Abstract
Official abstract text for this publication.
Byproduct formation in aromatic alkylation processes is reduced when different polyalkylated aromatic compounds are first fractionated into separate streams enriched in these respective polyalkylated aromatic compounds, and the separate streams are sent to different transalkylation reaction zones, which may or may not be in the same reactor. The different transalkylation reaction zones allow for greater control of the transalkylation of the respective polyalkylated aromatic compounds, such as diisopropylbenzene (DIPB) and triisopropylbenzene (TIPB) that accompany the alkylation of benzene with propylene in a process for cumene production.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transalkylating a hydrocarbon feed stream comprising first and second polyalkylated aromatic transalkylation agents, the method comprising: (a) separating the hydrocarbon feed stream to provide a first transalkylation feed stream enriched in the first polyalkylated aromatic transalkylation agent and a second transalkylation feed stream enriched in the second polyalkylated aromatic transalkylation agent, wherein the first and second polyalkylat…
