Beschreibung
Zusammenfassung:	A method (100) for pressing at least one article in an arrangement as well as a pressing arrangement (500). The method comprises providing an article inside a load compartment and feeding a pressure medium into the pressure vessel and increasing (140) the pressure in the load compartment; increasing (120) the temperature and maintaining (150) the increased temperature and the increased pressure for selected periods of time (t1, t2); changing (170) the temperature from the first predetermined temperature level to a second predetermined temperature level (T2); feeding (180) a carbon-containing gas into the pressure vessel; maintaining (190) the second predetermined temperature level for a selected period of time (t3); reducing (200) the temperature in the load compartment; and discharging (210) the pressure medium from the pressure vessel and reducing (220) the pressure in the load compartment.
