An apparatus for air flow generation for scent output is described. The device includes a scent system, a speaker, and an output channel. The scent system and the speaker share the output channel, and the speaker is to move air to release scent from the device. A membrane of the speaker may vibrate to produce the air flow.

Air flow generation for scent output

The invention relates to a method for treating wood in order to improve its properties of use and storage, and to thus obtained treated wood product. In the method the wood to be treated is contacted with a treatment composition comprising monoester, diester or triester or a mixture thereof formed by a water soluble C-Calcohol and formic acid as an equilibrium solution. In addition, the invention relates to specific treatment solution compositions.

Biocidal composition for wood, method for wood treatment, and wood produced thereby

The invention relates to a process for the recovery of concentrated high purity formic acid having a concentration of at least 50%, most preferably at least 95%, from biomass wherein an aqueous liquid mixture containing levulinic acid and possibly furfural is subjected to a liquid-liquid extraction step, followed by the recovery of furfural, formic acid and levulinic acid.

Process for recovery of formic acid

Processes for the recovery of formate salt from biomass and the product obtained thereof generally include subjecting an aqueous liquid mixture containing levulinic acid, formic acid and possibly furfural to a liquid-liquid extraction process, followed by the recovery of the furfural, the formate salt and the levulinic acid or the levulinate salt.

Process for preparation of formate salt

According to the invention, wood material is treated with a composition comprising at least one C1-C7 monocarboxylic acid or a salt, or mixtures thereof, and at least one chelating agent. These compounds are dissolved in a liquid aqueous vehicle. In this manner, the treated wood is endowed with excellent resistance against detrimental environmental effects.

Composition and method for treating wood

The invention relates to a method for preparing a reducing agent composition, which is used in the selective catalytic reduction of nitrogen oxides and which contains from 20 to 40% by weight of urea, from 20 to 40% by weight of ammonium formate, and water. The composition is prepared by adding urea to the aqueous solution of ammonium formate that is prepared in situ, and by preparing the aqueous solution of ammonium formate using, as starting materials, a source of ammonium, a source of formate, and water.

Method for the preparation of a reducing agent composition

The invention relates to a reducing agent composition for use in the catalytic reduction process of nitrogen oxides in exhaust gases, the composition containing 20-40 w % of urea, 19-40 w % of ammonium formate, and water.

Reducing Agent Composition

The invention relates to a catalytic process for reducing nitrogen oxides in flue gases, in which process a reducing agent containing composition is mixed with flue gas and the mixture achieved is brought into contact with a catalyst. In accordance with the invention, the composition contains e.g. 1 to 60% of weight of ammonium formate. Especially a low freezing point can be achieved with such water containing composition. In addition, a good reduction conversion is achieved even at low temperatures.
