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. © 2015 Elsevier Ltd.

Black liquor from the kraft process facilitates quantitative biomass hydrolysis converting cellulose and hemicellulose into organic acids such as lactic acid (~50%), and lignin into small molecular aromatics, without gasification and black tar formation. Oxygen transfer between lignin and carbohydrates may be the mechanism. With this method, three tons of lignocellulosic biomass can potentially produce up to one ton of lactic acid, and one ton of small molecular aromatics. This novel usage of black liquor is environmentally viable because it is accompanied by significant emission reduction of particulates, sulfur and nitrogen oxides, most organic sulfur compounds and sulfites of black liquor were converted into sulfates. © 2012 Elsevier Ltd.

The invention provides a process for direct liquification of cellulosic biomass, which may be used to liquefy all of the organics in cellulosic biomass, including all high molecular polymeric components such as carbohydrates and lignins, into small molecular organics in a short time under mild conditions. In other words, there is provided a technology capable of converting cellulosic biomass into oil. The resultant renewable high-quality oil may be converted into liquid fuels such as gasoline etc., or used as starting materials in chemical engineering industry. The technology for direct liquification of cellulosic biomass as disclosed in the invention is the first one-step process in the world for direct liquification of cellulosic biomass without black tar formation and gasification.
