leXsolar-BioFuel Large

Item number: 1702


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.
