Master Thesis - Optimization of Alkaline Fractionation of Hemp for Fiber Extraction Using Response Surface Methodology

Your Job:

Biomass fractionation is a key step in biorefinery processes enabling the efficient utilization of lignocellulosic biomass by separating it into its main components - cellulose, hemicellulose and lignin - for various applications. Alkaline fractionation, especially using sodium hydroxide, is a well-established method for non-wood biomass due to its strong delignification capability and its ability to swell cellulose.
In this thesis, you will work on the low energy alkaline fractionation of hemp to extract fibers. The goal is to optimize this process using Design of Experiments (DoE), in combination with Response Surface Methodology (RSM). The focus will be on detailed characterization of the extracted pulps as response variables for statistical evaluation

Your tasks in detail:

• Conduct alkaline-organosolv fractionation of hemp under various conditions
  
• Characterize raw hemp and extracted pulps using established analytical protocols
  
• Apply RSM and perform statistical analysis (ANOVA) to optimize the process
  
• Use and compare different analytical techniques for evaluating pulp quality characteristics
  
• Document experimental data and present results in a structured and clear way

Your Profile:

• Interest in biomass processing
  
• Enrolled in a Master`s program in Biotechnology, Chemistry, Chemical Engineering, or a related field
  
• Solid laboratory skills and hands-on experience with analytical instruments (e.g., HPLC, UV/Vis etc.)
  
• Basic understanding of statistical methods and experimental design for data analysis

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:
