An organosolv process for producing bio-products by decomposing lignocellulosic materials comprises providing an initial lignin solvent with water, an acid, and a lignin dissolving chemical comprising at least one of an organic ester, butyl acetate, an organic furan, and furfural. The process also includes placing the lignin solvent in contact with a biomass to form a circulation solvent, and recycling at least a portion of the circulation solvent by circulating the circulation solvent back into contact with the biomass. The circulating of the circulation solvent occurs for a period of time, after which, the process then includes separating material such as chemicals and lignin from the circulation solvent. The chemicals can be recycled as new solvent or sold while lignin can be used as natural and renewable colorant for polymers such as poly lactic acid.

The present invention is a process and apparatus for forming various bio-products from cellulosic plant material. The plant material is subjected to a pulping step in which lignin is extracted from the material by an aqueous lignin solvent to form a lignin-solvent mixture and purified cellulose. The lignin-solvent mixture can be separated from the water to form a high energy density fuel that can be used independently or combined with biodiesel. The purified cellulose can be used in conventional processes, e.g., paper making, or can be converted to fermentable sugars with a cellulase enzyme to produce other bio-products depending on the operating conditions of the fermenter. The bio-products produced by the fermenter can include the solvent that may be recycled for use in extracting the lignin.

Agricultural residues (biomasses) have come-up as potential valuable renewable resources for transformation into many bio-products. To achieve this goal, the isolation of major biopolymers in their purest form through an economical process is demanded for synthesis of the target fine chemicals without impurities. However, the difficulty of fractionating the biomass into cellulose, hemicellulose and lignin by a simple method has greatly limited their isolation from agricultural residues. Also, the lipids and waxes present on the surface of the agricultural residues protect it from external chemical and microbial agents. To overcome this issue, the lipids and waxes have been isolated from the biomass through two step organic solvents extraction. Thereafter lignin, hemicellulose and cellulose are isolated successively from the de-waxed biomass.
