Protic ionic liquids may drive down production cost of cellulosic biofuels [Registered]

Researchers at North Carolina State University have developed a simple, effective and relatively inexpensive technique for removing lignin in the production of cellulosic biofuels, and thereby drive down production costs. Lignin is difficult to break down or remove from lignocellulosic feedstocks. However, that lignin needs to be extracted in order to reach the energy-rich cellulose that is used to make biofuels. “Finding inexpensive ways to remove lignin is one of the largest barriers to producing cost-effective biofuels,” says the lead researcher Ezinne Achinivu. “And our approach is very promising.” The researchers began by making a number of liquid salts called…
