Abstract

"PROCESSO DE ADSORçãO/DESSORçãO PARA REMOçãO SELETIVA DE NITRILAS DE UMA ALIMENTAçãO DE HIDROCARBONETO". Um processo de adsorção/dessorção para remoção seletiva de nitrilas de uma alimentação de hidrocarboneto inclui as etapas de: (a) proporcionar uma alimentação de hidrocarboneto possuindo um conteúdo de nitrila menor do que ou igual a cerca de 400 ppm; (b) proporcionar um adsorvente para remoção seletiva de nitrila de uma alimentação de hidrocarboneto compreendendo uma mistura substancialmente homogênea de um zeólito não-ácido, catiónico, e uma matriz de óxido inorgânico, possuindo um zeólito um índice de acessibilidade entre cerca de 0,1 a cerca de 0,4; (c) contactar a alimentação e o adsorvente nas condições de adsorção de nitrila por meio das quais pelo menos cerca de 80% do conteúdo de nitrila é adsorvido pelo adsorvente durante o contacto com pelo menos cerca de 200 volumes de alimentação por volume de adsorvente de modo a proporcionar um adsorvente usado possuindo moléculas de nitrila adsorvidas sobre o mesmo; e (d) contactar o adsorvente usado com um dessorvente nas condições de dessorção de modo a remover as moléculas de nitrila e proporcionar um adsorvente renovado.
