39 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
