Abstract
A process for the reduction of naphthalene in process streams containing alkylaromatic solvents. Naphthalene is contacted with alkylbenzenes in a distillation column reactor in the presence of transalkylation catalyst to produce alkylnaphthalenes which are concurrently separated by fractional distillation as bottoms and the alkylbenzenes are separated as overheads.
