Abstract
The invention relates to a process for extracting xylan compounds from comminuted wood components using hydrothermal extraction, wherein the hydrothermal extraction is carried out in a fixed-bed reactor with rapid circulation.
Claims16
A method for extracting xylan compounds, which can be converted into pentosan polysulphate by a subsequent sulfatization, from comminuted wood components using hydrothermal extraction,
- wherein
- the hydrothermal extraction is carried out in a pressure reactor system for heterogenous reactions in a discontinuous operating mode, and
- wherein the hydrothermal extraction is carried out by a bath circulation of the aqueous extracting agent in the pressure reactor system, wherein the pressure reactor system is implemented as a fixed-bed reactor (1).
