The process to create Biodiesel Fuel





Top 5 Reasons Why Smart Customers Are Using Biodiesel

• Biodiesel is America’s first domestically produced, commercially available Advanced Biofuel and meets EPA requirements

• U.S. biodiesel reduces lifecycle carbon emissions by over 50 percent compared to petro diesel

• Not sacrificing food for fuel
• Biodiesel is produced from a variety of renewable resources and by‐products of producing food for humans and animals
• From the soybeans used to produce biodiesel, 81% of the soybean’s yield is protein that enters the market for either human consumption or animal feed.

• Reduces our dependence on foreign oil
• Expands and diversifies our domestic refinery capacity
• Most economical option for turning oils and fats into usable fuel diesel applications
• Creates added outlets for farm‐based products
• Creates U.S. manufacturing jobs

• Drop‐in replacement for diesel fuel
• No vehicle modifications needed
• Similar, seamless performance compared to diesel
• Dispensed through existing fueling stations
• 30‐40 percent fuel efficiency gains with diesel engine


Viesel’s novel integrated continuous stirred tank reaction (CSTR) process involves packed-bed resin columns in series with a sulfur removal design for the continuous production of high quality biodiesel. As compared to the existing commercialized processes, the system requires less energy by using enzymes as the catalyst. It has the capability of converting unconventional feedstocks into biodiesel. The system is operated in a continuous flow mode and very small amount of enzymes are used, consequently reducing operational cost in production of biodiesel. There is no waste water generated either in the production or in the purifi cation process which makes the process environmentally friendly. Another major breakthrough of the process is that high sulfur content (up to 1000ppm) in the low grade feedstocks (e.g. brown grease) can be reduced below 15ppm.
