Abstract

"PROCESSO PARA A PRODUçãO DE ALQUILBENZENO". Um processo para a produção de alquilbenzeno inclui as etapas de introduzir benzeno e um alimento de olefina dentro de uma primeira zona de reação de alquilação na presença de um primeiro catalisador de alquilação sob as primeiras condições de reação de alquilação para produzir alquilbenzeno e um vapor contendo olefina não convertida; absorver a olefina não convertida dentro de uma corrente aromática contendo benzeno e alquilbenzeno; e, introduzir a corrente aromática contendo a olefina absorvida dentro de uma segunda zona de reação de alquilação contendo um segundo catalisador de alquilação sob as segundas condições de reação de alquilação para converter a olefina absorvida e pelo menos um pouco do benzeno da corrente aromática para alquilbenzeno. O processo é particularmente vantajoso para a alquilação de benzeno com etileno para produzir etilbenzeno. Cerca de 99.9% da conversão de etileno é obtida no total, com uma redução substancial no catalisador requerido.
