Systems and processes for maximizing the production of benzene and para-xylene from heavy reformate are provided. An integrated process and system may include a C9 dealkylation reactor, a transalkylation reactor, and a C10+ dealkylation reactor. The integrated process and system for producing benzene and para-xylene may be configured to additionally produce alkanes in the presence of hydrogen or olefins in the absence of hydrogen. The transalkylation reactor may perform transalkylation of product from the C9 dealkylation reactor and xylene isomerization.
