The entire process of producing biofuels can be demonstrated with leXsolar-BioFuel Large. It starts with the biological step of alcoholic fermentation. Afterwards the produced mash will be distilled with the help of the leXsolar-condenser, which was developed just for this experiment. The last step demonstrates the conversion of the produced biofuel into usable energy, such as electrical energy, using the provided Ethanol-fuel cell. leXsolar-BioFuel Large does not only cover the topic of the production of bioethanol, but also the production of biodiesel through transesterification of fats.
Experiments:
Part 1: Biodiesel production
Transesterification from fat to Biodiesel (FAME) Determination of fat parameters Extraction of fats from foods and oil plants Part 2: Alcohol fermentation Production of a mash/ alcoholic fermentation Fermentation of different sugar types (including catalytic splitting of starch) Proof of fermentation gases Part 3: Distillation and production of Bioethano Distillation of mash Characteristics of the produced Ethano Part 4: Ethanol fuels Introduction Ethanol fuel cell I-V curve of Ethanol fuel cells Dependency of Ethanol fuel cells on concentration and temperature Energy balance of the whole process
