| titleOfInvention | Catalyst free organosolv process, system and method for fractionation of lignocellulosic materials and bioproducts recovery |
| abstract | A catalyst free organosolv process for a more efficient delignification and bio-product production by fractionating lignocellulosic materials comprises of providing one or more lignin dissolving chemicals with water and placing it in contact with lignocellulosic biomass. The process also includes producing used solvent as a result of placing biomass in contact with lignin dissolving chemicals and water, separating it into organic and aqueous layers, extracting poly lignin from the organic layer to produce recyclable lignin dissolving chemicals, and extracting dissolved solid from the aqueous layer to produce recyclable water. The catalyst free organosolv process can use any combination of fresh, used, or recyclable water and lignin dissolving chemicals, with or without any pH adjustment and placing them in contact with any biomass in process, or any new biomass. The recyclable lignin dissolving chemicals can be further separated to remove any excess or desired organic chemicals from it. The separated chemicals can be recycled as new lignin dissolving solvent or sold, while poly lignin can be used as a natural and renewable colorant for other polymers such as poly lactic acid, or can be mixed with other polymers as an additive and be compounded, co-extruded, injected to make consumable polymeric parts, or can be used as a natural source of renewable aromatics. Application of the catalyst free organosolv process helps to preserve fiber strength which is important for certain applications. At the end, the catalyst free organosolv fractionation process produces good quality fibers, various organic chemicals, and poly lignin that together make the process very economically attractive. |
