摘要： The present invention relates to a process for manufacturing an upgraded bio-oil derived from black liquor, comprising the following steps: —Providing black liquor, which comes from the pulp and paper manufacturing industry; —Subjecting black liquor to a pyrolysis treatment with formation of a pyrolyzed black liquor gas and a solid mass, which comprises char and salts; —Catalytic conversion of said pyrolyzed black liquor gas by contacting at least part of the latter with a bi-metallic modified zeolite catalyst with formation of the upgraded bio-oil, which comprises benzene, toluene, xylene (BTX), naphthalene and non-BTX products.

摘要： A process for the preparation of small aromatic compounds from black liquor comprising: providing black liquor that derives from alkaline treatment of wood chips; subjecting the black liquor to a pyrolysis treatment to yield a pyrolysed black liquor gas and a solid mass comprising char and salts in a first reactor, wherein the salts substantially derive from the treatment of black liquor; contacting at least part of the pyrolysed black liquor gas with a catalyst in a second reactor, which is different from the first reactor to provide a conversion treatment to yield a conversion product; and recovering small aromatic compounds from the conversion product.
