Abstract

a presente invenção refere-se a um processo para produzir paraxileno uma matéria-prima de hidrocarboneto compreendendo benzeno e/ou tolueno é colocada em contato com um reagente de alquilação compreendendo metanol e/ou éter dimetílico em uma zona de reação de alquilação em condições de alquilação na presença de um catalisador de alquilação para produzir um produto alquilado compreendendo xilenos. o catalisador de alquilação compreende uma peneira molecular com um índice de restrição < 5 e as condições de alquilação compreendem uma temperatura menor que 500°c. pelo menos parte do produto alquilado é fornecido a uma unidade de recuperação de paraxileno para recuperar paraxileno e produzir uma corrente esgotada em paraxileno, que é então colocada em contato com um catalisador de isomerização de xileno em condições eficazes para isomerizar xilenos na corrente esgotada de paraxileno e produzir uma corrente isomerizada que possui uma maior concentração de paraxileno que a corrente esgotada em paraxileno. pelo menos parte da corrente isomerizada é então reciclada para a unidade de recuperação de paraxileno para recuperar o paraxileno nela.
