Mass transport in wood components from processed woods(III-3)

Purpose of the project is to study mass transport of ionic liquids into wood pieces and fibers and consequent lignin and hemicellulose transport out from the pieces. Therefore, characterisation techniques to investigate the location of ionic liquids and lignin in the fiber structure are needed to be developed. Examples of such techniques are X-ray imaging, […]

A multiscale modelling approach aided by X-ray techniques to deepen the understanding of the effect of climate change on the hygromechanical behaviour of wood

Climate change has shown to alter the mechanical properties of wood. This suggest an alteration of the hygromechanical behaviour, behaviour that by itself is not fully elucidated yet. The deeper understanding of the hygromechanics of wood is important in the correct prediction and interpretation of drying and long-term behaviour of this material. In this light,

Design of biochar from residual streams – influence of fuel and process parameters on biochar properties for water and soil applications

Biochar can be used in many applications, including water treatment and soil improvement. The properties of biochar are affected by the conditions during production. In this project, the influence on the properties of the biochar at different process conditions is investigated through the gasification of residual streams from both the forestry and agricultural sectors. The

Improved uniformity of the fibers liberated in the kraft pulp digester 

This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be
