Abstract
"PROCESSO CATALìTICO PARA TRANSFORMAçãO DE ALQUILADOS PESADOS EM LINEAR ALQUIL BENZENO E UTILIZAçãO DE CATALISADORES SóLIDOS áCIDOS. A presente invenção está de um modo geral relacionada ao processo para transformar alquilados pesados, com cadeias alquílicas maiores que C~ 6~, oriundos do processo de alquilação de benzeno com olefinas de cadeia longa, em compostos aromáticos monoalquilados e à utilização de catalisadores nesse processo. O processo descrito na presente invenção é um processo catalítico, apresentando as faixas de condições ótimas de reação em termos de temperatura, pressão, tempo espacial e concentração dos reagentes, para a transformação eficiente de polialquilados, subprodutos do processo de produção de linear monoalquilbenzenos, em novos compostos aromáticos monoalquilados. A presente invenção diz respeito também à utilização de catalisadores sólidos à base de sítios ácidos no processo para transformar alquilados pesados, com cadeias alquílicas maiores que 6, oriundos do processo de alquilação de benzeno com olefinas de cadeia longa (C~ 10~-C~ 14~), em compostos aromáticos monoalquilados. Esse catalisador é eficiente e seletivo para a geração de mais linear monoalquilbenzenos a partir dos subprodutos polialquilados. O processo de transformação de polialquilados em monoalquilbenzenos, pode ser operado em batelada, em reator contínuo com agitação como também em reatores contínuos de leito fixo.CATALYTIC PROCESS FOR TRANSFORMATION OF HEAVY ALKYLATES IN LINEAR BENZENO ALKYLES AND USE OF ACID SOLID CATALYZERS. benzene with long chain olefins in monoalkylated aromatic compounds and the use of catalysts in this process The process described in the present invention is a catalytic process, presenting the optimal reaction conditions in terms of temperature, pressure, spatial time and concentration. of the reagents for the efficient transformation of polyalkylates, by-products of the process of producing linear monoalkylbenzenes, into novel monoalkylated aromatic compounds The present invention also relates to the use of solid acid site-based catalysts in the process for transforming heavy alkylates such as m alkyl chains greater than 6 from the alkylation process of benzene with long chain (C 10 -C 14) olefins in monoalkylated aromatic compounds. This catalyst is efficient and selective for the generation of more linear monoalkylbenzenes from polyalkylated byproducts. The process of transforming polyalkylates into monoalkylbenzenes can be batch operated, continuous stirred reactor as well as continuous fixed bed reactors.
