Procedure: Lab report: To produce biodiesel by using used cooking oil Aim: Biodiesel is produced by heating up the used cooking oil. Hypothesis: Fixed variable: The amount of oil used Manipulated variable: Types of oil Responding variable: The time taken for the fire to extinguish Variables: 100 ml of methanol, 2 g of NaOH, used cooking oil, kain sumbu, bunsen burner, retort stand, beakers, measuring cylinders, evaporating dish, aluminium can, lighter List of materials & apparatus: Diagram: Result: Oils and Gas

Light it up , it means that the ng using diesel : Used cooking oil can produce high quality of biodiesel Conclusion: Pure biodiesel contains less energy on a volumetric basis than petroleum diesel. Therefore, the higher the percentage of biodiesel (above 20%), the lower the energy content per gallon. High-level biodiesel blends can also impact engine warranties, gel in cold temperatures, and may present unique storage issues. Since biofuels are made from animal and vegetable fat, more demand for these products may raise prices for these products and create a food crisis in some countries. For e.g., the production of biodiesel from corn may raise its demand, and it might become more expensive, which may deprive poor people of having it. Information:
