The Preparation of Colloidal Particles in a Continuous Process : Designing a tubular reactor for the formation of colloidal lignin particles

Abstract

The thesis states a research offered by Aalto University that involves the production of colloidal lignin particles, which have various applications in material industry. The existed process of preparing colloidal lignin particles uses a batch process that does not fit in the purpose of sustainability. Thus, this research project it is intended to develop a continuous process by designing a tubular reactor to improve the preparation of colloidal lignin particles. The experimental results indicate that the tubular reactor has positive effect on formation of colloidal lignin particles in sustainable and energy efficient way. Further study can be carried out by upscaling the current research.
