摘要： A catalytic method is disclosed for the valorization of lignin. The method comprises subjecting lignin to a catalyzed hydrothermal conversion reaction, said reaction being conducted in the presence of water at an alkaline pH > 8 and a temperature of 200°C-300°C, under the influence of a noble metal catalyst comprising a carbon support. The same reaction can also be applied to subsequently defunctionalize one or more phenolic compounds, notably guaiacol, so as to produce six-membered cyclic hydrocarbons, such as phenol.

摘要： Methods of depolymerizing lignin and products obtained therefrom. The methods include reacting lignin in a liquid solvent comprising an oxidation catalyst with the solvent being in contact with O 2 gas. The solvent can include aprotic polar solvents. The oxidation catalyst can include heterogeneous catalysts. The methods can be used in the oxidative catalytic fractionation of raw biomass to generate soluble aromatic monomers and a solid carbohydrate residue.

摘要： The process includes pretreating the biomass to provide a fluidized biomass. The fluidized biomass is then subjected to high frequency pulses and shear forces without denaturing/degrading the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation such as with hydrogen peroxide and base at a pH above 7. The second fractioned biomass is then subjected to compressive forces to provide water soluble lignin which may be precipitated by reducing the pH.
摘要翻译：该方法包括预处理生物质以提供流化的生物质。然后将流化的生物质经受高频脉冲和剪切力，而不会使生物质的各个组分变性/降解。然后对生物质进行压缩力以将第一液体馏分与第一分馏生物质分离。第一分馏生物质可再次经受与先前相同的高频脉冲和剪切力，特别是如果第一分级生物质中仍存在半纤维素和/或糖。压缩力用于将第二液体馏分与第二分馏生物质分离。第二分级生物质经过氧化，如过氧化氢和碱处于高于7的pH值。然后将第二分级生物质进行压缩力以提供水溶性木质素，其可通过降低pH而沉淀。

摘要： The invention relates to a method for producing phenols, aldehydes, esters and/or ketones with the utilization of lignin and/or lignin sulphonic acid in which the starting materials containing lignin or the lignin sulphonic acid are heated. The desired substance is evaporated from said starting materials, while acceptable products are produced from the solid components of the starting materials by means of heat action. In addition, the originated boundary conditions which stimulate the desired substance are adhered to. Said boundary conditions are abnormal but innocuous for producing the acceptable products from the solid components of the starting materials.

摘要： The present disclosure provides for methods for depolymerizing lignin to produce other useful products. For example, low molecular weight aromatic and aliphatic hydrocarbons ( e.g ., hydrocarbons having 8 to 20 carbon atoms (C8 to C20 hydrocarbons)) as well as oil products can be produced using methods of the present disclosure. The method can include treatment of the lignin using a catalyst composition, where the catalyst composition comprises a persulfate salt and a transition metal catalyst.
