Summary:In this work, we introduce high school students to renewable energy through the exploration of the pyrolysis process, focusing on the conversion of lignocellulosic biomass into bio-oil. Students undertake a sequence of straightforward experiments in four sessions, using a handmade reactor and various types of biomasses. Outcomes such as yield calculations and temperature measurements are analyzed. Furthermore, the generated bio-oils are evaluated by measuring their pH, density, and by separating their water and ether components. Their composition is also analyzed using planar chromatography. This educational approach not only enhances students’ comprehension of pyrolysis and bio-oil characteristics but also cultivates their critical thinking and ability to make well-informed decisions in the field of renewable energy.
