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: E1 C6H5CH3 + H₂ → C6H6 + CH4 82 C6H4(CH3)2 + H₂ → C6H5CH3 + CH4 €3 C6H3(CH3)3 + H₂ → C6H4(CH3)2 + CH4 In addition, an unwanted side reaction occurs, in which benzene dimerizes to form diphenyl [C6H5C6H5]. 2 C₂H₂ C6H5C6H5 + H₂ A process stream containing 5 mol % benzene [C6H6], 20 mol% toluene [C6H5CH3], 35 mol% xylene [C6H4(CH3)2], and 40 mol% pseudocumene [C6H3(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 ? X ? P 84 Reactor Hydrogen Gas ? H₂ Light Gases ? H₂ ? M Condenser Aromatics ? B ?T ?
