摘要： Methods and systems for obtaining exhaust streams from wood drying processes and controlling emissions in exhaust streams from wood drying processes are provided. Methods and systems can include pre-treatment steps, such as removing particulate matter and/or heating a process exhaust stream from a wood dryer, in order to obtain an exhaust stream that is suitable for downstream recovery of terpenes from said exhaust stream. Exhaust streams can be contacted with a sorbent to remove volatile organic compounds, and other emissions, generating a purified air stream that is able to be released into the environment without further purification or oxidation.

摘要： A process for treating wood strands suitable for producing OSBs includes treating the wood strands in water at a temperature in the range from 50° C. to 100° C. The present invention likewise relates to a process for producing wood-based OSBs, in particular wood-based OSBs having reduced emission of volatile organic compounds (VOCs), including: a) production of wood strands from suitable timbers; b) treatment of at least part of the wood strands with water; c) drying of the wood strands which have been treated with the water; d) coating of the wood strands which have been treated with water and dried and coating of wood strands which have not been treated with water with at least one binder; e) scattering of the glue-coated wood strands on a conveyor belt; and f) pressing of the glue-coated wood strands to give a wood-based OSB.

摘要： The invention relates to an enzymatic composition and also to a method for seasoning wood, intended in particular for applications in the food industry. The method consists in immersing green wood in an aqueous solution comprising an enzymatic composition. The wood can subsequently be dried very rapidly in a drying facility. The invention makes it possible to improve the aromatic characteristics of the wood by eliminating certain substances judged to be undesirable due to their astringent nature or bitter nature, and transforming them into neutrally-tasting molecules.

摘要： A process for treating wood involving impregnation of the wood with a preservative followed by the heat-fixation of the preservative in the wood using a pre-heated aqueous heat transfer fluid to effect the heat fixation of the preservative. The process particularly relates to steps which are taken to reduce the level of any contamination of the aqueous heat transfer fluid resulting from any wood extractives, any unfixed preservative and/or any particulate matter (i.e. "sludge") that may be present in the fluid. The contamination is preferably reduced by incorporating in the heat transfer fluid an oxidant which will preferentially oxidize any wood extractives resulting from the contact of the treated wood with the fluid without any significant reaction occurring between the oxidant and the preservative. Useful oxidants include inorganic chlorate salts such as sodium chlorate.

摘要： An improved process for the fixation of preservatives in wood is disclosed which initiates the fixation process in the fixation vessel by the application of sufficient pressure to substantially obviate a thermal expansion effect of the treated wood; contacts the treated wood in the fixation vessel with an aqueous liquid heating medium preheated to a temperature of about 130.degree. to no more than about 200.degree. F. for a period of thirty minutes to about two hours; removes the aqueous liquid heating medium from the fixation vessel; applies a vacuum in the range of 10-30" Hg for a duration of up to about 30 minutes; and rinses the treated and fixed wood in said fixation vessel with heated clean water, heated to a temperature of about 200.degree. F.

摘要： A rotary separation devise deploys a drum with mesh like opening on the cylindrical surfaces and a removable cover or cap for filling in an upright position and removal of product or spent matter in an inverted position. When the drum is loaded with material, and the cover closed, it is rotatable to a horizontal position, and disposed in an outer container. The drum is rotated in the horizontal position to initiate the separation process. The outer container may be formed by the mating engagement at a common rim of an upper and lower vessel that form the sealed container.

摘要： A delignified wood material is formed by removing substantially all of the lignin from natural wood. The resulting delignified wood retains cellulose-based lumina of the natural wood, with nanofibers of the cellulose microfibrils being substantially aligned along a common direction. The unique microstructure and composition of the delignified wood can provide advantageous thermal insulation and mechanical properties, among other advantages described herein. The thermal and mechanical properties of the delignified wood material can be tailored by pressing or densifying the delignified wood, with increased densification yielding improved strength and thermal conductivity. The chemical composition of the delignified wood also offers unique optical properties that enable passive cooling under solar illumination.
