Abstract
PROCESSO DE ALQUILAçãO EM FASE CRìTICA. A presente invenção refere-se a um processo para a produção de etilbenzeno pela etilação de benzeno na fase crítica, em uma zona de reação contendo um catalisador de alquilação de aromáticos de crivo molecular compreendendo zeolita beta promovida com cério. Um polietilbenzeno é suprido à zona de reação e para contato com a zeolita beta promovida com cério, com uma razão molar de sílica/alumina dentro da faixa de 20 - 500. A zona de reação é operada em condições de temperatura e pressão em que o benzeno esteja na fase supercritica, para causar a etilação do benzeno e a transalquilação de polietilbenzeno e benzeno na presença do catalisador de zeolita beta. Produz-se um produto de alquilação contendo etilbenzeno como produto principal, com a produção concomitante de subprodutos alquilados mais pesados de no máximo 60% em peso de etilbenzeno. A zona de reação de alquilação é operada sob condições que forneçam um rendimento de subproduto compósito de propil benzeno e butil benzeno com relação ao etilbenzeno que seja de, no máximo, metade do rendimento de subproduto correspondente para zeolita beta promovida com lantânio. A produção de etilbenzeno na zona de reação de alquilação em fase crítica é acompanhada da reciclagem de um componente aromático polialquilado do produto de reação de volta para a zona de reação.
