“…During the pyrolysis process, the organic volatile matter of tires, mainly the rubber polymers, are decomposed to lower molecular weight products, oils, and gases, while the inorganic compounds and the nonvolatile carbon black, contained in the waste tire, remain as solid char residue [10]. Many research groups have demonstrated that pyrolytic oils can be used as fuels [11][12][13][14][15][16] or chemical feedstock [17][18][19], the gas can be used as a process fuel [20][21][22][23], and the char has the potential to be used as carbon black or activated carbon (AC) [24][25][26]. The yields and characteristics of pyrolysis products depend on the waste tires feedstock (composition and particle size) and the operating parameters, such as temperature, heating rate, vapors/solid residence time, and atmosphere.…”

The present study investigates the potential of waste tires to produce a valuable adsorbent material for application in wastewater treatment. In the first stage, the pyrolysis of ground rubber tire was explored using non-isothermal and isothermal thermogravimetric analysis experiments. The effect of operating parameters, such as heating rate and pyrolysis temperature, on the pyrolysis product yields was considered. The slow pyrolysis of ground rubber tire was taken up in a large-scale fixed-bed reactor for enhanced char recovery. Four pyrolysis temperatures were selected by thermogravimetric data. The product yields were strongly influenced by the pyrolysis temperature; at higher temperatures, the formation of more gases and liquid was favored, while at lower pyrolysis temperatures, more char (solid fraction) was formed. The produced chars were characterized in terms of mineral composition, textural properties, proximate analysis, and structural properties to identify the relationships between the pyrolysis temperature and the char properties. In a second step, a series of activated chars were prepared, starting from the pyrolytic chars via chemical and/or physical activation methods. Then, the activated chars were characterized and tested as adsorbents for atrazine and ibuprofen. Adsorption experiments in aqueous media were carried out in a small-scale batch reactor system. Chemical activation seems appropriate to significantly reduce the inorganic compounds initially present in ground rubber tire and contribute to an important increase in the surface area and porosity of the chars. Adsorption experiments indicated that chemically activated chars exhibit high aqueous adsorption capacity for atrazine.

“…Utilization of aryl halides for arylation of amines using catalysts based on copper as a cheap and biogenic element potentially enables simple and safe destruction (dehalogenation) of waste non-biodegradable aryl halides to the corresponding aryl amines. Produced aromatic amines could be suitable for subsequent utilization as synthetic intermediates or for energy utilization as the refuse-derived fuel (RDF) [119]. The main advantage of the possible utilization of mentioned C-N cross-coupling reactions compared to C-C or C-O couplings is the minimization of the risk of the potential undesirable formation of highly toxic and thermodynamically stable polyhalogenated biphenyls, dibenzo-p-dioxins, or dibenzofurans as the by-products of arylation reactions [120].…”

Copper-Catalyzed Reactions of Aryl Halides with N-Nucleophiles and Their Possible Application for Degradation of Halogenated Aromatic Contaminants

This review summarizes recent applications of copper or copper-based compounds as a nonprecious metal catalyst in N-nucleophiles-based dehalogenation (DH) reactions of halogenated aromatic compounds (Ar-Xs). Cu-catalyzed DH enables the production of corresponding nonhalogenated aromatic products (Ar-Nu), which are much more biodegradable and can be mineralized during aerobic wastewater treatment or which are principally further applicable. Based on available knowledge, the developed Cu-based DH methods enable the utilization of amines for effective cleavage of aryl-halogen bonds in organic solvents or even in an aqueous solution.

“…Em Lei et al, (2016) e Mohan et al, (2021), verificaram que o consumo específico de diesel, o consumo de energia e emissões de gases foram menores com as misturas de diesel e levulinato de etila, sugerindo maior eficiência de conversão de combustível para as misturas de combustível e a capacidade promissora do levulinato para o meio ambiente. Além disso, os LEV como aditivos de combustíveis facilitam a combustão completa, devido à maior oxigenação de sua cadeia, conduzindo a uma combustão completa com menor emissão de gases poluentes (Nelson et al, 2022).…”

A produção de biocombustíveis e seus aditivos constituem alternativas diante do uso combustíveis fósseis. Os levulinatos (LEV) derivados da celulose, e os acetais (ACET) derivados da hemicelulose, são incorporados a combustíveis, devido a suas propriedades físico-químicas. No entanto, a produção em escala industrial requer a compreensão dos respectivos processos produtivos, que necessita de estudos científicos. Deste modo, a presente revisão visa a partir de embasamento teórico, discutir as recentes atualizações sobre (i) aplicação dos compostos como aditivos de combustíveis de acordo com suas características físico-químicas, (ii) reaproveitamento de matérias-primas e potencial de mercado, (iii) elucidação das vias catalíticas e catalisadores aplicadas, (iv) uso de simuladores de processos químicos em rotas de conversão de biomassa em produtos de interesse. A partir do levantamento bibliográfico, sistemas reacionais com conversão de 90% associada à separação de componentes de interesse consistiram em cenários possíveis, como a simulação da produção do solketal, reação homóloga aos processos de esterificação e acetalização.
