With the aim of having a global view of the microstructural evolution of wood during soda
pulping and to optimize the sample, a step-pulping process has been performed as a
preliminary step for in-situ inspection. During this experiment, the pulping process was
interrupted each 30 min and the wood chip is taken to be inspected using lab x-ray
tomography. Two main challenges appear during this experiment: the phase contrast is
reduced due to the saturation of samples with water and the the interruption of the
experiment every 30 min having the samples exposed to external conditions, which highly
affects the microstructure. To overcome these challenges, we designed a small scale reaction cell to in-situ inspect the structural changes in wood while the soda-pulping experiment using synchrotron x-ray tomography. The synchrotron X-ray experiment has been performed at Paul Scherrer Institute in Switzerland using TOMCAT beam line. The inspection results abroximatly requires 10 000 GiB to be stored which is not an easy task to be stored in personal computers. The analysis of these data requires super computer to be post-processed using Image J software since all the data are image processing.
