ICM Has Short List for Its Gen 1.5 Cellulosic Ethanol
by Jim Lane (Biofuels Digest) In Kansas, ICM said it is is currently in discussion with a short list of those interested in being selected as an early adopter of its Gen 1.5 technology, and they anticipate construction of the first commercial cellulosic plant of its kind built next to an existing grain ethanol plant in the near future.
ICM’s patent-pending Generation 1.5 Grain Fiber to Cellulosic Ethanol Technology integrates a process for converting corn fiber to cellulosic ethanol with existing ethanol plants. This pathway to cellulosic ethanol starts with ICM’s patented technologies, Selective Milling Technology and Fiber Separation Technology. First, a selective grind of the corn slurry to make the starch and oil more accessible in the entire process. Then, the fiber is separated from the stream by counter flow washing steps.
The Gen 1.5 process sends the fiber stream to a dilute acid pretreatment that breaks down the fiber and makes the cellulose stream accessible for further processing. READ MORE and MORE (ICM) and MORE (Ethanol Producer Magazine/ICM)
