Question
Hydrodealkylation is a process in which side chain alkyl groups (like methyl) are removed from aromatics by reaction with hydrogen. The following reactions take place in the reactor: In addition, an unwanted side reaction occurs, in which benzene dimerizes to form diphenyl [C6H5C6H5] E4 2 C6H6C6H5C6H5 + H₂ A process stream containing 5 mol % benzene [CH], 20 mol% toluene [CH₂CH3], 35 mol% xylene [C6H4 (CH3)₂], and 40 mol% pseudocumene [CH₂(CH3)3] is fed to a hydrodealkylation plant. This process stream is mixed with hydrogen gas in 5:1 gas-aromatics ratio before being fed to the reactor. A condenser separates hydrogen and methane from the other reactor products (lumped as aromatics). Feed ?B ?T ?
