Patent number: 11287184Abstract: The invention involves an apparatus and a method for drying and/or curing impregnated wood. The apparatus includes a chamber comprising a stack containing space for containing a plurality of elongated wood planks arranged in a stack of a height Hs, width Ws and length Ls, a heating element arranged within or adjacent to the space, a flow generating device arranged outside the space and configured to generate a circulating flow (F) of curing fluid within the chamber and a fluid flow restrictor arranged between the space and the flow generating device. The flow generating device and the fluid flow restrictor are further configured such that the circulating flow (F) of curing fluid is guided through the heating element generating a homogeneously heated and distributed flow (F) of curing fluid in the space. At least one motor is arranged outside the chamber, the at least one motor being configured to operate the flow generating device via a connecting shaft.Type: GrantFiled: May 16, 2018Date of Patent: March 29, 2022Assignee: Kebony ASInventors: Per Brynildsen, Karl Christian Kristiansen

Patent number: 9156185Abstract: Furfurylated wood produced in a two-chamber system in which monomer/oligomer impregnation in an impregnation chamber is followed by successive stages of drying and curing. Physical properties of wood under treatment are measured, recorded and referenced into a database that accumulates wood species data relating to applied temperature and pressure profiles, physical properties and appearance of intermediate and finished samples of wood and also chemical treatment regimes, including soak time and monomer/oligomer concentrations. During drying and curing, monitoring of process parameters, including water removal and/or atmospheric conditions, are used by a controller both to control and determine a state of process completion by comparing recorded data with historically accumulated data or process set point conditions.Type: GrantFiled: April 9, 2010Date of Patent: October 13, 2015Assignee: Kebony ASAInventors: Rune Bendiktsen, Morten Eilertsen, Per Brynildsen

Patent number: 8197948Abstract: A furan polymer impregnated wood which is uniform in color and density throughout the treated zone. In order to obtain the polymer impregnated wood, a parent wood has been impregnated with a mixture containing polymerizable organic compounds of at least furfuryl alcohol and one further compound. The invention also relates to a method for preparing a furan polymer impregnated wood and uses thereof.Type: GrantFiled: March 2, 2010Date of Patent: June 12, 2012Assignee: Kebony ABInventor: Marc H. Schneider

Patent number: 7858203Abstract: A furan polymer impregnated wood which comprises wood impregnated with a polymerizable furfuryl alcohol monomer mixture containing at least water and furfuryl alcohol, and an initiator selected from the group consisting of anhydrides, acids and combinations thereof is described. For longer storage life, the mixture contains a stabilizer selected from sodium carbonate, sodium bicarbonate, sodium citrate, phosphates and water-soluble lignin derivatives such as calcium and ammonium salts of lignosulfonic acids, and combinations thereof. A method for preparing a furan impregnated wood and uses thereof is also described.Type: GrantFiled: July 21, 2003Date of Patent: December 28, 2010Assignee: Kebony ASAInventor: Marc H Schneider
