Researchers find success in pretreating mixed feedstock pellets

By Staff | April 04, 2013

Researchers from the U.S. DOE’s Joint BioEnergy Institute led by Berkeley National Laboratory and the Idaho National Laboratory have demonstrated that iconic liquid is an effective method for pretreating a mix of biofuel feedstock that has been densified into pellets.


“Our results show that an ionic liquid pre-treatment can efficiently handle mixed feedstocks that have been milled and densified into pellets, and can generate high yields of fermentable sugars regardless of upstream processing,” says Blake Simmons, a chemical engineer who heads JBEI’s Deconstruction Division. “This indicates that blending and densifying a wide range of feedstocks has significant potential for helping to make biofuels a cost-competitive transportation fuel technology.”
