Abstract: A process for the production of organic chemicals and fuels from lignin in the presence of a molybdenum or tungsten based catalyst, comprising mixing the lignin with the catalyst and a solvent in a sealed reactor, introducing an inert gas or hydrogen to the reactor to replace oxygen therein, and heating the sealed reactor to perform a depolymerization reaction at a reaction temperature of above 200° C. to obtain liquid products, which include aromatic compounds, esters, alcohols, monophenols and benzyl alcohols.

Abstract: A subgroup VI element to prepare a catalyst for the production of organic chemicals and fuels from lignin with the involvement of solvent molecules. The catalytic reaction use a catalyst composed of a molybdenum or tungsten compound as the active phase, with mixing a kind of lignin, a catalyst, and a reactive solvent. An inert or reductive gas such as H2, N2 or Ar is used to purge or fill the reaction vessel. The temperature is above 200° C., the reaction time is sufficient. The liquid product is separated and analyzed; a catalytic process with a very high product yield, up to 90% if calculated accounting the parts from lignin of the product molecules, or up to over 100% if calculated as the mass products. The product includes aromatic compounds, esters, alcohols, monophenols and benzyl alcohols in different ratios according to the composition, the solvent and the other reaction conditions.
