Abstract

<B>PROCESSO DE DESAROMATIZAçãO DE HIDROCARBONETOS POR ADSORçãO<D>. é descrito um processo de desaromatização de hidrocarbonetos por adsorção, para cargas de hidrocarbonetos contaminadas com desde 0,1 até 15% em peso de compostos aromáticos, em que a carga é adsorvida em leitos A-G de adsorventes zeolíticos para adsorção dos contaminantes aromáticos, purgada com uma corrente de gás combustível para retirada de hidrocarbonetos parafínicos/isoparafínicos/naftênicos retidos nos poros do adsorvente, seguido de dessorção dos compostos aromáticos adsorvidos com auxílio de uma corrente de gás combustível aquecido e resfriamento do leito visando o reinício da etapa de adsorção do ciclo seguinte. O processo é efetuado de acordo com os princípios de TSA (''Thermal Swing Adsorption'') e permite recuperação de até 98% dos hidrocarbonetos parafínicos;naftênicos da carga inicial, com teor de aromáticos inferior a 100 ppm peso.
