Abstract

produção de aromáticos alquilados. a presente invenção refere-se a um processo para a produção de aromáticos alquilados contatando uma corrente de alimentação compreendendo um aromático alquilável, um agente de alquilação e quantidades de traços de água e impurezas na presença de primeiro e segundo catalisador de alquilação, em que a água e a impurezas são removidas para melhorar a duração de ciclo de tais catalisadores de alquilação. água e uma porção de impurezas são removidas em uma zona de desidratação. uma primeira zona de alquilação tendo um primeiro catalisador de alquilação que, em algumas modalidades, é uma peneira molecular de poro grande, atua para remover uma porção maior de impurezas, tais como nitrogenados e outras espécies, e alquilar uma porção menor do composto aromático alquilável. uma segunda zona de alquilação que, em algumas modalidades, é uma peneira molecular de poro grande, atua para remover uma porção maior impurezas, tais como nitrogenados e outras espécies, e alquilar uma porção menor do composto aromático alquilável. uma segunda zona de alquilação que, em algumas modalidades, é uma peneira molecular de poro médio, atua para remover uma porção menor de impurezas e alquilar uma porção maior do composto aromático alquilável.production of alkylated aromatics. The present invention relates to a process for the production of alkylated aromatics by contacting a feed stream comprising an alkylatable aromatic, an alkylating agent and trace amounts of water and impurities in the presence of the first and second alkylation catalysts wherein Water and impurities are removed to improve the cycle life of such alkylation catalysts. Water and a portion of impurities are removed in a dehydration zone. a first alkylation zone having a first alkylation catalyst which, in some embodiments, is a large pore molecular sieve, acts to remove a larger portion of impurities, such as nitrogenates and other species, and to alkylate a smaller portion of the alkylatable aromatic compound. . a second alkylation zone which, in some embodiments, is a large pore molecular sieve, acts to remove a larger portion of impurities, such as nitrogenous and other species, and to alkylate a smaller portion of the alkylatable aromatic compound. a second alkylation zone which, in some embodiments, is a medium pore molecular sieve, acts to remove a minor portion of impurities and to alkylate a larger portion of the alkylatable aromatic compound.
