Summary of xylan/glucan pathway

• Furfural fuel yields presently 80% of theoretical maximum • Limiting yield: xylan losses during pretreatment

• LA fuel yields presently 70% of theoretical maximum • Relatively low selectivity in LA production

• Preliminary economics are not competitive with petroleum • Also not astronomical (MSP ~ $5.00 /gallon)

• Warrants future consideration as a pathway to distillates
