I'm an expert in the field of renewable energy and biofuels, and I'm here to guide you through the process of converting cooking oil into diesel fuel, specifically biodiesel. Biodiesel is a renewable fuel made from natural oils or animal fats, and it's a cleaner alternative to fossil fuels.
The process of making biodiesal from cooking oil involves several steps. Here's a detailed guide:
Step 1: Collect and Prepare the Oil
The first step is to collect used cooking oil. It's important to use oil that has been used but not contaminated with food particles or water. Collect the oil in a clean container and let it cool down. Once cooled, filter the oil to remove any solid particles.
Step 2: Heat the Oil
Next, you'll need to heat the oil to approximately 95°F. This can be done using an electric burner, as mentioned in the reference material. Heating the oil makes it easier to handle and pour for the next steps. Use a cooking thermometer to ensure the temperature is accurate.
Step 3: Add Methanol
Once the oil is heated, you'll need to add methanol, which is the alcohol component necessary for the transesterification reaction. Methanol is a key ingredient in the production of biodiesel.
Step 4: Add a Catalyst
A catalyst is necessary to speed up the reaction between the oil and methanol. Sodium hydroxide (NaOH) or potassium hydroxide (KOH) are commonly used catalysts. Add the catalyst to the mixture carefully.
Step 5: Mix and Allow to React
After adding the methanol and catalyst, mix the solution thoroughly. Then, allow it to react for a few hours. The reaction will convert the triglycerides in the cooking oil into fatty acid methyl esters (FAME), which are the main components of biodiesel.
Step 6: Separate the Layers
After the reaction is complete, the mixture will separate into two layers: the biodiesel on top and glycerin on the bottom. The biodiesel is lighter and will float on top of the glycerin.
Step 7: Decant the Biodiesel
Carefully decant the biodiesel from the glycerin. This can be done by using a siphon or a pipette to remove the biodiesel without disturbing the glycerin layer.
Step 8: Wash the Biodiesel
To remove any remaining impurities, wash the biodiesel with water. This step is repeated several times until the water runs clear.
Step 9: Dry the Biodiesel
After washing, the biodiesel needs to be dried. This can be done by letting it sit undisturbed for a period of time, allowing the water to settle at the bottom.
Step 10: Filter and Store
Finally, filter the biodiesel to remove any remaining particles and store it in a clean, sealed container.
It's important to note that this process should be carried out in a well-ventilated area and with proper safety equipment, such as gloves and goggles. Additionally, the use of a gas burner is not recommended due to the flammability of methanol.
Now, let's move on to the translation of the above steps into Chinese.

Heat the oil to 95oF. Pour your used oil into a large, clean cooking pot and heat it to 95oF over an electric burner to make the oil easier to pour for filtration. Use a cooking thermometer to monitor the temperature. Don't use a gas burner for this or any other stage of the biodiesel creation process.
