Impregnation and chemical modificaion of biobased materials

Internationally unique equipment for chemical modification of biobased materials. The testbed can also be used for conventional pressure impregnation. Primarily focused on treatments of wood for outdoor use.

The testbed consists of two facilities:

  • A pilot plant for modification of wood and wood fibres such as acetylation and furfurylation. The facility is also used for conventional pressure impregnation and microwave drying.  It is an autoclave equipped with both mantle heating and microwave heating with a length of about 2.0 m and a diameter of 0.6 m.
  • A pilot plant for pressure impregnation of wood. The autoclave is 2.0 m long and 0.44 m in diameter. The volume is just over ½ cubic meter.  Impregnation is usually carried out in pods (0.25 x 0.30 x 0.50-2.0 m)
