    • The present invention is embodied in a method for heat-treating pieces of wood or wood products, such as logs, lumber wood chips or wood strands with steam or hot water to kill any plant pests present in the wood or wood products. The pieces are loaded into a hold of a ship equipped to introduce steam or hot water into the hold. In some embodiments, the ship is also equipped to recycle the spent steam or water. The pieces are then contacted with the steam or hot water to raise the temperature of the pieces to a sufficient level for a sufficient period of time to kill any plant pests that might be present.
    • 本发明体现在用蒸汽或热水热处理木材或木材产品如木材,木材木片或木绞线的方法,以杀死木材或木制品中存在的任何植物害虫。 这些件被装载到装备有将蒸汽或热水引入保持器的船的舱内。 在一些实施例中,船还装备有回收废蒸汽或水。 然后将这些碎片与蒸汽或热水接触以将片的温度升高到足够的水平足够的时间以杀死任何可能存在的植物害虫。

    • The present invention relates to a method for continuous acetylation of wood elements. The acetylation is conducted with an acetylation medium at a pressure of at least 1.5 barg in a substantially oxygen free environment. Alternatively, the method according to the invention comprises the steps of: (a) feeding wood elements in a substantially oxygen free environment to a continuous acetylation reactor, and (b) treating the wood elements with an acetylation medium in the continuous acetylation reactor under wood acetylation reaction conditions, at a pressure of at least 1.5 barg. The process according to the present invention allows to acetylate wood elements to a high acetyl content in a very efficient way, without compromising on the quality of the material. The acetylated wood elements can be used in the production of medium density fibreboards with superior qualities such as dimensional stability and durability.
    • 本发明涉及木质元素的连续乙酰化方法。 在基本上不含氧的环境中,乙酰化在至少1.5barg的压力下用乙酰化介质进行。 或者,根据本发明的方法包括以下步骤:(a)将木质元素在基本上不含氧的环境中进料到连续乙酰化反应器,和(b)在木材下的连续乙酰化反应器中用乙酰化培养基处理木质元素 乙酰化反应条件,压力至少为1.5巴。 根据本发明的方法允许以非常有效的方式将木质元素乙酰化成高乙酰基含量,而不会影响材料的质量。 乙酰化木质元素可用于生产具有优良品质如中等密度纤维板的尺寸稳定性和耐久性。
