Title in Portuguese
Estudo do efeito do suporte em eletrocatalisadores baseados em páladio e cobre aplicados em reatores de eletrólito polimérico - tipo célula a combustível para co-geraçâo de energia e metanol a partir do metano
Keywords in Portuguese
cogeração química e energética
metano em metanol
reator de eletrólitos poliméricos - tipo célula de combustível
Abstract in Portuguese
O metano é um dos principais gases estufa, advindo da ação antropogênica, para atenuar esse problema, transformá-lo em um insumo industrial pode ser de grande interesse. Para esse fim o catalisador PdCu preparado em diferentes composições foi aplicado como ânodo em um reator de eletrólito polimérico - tipo de célula de combustível para converter metano em produtos oxigenados e energia em condições amenas de temperatura e pressão. As curvas de polarização realizadas usando reator de eletrólito polimérico. As análises qualitativas do efluente do reator de eletrólito polimérico por FTIR identificaram produtos como íons metanol, carbonato e formiato a partir da oxidação parcial do metano para todos os materiais. Um método de PLC foi usado para quantificar este produto. Além disso, observou-se que à medida que o potencial elétrico do reator aumenta, a geração de produtos diminui. Os melhores resultados para conversão de metano em metanol e cogeração de energia foram obtidos a partir de Pd80Cu20/ATO devido aos melhores efeitos de ativação de H2O e sítio de adsorção para oxidação de CH4.
Title in English
Study of the effect of the support on electrocatalizers based on paladium and copper applied in polymeric electrolyte reactors - fuel cell type for co-generation of energy and methanol from methane
Keywords in English
chemical and energy cogeneration
methane in methanol
polymeric electrolyte reactor - fuel cell type
Abstract in English
Methane is one of the main greenhouse gases, arising from anthropogenic action, to mitigate this problem, transforming it into an industrial input can be of great interest. For this pressure purpose, PdCu prepared in different configurations was applied as a fuel-type polymeric anode to convert methane into oxygenated products and energy under temperature and temperature conditions. Polarization curves were performed using a polymeric electrolyte reactor. Effluent from polymeric electrical effluent by FT identified ions such as methanol, FT, and formate from all carbonaceous IR partial methane products for all carbide partial quantization product materials from all eligible IR products. HPLC method was employed to quantify this product. In addition, it was observed that as the electrical potential of the reactor increases, the generation of products decreases. The best for converting methane to methanol from energy cogeneration were obtained from an energy conversion for the best effect/outcome of H2O results and from P cogeneration announcements for the Pd80Cu20 site.
