Feedstock selection plays a key role in the successful production of biodiesel. Virgin vegetable oils are ideal for production because they are clean, pure and need little or no pre -treatment.Used edible oils, are less expensive, but require more attention, as their chemical and physical properties can vary between collection sites. Animal tallow represents the least costly feedstock, but requires pre and post production treatment.
The following information represents the requirements of the feedstock oil and raw materials used in the CPU:
• Oils and fats of vegetable or animal origin
• FFA content < 1.5%
• Water content < 0.1%
• Free from solids and other substances
• Methanol: Technical grade
• KOH (potassium hydroxide)
