Process and catalyst for producing phenolic building blocks from lignin

The present invention relates to a process for the catalytic decomposition of lignin with high yield and high selectivity for phenolic structural units and with minimal formation of coke fractions, and to a catalyst suitable for use in the process. The catalyst comprises an alkaline support material, platinum in a weight percentage of 1-10% by weight and nickel in a weight percentage of 0-5% by weight. The method comprises: providing a reaction mixture comprising lignin, the catalyst, and a solvent; and heating the reaction mixture in order to obtain a mixture comprising a product mixture, the catalyst and the solvent. 本发明涉及一种用于木质素的催化分解的方法，该方法对酚类结构单元具有高产率和高选择性，并且焦炭级分的形成最少，并且涉及一种适用于该方法的催化剂。该催化剂包含碱性载体材料、重量百分比为1重量％-10重量％的铂以及重量百分比为0重量％-5重量％的镍。该方法包括：提供包含木质素、该催化剂和溶剂的反应混合物；以及加热该反应混合物，以便获得包含产物混合物、该催化剂和该溶剂的混合物。
