Abstract
A novel approach for biorefining is proposed and the proof of concept is accomplished. Catalytic oxygen atom transfer from non-oxidant lignin to cellulose or hemicellulose by organic chemicals is reported. As expected, the catalytic reaction is a novel method for the selective and quantitative hydrolytic depolymerization of lignocelluloses into liquid products in a one-pot reaction. Lignin is converted quantitatively into small molecular aromatics, simultaneously, cellulose and hemicellulose are converted quantitatively into small organic acids with lactic acid up to 50%. Small molecular aromatics can be converted into diesel blend via one-step methylation. Neither black tar formation nor gasification is observed in the catalytic oxygen atom transfer reactions, conversion of biomass to products is quantitative.
