A method for treating a pulp web in a paper or tissue machine with an extended-nip press unit. This extended-nip press unit includes a shoe press roll with a revolving press belt and a backing roll, where the pulp web is dewatered in the extended press nip between the backing roll and the press belt and where the pulp web is carried on the revolving press belt of the press roll after the extended press nip to a transfer fabric that receives the pulp web. The transfer fabric is guided over a stationary transfer device in the transfer area. A corresponding device for treating the pulp web.

The invention relates to a tubular reactor with a rotating reactor chamber () for thermal treatment of biomass. It is characterized by the reactor chamber () being subdivided into zones by ring-shaped plates (). These zones cause the particles to be retained in a particular area and thoroughly mixed there, i.e., the particles being treated are homogenized and the retention time also becomes more homogenous.
