| Content |
Students enhance their theoretical knowledge with practical aspects of the following exemplary process steps:
- Literature research focusing on the production of bioethanol from lignocellulosic material, especially from wheat straw
- Selection of one pretreatment variant to be performed in lab including discussion on technical limitations
- Create a Design of Experiments (DoE) Approach to investigate influence of selected process parameters on pretreatment efficiency including the definition of response of interest
- Perform corrseponding experiments in lab including the process steps of pretreatment, enzymatic hydrolysis and fermentation to produce Bioethanol
- Perform required analysis to obtain information on process efficiency, performance of enzymatic hydrolysis and finally bioethanol fermentation
- Use statistical software, e.g. Minitab, to evaluate, illustrate and discuss experimental results
- Write a scientific report on the overall topic and results including literature-based discussion
