Embodiment 1

[0104] Lignin is extracted from biomass and processed

[0105] Lignocellulosic biomass was treated by sequential ionic liquid pretreatment followed by hydrolysis to produce a cellulose fraction and a lignin fraction. See, eg, US Patent No. 8,030,030 and US Provisional Patent Application No. 61 / 663,315. The lignin fraction is subjected to hydrothermal treatment at about 100-150 ATM and 200-300°C for about 1-30 minutes. The obtained monomeric compounds were analyzed using gas chromatography-mass spectrometry. The results are shown in Tables 1 and 2 and figure 2 A and 2B. Such as figure 2 The obtained product shown in A is further catalytically reprocessed to produce figure 2 Deoxidation chemicals shown in B.

Abstract

The invention discloses a method for creating valuable products from lignocellulosic biomass comprising sequential pretreatment of lignocellulosic biomass with ionic liquid followed by hydrothermal processing of the lignin.

Description

field of invention [0001] The present invention relates to a method for converting lignin into chemicals. Background of the invention [0002] Lignocellulose is the major structural component of plants and includes cellulose, hemicellulose and lignin. In lignocellulosic biomass, crystalline cellulose fibrils are embedded in a poorly organized hemicellulose matrix surrounded by an outer lignin seal. Lignocellulosic biomass is an attractive feedstock because it is an abundant, local, renewable source that can be converted into liquid transportation fuels, chemicals, and polymers. The major components of lignocellulose are: (1) hemicellulose (20-30%), an amorphous polymer of five- and six-carbon sugars; (2) lignin (5-30%), a phenolic compound and (3) cellulose (30-40%), a highly crystalline polymer of cellobiose (dimer of glucose). [0003] Lignin is a complex hydrophobic cross-linked aromatic polymer. In nature, lignin is primarily found as an integral part of the cell wal...
