Abstract: The present invention relates to a method of optimization for continuous combustion systems, which reduces fuel consumption, exhaust emissions and particulate matter. The operating principle is based on the introduction of small amounts of hydrogen in the fuel intake duct of the system, or preferably along the continuous burning chamber, with the aim of optimizing the burning of traditional fuels, improving the parameters of the combustion reaction, the effect of the process in question will increase the temperature of the walls of the chamber, ensuring re-ignition and a more complete combustion and consequently reducing the required fuel flow feed. This optimized combustion will increase the combustion efficiency and reduce its environmental impact.

Abstract: The present invention is directed to bioactive microcapsules and to the process for their production. More in particular, the present invention relates to the production of bioactive microcapsules, or porous microspheres by a water-in-oil (W/O) microemulsion method combined with interfacial polymerization, involving the full or partial covalent immobilization of biocides and/or modified biocides within the microcapsules shell, or porous microspheres. In addition, the present invention further relates to the use of said bioactive microcapsules/microspheres for controlled release of biocides in antifouling application and their incorporation in matrices such as marine coatings.

Abstract: The present invention is related to a new method to produce natural water-based glues made of two components, designed to glue lignocellulosic surfaces, mainly cork and wood. The mentioned process comprises the extraction of the aqueous phase of a mixture resulting from liquefying cork dust and/or cork granules, process that is commonly referred to as depolimerization process of cork; evaporation of the aqueous phase, therefore obtaining a first component consisting of a gel composed by the soluble components of the liquefying mixture; mixing and homogenizing of this gel with the second component that consists of a curing aliphatic compound; and, optionally, addition and mixture to “cork dust” to the previously mentioned mix.

Abstract: Stoppers made from composite material for sparkling wines consisting of two types of cork agglomerate which are closely bonded and produced from two ranges of granulates of different granulometry, where the joining surface between the two agglomerates is irregular due to their interpenetration. A production process of such stoppers by individual molding (piece by piece), where there is simultaneous feeding of two types of granulate and respective additives into a mold. The mold is then closed and the material compressed and heated for an appropriate time for polymerization. The granulates used are normally treated with a reactive agglomerant consisting of, for example, quasi-prepolymer based on TDI or quasi-prepolymer based on MDI base. After de-molding, the unfinished stopper is stabilized, and later machined to the final dimensions.
