Abstract

Patente de Invenção: <B>"ISOMERIZAçãO DE XILENO"<D>. é descrito um processo para a isomerização de uma alimentação que contém etilbenzeno e xileno, processo este que compreende as etapas de: (a) contatar a alimentação sob condições de conversão de etilbenzeno com um primeiro componente catalisador particulado que compreende uma peneira molecular tendo um índice de Constrição de 1-12, as partículas do dito primeiro componente catalisador tendo uma razão de superfície para volume de 3,14 (80) a menos do que 7,86^ mm-1^ (200 polegadas^ -1^), e a etapa de contatar convertendo o etilbenzeno na alimentação para formar um produto esvaziado de etilbenzeno; e em seguida (b) contatar o produto esvaziado de etilbenzeno sob condições de isomerização de xileno com um segundo componente catalisador.
