The present invention describes a process for capturing COusing an optimized mixture of water and alcohols with alkali hydroxides, such as KOH and NaOH, for absorption of COfrom gaseous mixtures. The process shows high efficiency and low volatility and corrosivity rate of the solvent, in addition to allowing cost reduction for installation and maintenance of reactors and reducing solvent loss. The present invention also describes a process for regenerating solvent or its reuse, carried out by chemical precipitation, continuously and not in batch, through the reaction with alkaline earth oxides, such as CaO and MgO, and/or alkaline earth hydroxides, such as Ca(OH)and Mg(OH), for the formation of carbonates, such as CaCOand MgCO, which can be discarded in nature without any environmental issue or can be used commercially in industry or agriculture.

Process for capturing CO2 and process for continuously regenerating solvent

A process of chemical cleavage of leather or skins containing chromium using sodium, potassium or calcium methylates (CHO) or ethylates (CHCHO), producing chromium hydroxide (green paste), ammonium sulfate and liquid fertilizer. The chromium trioxide III (CrO) obtained was used in the production of Fe—Cr alloy. The liquid fertilizer was applied to strawberry, violet and acerola crops, and can be applied to other types of crops. The fertilizer is also compatible with pesticides, being able to compose a composition containing fertilizer and pesticide or even used to obtain products containing fertilizers and pesticides, which allow application in a single step, exempting the process in the field A solid NPK fertilizer formulation obtained by combining N recovered from waste and homogeneously mixed with K and P salts.

The present invention describes a process for producing nanostructured material, produced from polymer waste doped with alkaline metals and/or alkaline earth metals, which is capable of capturing and storing CO. The process for obtaining the material uses waste generated by the polymer industry and is therefore environmentally sustainable. The product produced, that is, the nanostructured material, shows high COabsorption capacity, being able to absorb up to 80% by weight in mass in CO. In addition, the product produced shows low density, an important characteristic for application in vehicles. Therefore, the product obtained can be used for capturing and storing COemitted by different emission sources, mainly mobile sources such as vehicles, but can also be used in industries such as the mining industry, oil industry, inter alia, in addition to the automotive industry.

The invention refers to the process of obtaining porous spheres based on CaO modified with carbon nanotubes for the capture of CO. The invention also refers to the spheres obtained and their use to capture COgenerated by a vehicular internal combustion engine, aiming to reduce the amount of COreleased into the atmosphere.

The present invention describes the process of preparing ceramic materials for absorption of acidic gases, mainly carbon dioxide, in exhaust systems and/or present indoors. Ceramic materials are formed by a mixture of alkali carbonate with alkaline earth metal oxide/hydroxide associated with a binding component, but non-limiting. The alkali carbonate comprises sodium, potassium carbonate, or a mixture of both. The alkaline earth metal oxide/hydroxide may be formed from magnesium oxide or magnesium hydroxide as well as calcium oxide and/or calcium hydroxide.
