Resumo: | This study aimed to analyze the advantages of limestone calcination through a conventional microwave heating technique. For such a purpose, the microwave was merged by hybrid heating and a refractory ceramic internally coated with copper oxide was used with a conventional muffle furnace. It has also been analyzed the behavior of calcining limestone with different masses and variations in retention time using a muffle furnace and microwaves, both with and without using the refractory ceramic. Afterwards, the process has been modeled so as to analyze temperature versus retention time. As a result, calcination using a microwave susceptor with the refractory ceramic substance proved to be a process that takes 35% less time than conventional methods. Furthermore, there has been a reduction in 66.1% of energy expenditure. It was also observed that the new procedure offers advantages in reduced greenhouse gases emissions on account of the release of only a single substance, ease of air treatment in industrial environments and being a more economically viable process for limestone calcination, which can be further utilized by companies belonging to such a sector. Its patent deposit number BR 202018073002-4 U2 in INPI. |

Nesse tipo de processamento, a energia é transferida diretamente no interior do material através de processos de interação molecular e atômica com o campo eletromagnético. O objetivo do presente trabalho foi analisar as vantagens da calcinação do calcário usando microondas com relação à utilização de uma técnica de aquecimento convencional. Para esta investigação, utilizou-se o aquecimento híbrido promovido pela junção das microondas e de um refratário cerâmico revestido internamente por óxido de cobre e o aquecimento convencional de uma mufla. Analisou-se também o comportamento de calcinação das rochas de calcário com diferentes massas e variações no tempo de retenção, utilizando a mufla e o microondas com e sem o uso de refratário cerâmico, com posterior modelagem do processo para análise da temperatura em função do tempo de retenção.Como resultado da calcinação no microondas com o susceptor mostrou-se um processo que leva 35% menos tempo do que os métodos convencionais. Além disso, houve redução de 66,1% no gasto de energia. Observou-se também que o novo procedimento oferece vantagens na redução da emissão de gases de efeito estufa por liberação de apenas uma substância, facilidade no tratamento do ar em ambientes industriais e por ser um processo mais viável economicamente para a calcinação do calcário, que pode ser posteriormente aproveitado por empresas pertencentes a esse setor.
