Abstract
A process for producing benzene comprising the steps of: (a) separating a source feedstream comprising C5-C12 hydrocarbons including benzene and alkylbenzenes into a first feedstream comprising a higher proportion of benzene than the source feedstream and a second feedstream comprising a lower proportion of benzene than the source feedstream and subsequently,(b) contacting the first feedstream in the presence of hydrogen with a first hydrocracking catalyst, and(c) contacting the second feedstream with hydrogen under second process conditions to produce a second product stream comprising benzene, whereini) the second process conditions are suitable for hydrocracking and step (c) involves contacting the second feedstream in the presence of hydrogen with a second hydrocracking catalyst,ii) the second process conditions are suitable for toluene disproportionation and involve contacting the second feedstream with a toluene disproportionation catalyst oriii) the second process conditions are suitable for hydrodealkylation.
