Cheaper and greener biodiesel process

A better biodiesel process has been developed with no waste products and lower costs. Raw fats and oils of any type are combined with an alcohol. This mixture is run through a sulfated zirconia column heated to 300 degrees Celsius. Easy Fatty Acid Removal (EFAR) system recycles any unreacted raw material back through the reactor. Excess alcohol is recycled back through the reactor. Pure biodiesel comes out the end.

The Benefits
• Can utilize a variety of inexpensive, not food grade feedstocks [like fat and garbage food waste]
• Can produce biodiesel in seconds not hours
• Does not produce any waste
• Small in physical size
• No washing, refinging or neutralizing of the biodiesel is necessary [can be 88% of the cost of biodiesel]
• Sulfated zirconia catalyst never needs replacing
The group has formed a company called Ever Cat Fuels and is in the process of building a 3 million gallon per year (MMgy) commercial biodiesel facility with the intention of scaling it up to 30 MMgy in the next 3-5 years. As soon as the Ever Cat plant is producing biodiesel successfully, the group plans on licensing the technology to other interested parties. 1000 larger plants would produce 30 billion gallons per year. The United States currently uses 140 billion gallons of gasoline each year. 1 billion tons of biomass could supply the material for 30 billion gallons per year.
