical fibers, such as cellulose nanoparticles (CNPs), cellulose nanofibers (CNFs), microfibrillated cellulose (MFC) have been a topic of extensive research during last decades since they constitute a biodegradable, renewable and naturally abundant resource with an important scientific and technological potential. However, the bleaching process is an energy-intensive process […]

Efficient Washing of Paper grade pulp in the kraft process

TREESEARCH

The project contributes to strengthened Swedish competitiveness through its expected research results and new fundamental knowledge for the development of an efficient pulp washing process and thus through an increased pace of innovation in the transition to a circular economy. After pulping the wood chips, the resulting pulp fibres and cooking liquor are separated in a

The kinetics of lignin extraction in oxygen delignification.

TREESEARCH

The current and future environmental challenges call for improved and more sustainable processes in the pulp industry. To contribute to a sustainable and competitive Swedish bioeconomy the pulp industry needs to increase efficiency without increasing the use of hazardous chemicals. Oxygen delignification is a unit process that has been used in pulp mill fiberlines between
