Purpose and goal

The aim of the project is to investigate the fractionation of hemicellulose residual streams from the forest industry by CPC Technology (Centrifugal Partition Chromatography), to determine which fractions are obtained with the goal to ultimately use these fractions to produce higher value environmental friendly products. CPC is a liquid-liquid-chromatography where no solid material is included and therefore irreversible binding of plant components and clogging of the process systems is avoided.

Expected results and effects

The main effect expected from the project is to efficiently fractionate hemicellulose residual streams that could then be transformed to high value products that are presently produced from fossil sources. Hemicellulose residual streams from the forest industry could potentially deliver "green" products of approximately 1 million tons per annum. This would benefit both the environment and the economy.

Planned approach and implementation

Samples of residual streams are obtained from forest industry and from within RISE, sample components will be characterised by LC-UV/MS. Methods for CPC separation in analytic scale will then be developed by testing two-phase solvent systems and modifying conditions to achieve the best possible separation of as many sample components as possible. Using semi-preparative CPC 200 mg sample will then be separated. If required the method will be optimised and then scaled up to 2 gram and finally to 10 gram injection to verify scalability. Evaluation by LC-UV/MS after each separation.
