Methods and apparatuses are provided for producing hydrocarbons. A method for producing hydrocarbons may include two or more reactors having a distributed aromatic rich feed and hydrogen system. Using this configuration, the aromatic rich feed and hydrogen streams are split equally to all reactors wherein each reactor contains a catalyst. The outlet from the last reactor may include a recycle that may be injected into the inlet of the first reactor.
