Abstract
In a process in which a hydrocarbon stream is hydrogenatively dealkylated to prepare benzene, small amounts of naphthalene may occur in the crude product. Instead of isolating and recovering such naphthalene, it is recycled to extinction so that the process comprises the hydrogenative conversion of the minor amount of naphthalene to benzene and methane.
