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.

Process for manufacturing an upgraded bio-oil from black liquor

The invention relates to a method for preparing an aromatic polyisocyanate in an isocyanate plant comprising a reaction section for a phosgenation reaction, wherein a primary aromatic amine is reacted with phosgene compounds in a reaction section to obtain an isocyanate comprising reaction product and wherein COconcentration in the gases coming from the reaction section is measured and analyzed, and wherein the conditions in the phosgenation reaction are adjusted in case the COconcentration in the gases coming from the reaction section is higher than a background COconcentration.

Method for controlling the process for making isocyanates

A process for extracting a phosgene compound, comprising providing a membrane extracting unit comprising at least one extracting cell that comprises at least one membrane contactor module having at least two sides, a gas side and a liquid side; letting an initial gas stream comprising a phosgene compound flow on the gas side of the membrane contactor module; and letting an extractant liquid stream, suitable for dissolving a phosgene compound, flow on the liquid side of the membrane contactor module so that the extractant liquid stream absorbs the phosgene compound from the initial gas stream and provides a second extractant liquid stream enriched with the phosgene compound.

The present invention relates to a process for the preparation of di- and polyamines of the diphenylmethane series, and to the preparation of di- and polyisocyanates of the diphenylmethane series from these di- and polyamines. The di- and polyamines of the diphenylmethane series are prepared by the reaction of aniline and formaldehyde in the presence of hydrochloric acid. In the present invention, the formaldehyde employed is used as an aqueous solution which contains less than 0.001 wt % of metal ions which are divalent and/or more than divalent.
